Stepper motor gauges are the most precise and stable option available. The pointer is driven by a digitally controlled motor, so vibration never throws off your reading. Your needle stays steady and accurate, whether you’re on rough roads or sitting behind a rumbling engine.

Other gauge styles can’t match that consistency:

Air-core gauges are less accurate and can produce unstable readings when exposed to vibration.

Mechanical gauges can be fairly accurate at first, but their moving parts wear out faster. Over time, readings drift and the pointer tends to bounce.

With a stepper motor gauge, you get accurate readings from the day you install it, and they stay accurate for the life of the gauge.

Don't worry: it's not you, it's us.

When we upgraded our website on 11.16.21, we also switched web hosts, and unfortunately our user accounts were unable to be carried over. We apologize for any inconveniences or confusion this has caused.

You can recreate your account using the same information you previously used, or update it, if you're feeling fresh! Either way, this won't cause without any issues.

If you need to retrieve information about a past order, please contact us. Our support agents are always ready to help you out!

Yes, we can do that for you!
Include a note on your order with how many miles to put on the odometer, or if you are sending in a gauge to modify, let us know to transfer the odometer.

If you exceed your speedometer's maximum speed, the pointer will remain at the maximum speed position, and will not move below the maximum speed position until your speed drops back into a readable range.

Luckily for all of the speed-fiends out there, this will NOT damage the speedometer.

If the speed exceeds the analog range and you are using a GPS speedometer with an LCD display then you can use the digital speed display feature to view your current speed.

Typical gauge power draw is approximately 0.2 amps.

The sender and gauge must be grounded to the same source to operate correctly.

The sender's ground path is its mounting threads. Ensure that what the sender is threaded into is grounded to the same source as the gauge.

Use Teflon paste on the sender threads to secure the seal and maintain a secure ground connection. Teflon tape will NOT assist the ground connection.

Making a comparison to a Temperature Gun reading should be used as a basic comparison only. A temperature gun only measures surface temperature, and does not measure internal temperature. Surface temperature will always be cooler than the coolant inside the engine. A common temperature difference would be between 5 and 25 degrees, between the water temperature gauge and a temperature gun. This depends on the efficiency of the component being shot with the temperature gun to dissipate heat. So, if your gauge reads 195 and you point & shoot and get a reading of 185, you can safely assume that you are seeing a reasonable, and realistic comparison. Only use a temperature gun to make basic temperature comparisons. Understand, that when everything is working correctly, the gauge will usually read higher since the gauge measures core temperature, and the temperature gun measures surface temperature.

Some models of the CJ Speedometer Cluster have a inclinometer feature. The gauge unit will sound an alarm when the inclinometer has not been calibrated.

To calibrate it follow these instructions:

1. Install the gauge in the vehicle.
2. Park your vehicle on level ground (i.e. a level Parking Lot).
3. Power on the gauge.
4. Press the button repeatedly until you see the Inclinometer display.
5. Press and hold the button to access the Inclinometer menu.

6.Select “1. Null” and press and hold the button. The Inclinometer display will show 0° for both pitch and roll.
7. If you desire you can set a warning point (5° to 80°) for the Pitch and/or the Roll. An alarm will sound when the vehicle tips past the warning point.
a. Select the axis you want to set (Pitch or Roll). Press and hold to access the menu. Toggle through to set the degree.
b. Do not press the button for 5 seconds to save the setting.

Each Freedom CAN-bus gauge needs 12 volt DC power to operate. Connect the (Red, White, and Black*) power distribution cable to 12 volt DC power.

The OBDII connection does not provide power to the gauge.

*Red - +12 volts keyed ignition [main gauge power]
White - +12 Volt Dash Lighting [pointer lighting]
Black - ground

If you have some technical knowledge, most of the gauges are straightforward to install. Installation setup may vary due to specific application or vehicle.

Speedhut does NOT offer custom mounting or dash fabrication services. We recommend working with a professional auto shop for gauge installation, custom mounting solutions, and custom dash fabrication.

While Speedhut gauges are intended to enhance and improve your vehicle's dash, they are NOT designed to be exact replacements for stock gauges.

Our gauges are universal and can be adapted to fit almost any automotive application. Because of this, most dashboards will need to be modified or rebuilt in order to mount your project's one-of-a-kind set.

The white wire on the power harness (A-323) provides power to the LED backlighting. You will tie this wire to a 12v source on your headlight switch circuit.

After this is done, whenever you turn your headlights on, the gauge will light up!

Calibrate preset fuel level on dual Speedo/Fuel gauge:

Dual Speedo/Fuel manual calibration:

Manual calibration for standalone fuel level with float-style sender:

Calibrate your Quad gauge fuel level (manual or preset):

Calibrate EL-style fuel level (pre 2022 orders):

Test your float-style fuel sender:

The fuel level gauge can be manually calibrated to your existing fuel tank sender or you can select one of the preset calibration curves. Factory default setting is 240 ohms Empty and 33 ohms Full. No calibration is necessary on senders with this output.

***Selecting a calibration preset***

1. While gauge is powered up, press and hold button down for 10-12 seconds until pointer swings and stops at ‘1/8’ tank then release the button. You are now in calibration mode.

2. Press and release button to toggle between available resistive ohm options (see figure 1). Pointer will travel to each available setting with quick button press. At desired ohm range press and hold button down for 4 seconds to select that range.

3. Pointer will then travel to ‘E’ gauge will exit calibration menu and display current fuel level.

Note: On gauges with LED on front, the LED will blink 2 times to indicate the setting is saved.

*** Manual calibration***

Note: make sure fuel level sensor is hooked up to gauge and is at the appropriate empty or full state you wish to calibrate. Fuel level sensor MUST be attached to gauge during calibration procedure(s).

If your sensor is different from the preset ranges you can manually calibrate the gauge. You will need to program the 'Empty' resistance and the 'Full' resistance.

1. Follow steps 1 & 2 above and select (manual calibration ‘F’ see figure 1).

2. Release button (pointer will oscillate between ‘E’ and ‘F’.)

3. When pointer is at ‘F’ or ‘E’ - press and hold button for 4 seconds to calibrate that condition. For example: If the tank was drained with no gas you would select the Empty position ‘E’ on the dial.

4. Pointer will then travel to ‘E’ or ‘F’ depending on which end you are setting. Gauge will exit calibration menu and display current fuel level. Repeat procedure to set OTHER end point. Note: Until both empty and full points are calibrated the gauge will NOT display the fuel level accurately.

Note: On gauges with LED on front, the LED will blink 2 times to indicate the setting is saved. You can reset gauge calibration as many times as needed by repeating above steps.

The process of programming a fuel level gauge is detailed in the instructions.

They are incredibly simple and straightforward to install! Our GPS Speedometers connect to the Global Positioning System through an antenna, and don't require a transmission sensor. (The antennas are included with the GPS Speedometers, too!) This makes them very easy to install in vehicles that lack electronic sensor output.

The GPS speedometer updates 4 to 5 times per second. The update rate is fast enough to not show any noticeable delay in keeping up with speed under hard acceleration or braking. Our GPS speedometer are used without issues in many performance cars!

If you exceed your speedometer's maximum speed, the pointer will remain at the maximum speed position, and will not move below the maximum speed position until your speed drops back into a readable range.

Luckily for all of the speed-fiends out there, this will NOT damage the speedometer.

If the speed exceeds the analog range and you are using a GPS speedometer with an LCD display then you can use the digital speed display feature to view your current speed.

Our GPS speedometers rarely drop signal. They use a powerful 'active' antenna which perform exceptionally well in all driving environments, including tall buildings, canyons, and extreme weather such as rain and snow. In most cases, the only time you will experience a signal loss is while driving in tunnels or in parking garages.

No, but we offer three different antenna lengths for you to choose from: 5', 9.8' and 15'.

The best location for the GPS antenna to be mounted is on the roof of the vehicle. The GPS antenna is waterproof and magnetic. If the roof is inaccessible, the antenna can be mounted on the top of the dashboard in a place with maximum exposure to the sky.

Metal will block the GPS signal, but the GPS antenna can receive a signal through thin materials like wood, glass, fiberglass, and plastic.

Yes, we can do that for you!

Please tell us your mileage in the 'Order Comments', and we will program your odometer when we build your gauge.

If you already own one of these speedometers you can send it back to us and we can program the miles into the odometer (shipping charges will apply).

No, we do not make mechanical speedometers.

One of the great features of our electronic speedometers is that they are programmable. They are easy to calibrate. You can even re-calibrate if you happen to change your rear-end gear or tire sizes. The overall calibration procedure is very simple.

If you exceed your speedometer's maximum speed, the pointer will remain at the maximum speed position, and will not move below the maximum speed position until your speed drops back into a readable range.

Luckily for all of the speed-fiends out there, this will NOT damage the speedometer.

If the speed exceeds the analog range and you are using a GPS speedometer with an LCD display then you can use the digital speed display feature to view your current speed.

No, our programmable speedometers do not come with a sender. Follow the instructions that come with the speedometer to program it to your vehicle’s OEM transmission sender electric pulse output. If you have an older style cable drive output then we do sell senders that convert the cable drive to an electrical signal. Please contact customer support for more information.

See diagram:

Low pulse count per mile will result in a slow response from the programmable speedometer. Our programmable speedometers can read from 1K to 300K pulses per mile. Most transmissions will output at least 10K or more pulses per mile. However, if your transmission is outputting around 1-5K pulses per mile you might notice a slight delay in speedometer responsiveness.

We recommend hooking up your diesel tachometer to either the alternator R or W terminal, crank sensor signal, or magnetic pulse sensor.

1. To calibrate it, while hold the button down start the engine. The pointer to move to 1k rpm when in calibration
2. Next, move the pointer to where your idle is by holding the button down. If you release and hold down again, it will move the other direction.
3. Release the button, and after a few seconds the pointer will go to 0 and then current rpm.
4. Your calibration is done! It is permanently stored in memory.
5. This can be done multiple times if needed.

To get into PPR (Pulses Per Revolution) calibration, you will press and hold the button down while power the gauge on (or menu button if you have 2 on the front)

You will determine your PPR based on the chart below. While in calibration, pressing and releasing the button will cycle through the options. 

After 5 seconds, the gauge will exit calibration and save the PPR the pointer is currently on, return to 0 then show the RPM reading.

If you have a dual speedometer + tachometer, then you will set the calibration on the screen display instead, holding button down while powering on, press and release button to cycle through menu options, hold the button for 3-4 seconds to select "Set pulses per rev" menu option, then press and release to increase PPR. The PPR will save after 5 seconds of inactivity.

Calibrating single gauge tachometer:

You need to connect the tachometer to the vehicle's ignition system, or ECU tach output if applicable. Exactly where you connect to will depend on your vehicle's fuel delivery system. The PPR (Pulses Per Revolution) calibration will also vary based on where your signal is and how many cylinders your engine is.

If you have a single coil distributor, you will connect the signal to the negative coil terminal.

If you have a coil pack or coil on plug, you will connect to any trigger wire. (The wire that will be a different color from coil to coil)

If you have an OEM ECU, you will likely need a 4.7 KiloOhm pull up resistor tied to 12v to help strengthen the signal.

Please view the diagram below for more information on how to connect a Speedhut Tachometer to an LS ECU.

Setup the Tachometer to run 2 pulses per rev when connecting it to the engines' ECU.

If your tachometer is constantly jumping around, it is likely electrical interference. You can try shielding the signal wire with aluminum foil or foil tape and tie each end to ground, it is pretty common as the components the signal wire ties to tend to be electrically noisy.

The first step to troubleshoot fuel gauge issues is verifying a good connection on signal and ground to the sender. You can either inspect the connections closely, we recommend using a multimeter to measure the ohms at the harness on the gauge side. If you have 0 ohms or open line, you don't have a good connection or the sender is bad.

Next is to ensure it is calibrated, if you have done manual calibration both empty and full conditions need to be set, or it won't read accurately. If you have done a preset calibration, ensure that it matches the ohm range of your fuel sender.
If you don't have a multimeter or don't want to measure the ohms, you can cycle through the presets to see if one works. If not, do manual calibration.
The CJ series gauges are preset to 70-10 ohms and work with stock jeep senders.

If the pointer is rapidly moving, you likely have a bad ground. It could also be electrical interference if you have the signal wire routed near high voltage components like coils, or if it is combined with a fuel pump. 
We recommend using our 2-wire fuel harness that runs a direct ground and signal to the sender.

If your gauge is staying at empty regardless of what preset you use, it likely has a bad connection and isn't getting an ohm reading. Every gauge is tested before it ships.

Our fuel level gauges are programmable, they are compatible with any OEM or aftermarket resistance range. When setting up your gauge, follow the simple calibration setup found in the installation instructions.

Fuel Level Gauge factory default resistance settings are:
240 Ohms = Empty
33 Ohms = Full

Fuel Level Capacitance Universal Sender* (sold separately): If you are using a fuel level gauge from Speedhut with the Fuel Level Sender from Speedhut then use the gauge's factory default range (240 Ohms = Empty and 33 Ohms = Full).

*Additional electronics may be required for use with other brands' fuel level gauges (If used with a fuel level gauge from Speedhut then no additional electronics are required).

The fuel level gauge can be manually calibrated to your existing fuel tank sender or you can select one of the preset calibration curves. Factory default setting is 240 ohms Empty and 33 ohms Full. No calibration is necessary on senders with this output.

***Selecting a calibration preset***

1. While gauge is powered up, press and hold button down for 10-12 seconds until pointer swings and stops at ‘1/8’ tank then release the button. You are now in calibration mode.

2. Press and release button to toggle between available resistive ohm options (see figure 1). Pointer will travel to each available setting with quick button press. At desired ohm range press and hold button down for 4 seconds to select that range.

3. Pointer will then travel to ‘E’ gauge will exit calibration menu and display current fuel level.

Note: On gauges with LED on front, the LED will blink 2 times to indicate the setting is saved.

*** Manual calibration***

Note: make sure fuel level sensor is hooked up to gauge and is at the appropriate empty or full state you wish to calibrate. Fuel level sensor MUST be attached to gauge during calibration procedure(s).

If your sensor is different from the preset ranges you can manually calibrate the gauge. You will need to program the 'Empty' resistance and the 'Full' resistance.

1. Follow steps 1 & 2 above and select (manual calibration ‘F’ see figure 1).

2. Release button (pointer will oscillate between ‘E’ and ‘F’.)

3. When pointer is at ‘F’ or ‘E’ - press and hold button for 4 seconds to calibrate that condition. For example: If the tank was drained with no gas you would select the Empty position ‘E’ on the dial.

4. Pointer will then travel to ‘E’ or ‘F’ depending on which end you are setting. Gauge will exit calibration menu and display current fuel level. Repeat procedure to set OTHER end point. Note: Until both empty and full points are calibrated the gauge will NOT display the fuel level accurately.

Note: On gauges with LED on front, the LED will blink 2 times to indicate the setting is saved. You can reset gauge calibration as many times as needed by repeating above steps.

The process of programming a fuel level gauge is detailed in the instructions.

Fuel Level Capacitance Universal Sender* (sold separately): If you are using a fuel level gauge from Speedhut with the Fuel Level Sender from Speedhut, use the gauge's factory default range (240 Ohms = Empty and 33 Ohms = Full).

*Additional electronics maybe required for use with other brands' fuel level gauges (If used with a fuel level gauge from Speedhut, no additional electronics are required).

If the threads are wrong, you will need an adapter that changes your port to 1/8" NPT. We have some available, ensure you verify it is the right one.

If the sensor fits the threads but is too long, you can try trimming it up to but NOT past the notch. Trimming past the notch will damage the sensor. If it still does not fit, you can get a radiator hose adapter with a 1/8" NPT port.

If the gauge does not sweep on startup, it is not getting power. Verify the red, white, black power harness is connected properly.

If it sweeps but is not reading at all, ensure the signal harness is connected and pressed in firmly on both sides.

If it's still not working, test the signal harness for continuity with a multimeter. If you have both probes on the metal terminal and it reads "OL" or 0 ohms, the harness is bad.  Call or email us to get a replacement harness. You can put paperclips in the harness connector if needed to get a good contact point.

If the harness is testing good, the next step is to measure ohms coming from the sensor while it is warm. Refer to the chart below, if the ohm reading is close to 0 or it's an OL, you need a new sensor. We recommend reading the ohms at the gauge side to verify it is getting to the gauge.

Yes, we have Pyrometer gauges. They are listed as EGT (Exhaust Gas Temperature) gauges.

The sender and gauge must be grounded to the same source to operate correctly.

The sender's ground path is its mounting threads. Ensure that what the sender is threaded into is grounded to the same source as the gauge.

Use Teflon paste on the sender threads to secure the seal and maintain a secure ground connection. Teflon tape will NOT assist the ground connection.

Making a comparison to a Temperature Gun reading should be used as a basic comparison only. A temperature gun only measures surface temperature, and does not measure internal temperature. Surface temperature will always be cooler than the coolant inside the engine. A common temperature difference would be between 5 and 25 degrees, between the water temperature gauge and a temperature gun. This depends on the efficiency of the component being shot with the temperature gun to dissipate heat. So, if your gauge reads 195 and you point & shoot and get a reading of 185, you can safely assume that you are seeing a reasonable, and realistic comparison. Only use a temperature gun to make basic temperature comparisons. Understand, that when everything is working correctly, the gauge will usually read higher since the gauge measures core temperature, and the temperature gun measures surface temperature.

Ensure you are using our sensor, most other sensors will not work with our gauges.

With the harness disconnected from the sensor and the gauge powered on, measure the voltage across the red and black wires in the harness at the sensor end. Here you should see 4.9-5 volts. 

Once you have confirmed the voltage, short the red wire to the white wire, this should make the gauge sweep full scale. 

With the harness still disconnected from the sensor, go to key-on or start the car. With the sensor disconnected the gauge should stay at 0 or the bottom of the scale.

If all those turn out normally, next we'll test the sensor. Disconnect the harness from the gauge, and reconnect it to the sensor. Measure voltage between the white wire (signal from sensor) and black wire (ground) and you should see a range between 0.5 to 4.5 volts. You will need to supply power and ground to the sensor while it's disconnected from the gauge. You can either use short paperclip pieces if needed.

Our fuel pressure gauge isolates the fuel at the sender and does not enter the vehicle. You will not need a fuel pressure isolator to run our gauge. The wire harness and sender are included with the gauge.

Our GM Freedom Speedometer, Tachometer, and Water Temperature gauges are generally universal for vehicles with OEM ECUs supporting J1939 OBD2 protocol (any post 2008 vehicle, select earlier vehicles). For other gauges you should reach out to us to verify if the gauges will work with your vehicle.

If you have an aftermarket ECU, you may need to get a custom programmed gauge. Custom fees may apply. The only aftermarket ECU CAN gauges we have on our website are Haltech, Holley, and for EV BMS we have AEM,  Orion / Zero EV / Thunderstruck, Resolve, and EV Controls

If you have an ECU not listed,  email [email protected] the following info:

1. All the gauge types you want
2. Specify what ECU you have
3. Provide the DBC file/info (you will need to get that from the ECU manufacturer if you don't have it).
   

Our engineers will review the DBC and determine if we are able to make it work on the CAN bus.

Freedom CAN-BUS gauges require an ECU that supports the U.S.A GMC CAN (J1979) protocol. Freedom CAN-BUS gauges operate by receiving data from the ECU (Engine Control Unit) through the OBDII wiring. Before purchasing a Freedom CAN-BUS gauge, please research your vehicle to identify whether it will support both the CAN-protocol AND your desired gauge type output.

The easiest way to see if your vehicle's ECU supports the CAN (J1979) protocol is to check your vehicle's OBDII connector.

CHECKING YOUR OBDII CONNECTOR

If the OBDII connector has wires connecting to pins 4, 5, 6, 14, and 16 then the vehicle supports the CAN-BUS (J1979) protocol.
If the OBDII connector has wires connecting to pins 2 and 10 then the vehicle does NOT support the CAN protocol.

OBDII CAN (J1979) protocol Pinout:
Pin 4 -- Chassis Ground
Pin 5 -- Signal Ground
Pin 6 -- CAN High (data)
Pin 14 -- CAN Low (data)
Pin 16 -- +12volt Battery power (not for use as gauge power)

NOTE: Freedom CAN-Bus gauges CANNOT be connected to a sender or anything that sends a raw signal.

Typically, all vehicles 2008 and newer that are manufactured by the USA, Canada, or the UK, are required to be compatible with the CAN (J1979) protocol. Some manufacturers used the CAN protocol before 2008. Not all gauge types will be supported on your vehicle's ECU. For example, not all ECUs support fuel level output.

Check with your vehicle’s dealer or the manufacturer of the ECU for information about what types of output are supported.

The following gauges will work with all ECUs with the CAN (J1979) protocol:

• Freedom CAN-BUS Speedometers.
• Freedom CAN-BUS Tachometers.
• Freedom CAN-BUS Water Temperature Gauges.
• Freedom CAN-BUS Intake Air Temperature Gauges.
• Freedom CAN-BUS Voltage Gauges (Voltmeter).

The following gauges have limited support on ECUs with the CAN (J1979) protocol:

• Freedom CAN-BUS Fuel Level Gauge is NOT supported on all CAN (J1979) protocol compatible ECUs.

The following gauges will only work with ECUs (with the CAN (J1979) protocol) made by General Motors (GM):

• Freedom CAN-BUS Oil Pressure Gauges
• Freedom CAN-BUS Oil Temperature Gauges
• Freedom CAN-BUS Trans Temperature Gauges

Speedhut Freedom CAN-BUS gauges (individual or daisy chained) will not function when used in conjunction with any other OBDII device. Cycle the gauge power to restore proper gauge function.

Freedom CAN-Bus gauges run off your vehicles OBDII system using the CAN (J1979) protocol. These gauges can only be used on 2008 and newer vehicles (All vehicles 2008 and newer are required to be compatible with the CAN (J1979) protocol). Freedom CAN-Bus gauges CANNOT be connected to a sender or anything that sends a raw signal.

There are two options for connecting the Freedom Gauges to the OBDII system: Plug the gauges directly into the vehicle's 16-pin OBDII Data Link Connector - OR - If needed you can easily 'hard wire' into CAN high and low data lines to free up the OBDII port.

Check with your dealer for more information about what types of output are supported.

• Freedom CAN-BUS Oil Pressure Gauges
• Freedom CAN-BUS Oil Temperature Gauges
• Freedom CAN-BUS Trans Temperature Gauges

• Freedom CAN-BUS Speedometers will work with all CAN (J1979) protocol compatible ECUs.
• Freedom CAN-BUS Tachometers will work with all CAN (J1979) protocol compatible ECUs.
• Freedom CAN-BUS Water Temperature Gauges will work with all CAN (J1979) protocol compatible ECUs.
• Freedom CAN-BUS Intake Air Temperature Gauges will work with all CAN (J1979) protocol compatible ECUs.
• Voltage Gauges (Voltmeter) do not connect to the CAN bus, they just need power harness hooked up.

• Freedom CAN-BUS Fuel Level Gauge is NOT supported on all CAN (J1979) protocol compatible ECUs.

Each Freedom CAN-bus gauge needs 12 volt DC power to operate. Connect the (Red, White, and Black*) power distribution cable to 12 volt DC power.

The OBDII connection does not provide power to the gauge.

*Red - +12 volts keyed ignition [main gauge power]
White - +12 Volt Dash Lighting [pointer lighting]
Black - ground

Some models of the CJ Speedometer Cluster have a inclinometer feature. The gauge unit will sound an alarm when the inclinometer has not been calibrated.

To calibrate it follow these instructions:

1. Install the gauge in the vehicle.
2. Park your vehicle on level ground (i.e. a level Parking Lot).
3. Power on the gauge.
4. Press the button repeatedly until you see the Inclinometer display.
5. Press and hold the button to access the Inclinometer menu.

6.Select “1. Null” and press and hold the button. The Inclinometer display will show 0° for both pitch and roll.
7. If you desire you can set a warning point (5° to 80°) for the Pitch and/or the Roll. An alarm will sound when the vehicle tips past the warning point.
a. Select the axis you want to set (Pitch or Roll). Press and hold to access the menu. Toggle through to set the degree.
b. Do not press the button for 5 seconds to save the setting.

How to calibrate the “Inclinometer” (Inclinometer is not available on all models):

1. Install the gauge in the vehicle.
2. Park your vehicle on level ground (i.e. a level Parking Lot).
3. Power on the gauge.
4. Press the button repeatedly until you see the Inclinometer display.
5. Press and hold the button to access the Inclinometer menu.

6.Select “1. Null” and press and hold the button. The Inclinometer display will show 0° for both pitch and roll.
7. If you desire you can set a warning point (5° to 80°) for the Pitch and/or the Roll. An alarm will sound when the vehicle tips past the warning point.
a. Select the axis you want to set (Pitch or Roll). Press and hold to access the menu. Toggle through to set the degree.
b. Do not press the button for 5 seconds to save the setting.

If you are running GPS only:

•  Verify that the GPS antenna is mounted on the dash, or under fibreglass. It will not work if it is under metal, or inside a building.
• The magnetic side of the antenna must be facing down.
• Ensure the red light on the side of the Speedbox is solid. If it is blinking, the GPS signal is not acquired. It shouldn't take more than 5 minutes to acquire a signal if installed properly.
• Press the button to enter Speedbox offset to see if the pointer moves, then turn it off without pressing button again. This verifies that the motor is working and has power.

If you are running VSS:

• The Speedbox will default to GPS if connected, with VSS as a fallback.
• The Speedbox must be driven over 25 MPH with GPS connected for a couple of miles to calibrate the VSS signal
• If it is still reading off,  set the Speedbox offset. Press the button and the pointer will move up to around 60 mph / 96 kmh. Then press and hold the button to move the pointer to exactly 60 mph or 96 kmh. Releasing and holding the button again will change movement direction. Release the button for about 5 seconds to exit the offset setting and resume operation.
• Verify that your Speed sensor is wired properly, and test it if possible. You will need an oscilloscope or another gauge to test the sensor. 
  

If it is still reading lower, disconnect the speed cable from the speedometer and try to spin the driver by hand to feel for binding. It should spin smoothly.

There are two styles of speed cable: Thread on and clip on.
You can inspect your current speed cable, if it has threads then you need a thread on. If there are no threads, you need a clip on.

We have some speed cables for select makes, if yours is not listed you may need to get a custom speed cable.  You can order a Speedbox with no cable. 

Deluxe Speedometer and Cable services in colorado makes all our Speedbox cables, you just need to mention it's for a Speedhut speedbox.
