4-1/2" CAN-Bus Tachometer | 10K RPM | Holley EFI

Holley EFI CAN-Bus Tachometer is built to pull engine RPM directly from the Holley EFI ECU through the CAN network for a cleaner install with no coil signal wiring or external tach input required. Designed for Holley Terminator, Dominator, and Sniper EFI systems, it delivers real-time RPM data while keeping the setup clean and straightforward. A precision stepper motor keeps the needle smooth, stable, and accurate at a glance, while daisy-chain capability makes it easy to run multiple gauges on the same CAN network. With classic analog styling, IPX6-rated construction, and a factory-finished look, it’s built for long-term use. Made in the USA and backed for life.
