peedometer features two trip meters and odometer (miles). A remote mount TRIP / CALIBRATION button is included. Calibration is as easy as pressing a button and driving one measured mile. Just re-calibrate the speedometer whenever changes are made and the speedometer will automatically adjust for the changes and accurately indicate speed. Speedometers come calibrated for 16,000 pulses per mile.

These electronic speedometers are designed to work with both hall effect senders and magnetic pickup sensors. Any speed sender or electronic module that meets the following conditions can be used with our speedo: Pulse range generated proportional to the vehicle speed, Signal with minimum 3V peak to peak signal - typical for 3-wire hall effect and 2 wire vehicle speed sensor outputs, 4000-200,000 pulses per mile (16,000 is typical).

The Tachometer works with most 0.5-6 PPR (pulses per revolution) vehicles (1 to 12 cylinder). Our tachometers are designed to work with a wide variety of ignition types, including standard inductive coil (-) connection and any electronic ignition system with a clean tachometer output signal.

The 3-3/8" SCX performance in-dash Speedometers and Tachometers feature high-speed stepper motor movement, LED through-the-dial lighting, Orange / Red illuminated pointer, and easy-install u-clamp.
