This clever unit displays the current gear selected on virtually any vehicle with an RPM signal and a road speed signal. A large backlit LCD window displays the gear number (up to 7), while a row of 7 LEDs above provides a 5-stage sequential shift light. Compact housing measures 50mm tall x 40mm wide x 21mm thick (2" x 1 9/16" x 13/16").

Microprocessor control compares the RPM signal to the speed signal to calculate which gear is engaged. You don't have to do any math, even during setup! Programming the gears is as easy as driving at a constant speed (ANY speed) in each gear for just a few seconds. The RPM and speed are automatically stored in memory, along with the ratio of RPM to speed. Programming the shift lights is just as easy. Simply bring the RPMs to the first alert level, then back off the throttle. Then bring the RPMs to the top alert level and back off. The unit stores those two values and calculates the steps in between.

12-volt, negative ground indicator is compatible with breaker-point ignitions or any ignition system with an RPM signal output. Any type of electronic speed sensor can be used, including OEM or aftermarket. The number of pulses per revolution, wheel diameter, and units of speed (mph/kph) do not matter. Instructions included. Tip: The signal wire for programming is left bare, to be touched to chassis ground. We suggest adding a pushbutton switch (sold separately) to access the programming routines.
