TACHLESS MODE
Your system includes a Tach-less mode that actively monitors and compares the vehicle’s resting voltage versus its
running voltage each time a remote start is performed; [instead of the conventional tach-pulse method]. Smart
Tachless mode adjusts automatically to maintain optimum efficiency over the life of the installation.
IMPORTANT NOTES:
(1) SETUP may be required for the Tachless Mode. If your vehicle has NOT been at rest for a period of time (Hot
engine), then you must drain the surface charge from the battery. Unplug main power harness from system, turn
HEADLIGHTS ON for 4 minutes to drain off excess surface charge on vehicle’s battery then reconnect.
(2) On the rare occasion that Tachless mode does not operate satisfactorily, change the voltage reference level as
described below, or use a different mode such as “Tach Reference” mode, or “Timed Crank” mode.
TACHLESS ADJUSTMENT:
In the event Tachless over-cranks or under-cranks your starter, the settings can be changed. The purpose of
adjusting the “Smart Tachless” Mode is to raise or lower the voltage reference threshold from the 93% default point.
Raising or lowering this 93% point should increase or decrease your cranking time respectively. You can adjust the
range from 79% to 100% in one percent increments. Factory default setting [starting point] is in the middle at 93%
which should work for most vehicles. If you feel you need to fine tune the Tachless mode, then follow the steps
below to adjust its reference level.
1. Open hood (or ground the Blue hood pin wire if no hood pin is installed)
2. Turn the key to the ON position (do not start vehicle).
3. Press program button 5 times, after a few seconds the unit will flash the lights 5 times.
4. Carefully press the program button 24 times to get to option # 24. You must get a light flash after each press. If
the lights didn’t flash, then the unit did not register your button press. Only count the light flash.
5. Press the Lock Button #1 on the remote to decrease by 1% (lights will flash 1X for each press); Press the Unlock
Button #2 to increase by 1% (lights will flash 2X for each press); Press the Trunk Button #3 to reset to 93% (lights
will flash 3X). The unit will stop providing light flashes when you reach the bottom (79%) or the top (100%) of the
adjustment range. If you lost track, then just press Button #3 to reset back to 93% and begin again.
6. Turn Ignition OFF, Close hood (or un-ground the Blue wire) and check operation.
