“SMART TACHLESS” MODE
Your CoolStart system includes a unique voltage monitor called “Smart Tachless” mode. This mode allows this unit to
efficiently start an engine without the use of a tach signal wire. These modules actively monitor the voltage level of the
vehicle to control the starter motor each time a remote start is requested.
IMPORTANT NOTES:
(1) SETUP may be required for Smart 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 unit, turn
HEADLIGHTS ON for 4 minutes to drain off excess surface charge on vehicle’s battery then reconnect.
(2) On the rare occasion that “Smart Tachless” mode does not operate satisfactorily, change the voltage reference level
as described below, or use “Tach Reference” mode.
“SMART TACHLESS” ADJUSTMENT:
In the event “Smart 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 90% default point.
Raising or lowering this 90% point should increase or decrease your cranking time respectively. The adjustment range
is from 80% to 100% in one percent increments. The Default is 90%. Follow steps below to adjust the reference level.
1. Open hood (or ground Gray wire if no hood pin is installed)
2. Turn the key to the ON position
3. Press program button 5 times, after a few seconds the unit will flash the lights 5 times.
4. Carefully press the program button 6 times to get to option level 6. 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 Start Button
#2 to increase by 1% (lights will flash 2X for each press). The unit will stop providing light flashes when you reach the
bottom (80%) or the top (100%) of the adjustment range.
6. Turn Ignition OFF, Close hood (or un-ground the Gray wire) and check operation.
