“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) On the rare occasion that “Smart Tachless” mode does not operate satisfactorily, change the voltage reference level
as described below, or use a different mode such as “Tach” mode, or “Timed Crank” 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 93% default point.
Raising or lowering this 93% point should increase or decrease your cranking time respectively. The adjustment range is
from 79% to 100% in one percent increments. Follow steps below to adjust the reference level.
1. Turn the key to the ON position.
2. Press program button 5 times, after a few seconds the unit will flash the lights and/or honk horn 5 times.
3. Carefully press the program button 21 times to get to option level 21. You must get a light flash and/or horn honk after
each press. If the lights didn’t flash and/or horn does not honk, then the unit did not register your button press. Only
count the light flash and/or horn honk.
4. Press the Lock Button #1 on the remote to decrease by 1% (lights will flash and/or horn honk 1X for each press); Press
the Unlock Button #2 to increase by 1% (lights will flash and/or honk horn 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
raising or lower again.
5. Turn Ignition OFF and check operation.
NOTE: This Smart Tachless adjustment feature is not available on the RS00 Model that has no remote
transmitters or antenna. If you must use this feature on a RS00, then a remote and an antenna module from an
RS3 or RS4 must be used to set the desired level. Once programmed, remove antenna.
