“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 the CoolStart “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 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 80% to 100% in one percent increments. 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 (Pink wire must be connected!)
3. Press program button 5 times, after a few seconds the unit will flash the lights and/or honk horn 5 times.
4. 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.
5. 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.
6. Turn Ignition OFF, Close hood (or un-ground the Gray wire) and check operation.
NOTE: This Smart Tachless adjustment feature is not available on the RS-1300DP Model that has no remote
transmitters or antenna. If you must use this feature on a RS-1300DP, then a remote and an antenna module
from an RS-1301/3/4DP must be used to set the desired level. Once programmed, remove antenna.
