TACH PROGRAMMING & TACH SIGNALS
INTRODUCTION
This system has 3 methods of monitoring the engine running. Option #1 controls how the system monitors the
engine running.
1. Tachless Low Level Mode - Default. When vehicle is remote started, the battery voltage rate will go up
because the Alternator starts working.
2. Tach Reference Mode – Monitors Engine R.P.M. - Most reliable method, see Tach programming below.
3. Tachless High Level Mode - When vehicle is remote started, the battery voltage rate will go up (0.5V)
because the Alternator starts working.
4. Hybrid Mode – For electric motors that are computer controlled. This provides a 4 second (option24-1) crank
output to activate the start sequence on Hybrid vehicle. Don’t use on vehicles with gas or diesel engine, that
doesn’t monitor stalled engine or low battery voltage.
Tach Reference Mode: Provides reliable remote starting performance though engine speed sensing. When using
Tach Reference Mode, the Red/White wire is used for Tach signal [Engine RPM] input. Most modern engines
include various points where the Engine Speed [Tach] or A/C signal may be obtained. Tach Signal examples: Fuel
Injection Solenoids, Negative (-) side of ignition coil, at the Distributor or Ignition Control Module, Coil Pack, Engine
Computer, or Crankshaft Sensor. Sometimes an Alternator Stator pin can be used. These Tach Signal locations
mentioned are provided as a guide, your vehicle may differ. Some locations will NOT be a good location for Tach
source due to RF noise or Computer Data.
Note: When using a Databus module for Tach signal, don’t connect up the Tach wire. This will create a
conflict. The System can only use one Tach source.
TACH PROGRAMMING:
1. Red/White wire should be connected to a valid Tach source.
2. Start engine with key.
3. Press program button 5 times for option mode, then wait for 5 light flashes and/or 5 horn honks.
4. Push program button once more for option 1. (You must get one light flash and/or honk after button is pressed.)
5. Press brake pedal or Button on remote transmitter. The lights and horn will flash twice (Tach Mode) and the unit
will start recording the Tach signal. The lights and or honk flash once for program confirmation.
6. If there no Tach signal, the unit will exit Tach learn mode in 20 seconds with one long flash or honk. Try another
tach source or try the tach finder to locate another wire.
7. Turn ignition off to exit program mode, one long flash and or honk.
