Tach Programming - CrimeStopper LC-1 Installation Instructions Manual

INTRODUCTION
This system has 3 methods of monitoring the engine running. Option #1 controls how the system monitors the engine
running.
1. Tach Reference Mode – Monitors Engine R.P.M. - Most reliable method, see Tach programming below.
2. Tachless Mode - Default. When vehicle is remote started, the battery voltage rate will go up because the
Alternator starts working. The Tachless Mode is adjustable in 1% increments thru Option 21.
3. Not Used.
4. Hybrid Mode – For electric motors that are computer controlled. This provides a 4 second crank output to
activate the start sequence on Hybrid vehicle. Don't use on vehicles with gas or diesel engine, 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 WHITE/RED 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, then wait for 5 light flashes and/or 5 horn honks.
4. Push program button once more. (You must get one light flash and/or honk after button is pressed.) This unit is
now at option #1-Tach Learning.
5. Press the #1 Lock Button on remote transmitter. The unit will read the Tach source and flash the lights and or
honk once for program confirmation. (On models without remote transmitters, press the brake pedal in this step.)
6. If lights do not flash for confirmation, then try another tach source or try the tach finder to locate another wire
