Auto Tach Programming Procedure
NOTE:
If no tach has been programmed and the START/STOP button is pressed, there will be no
start attempt and the vehicle will give 5 flashes.
If another Tach Programming is required, simply repeat the Auto Tach Programming
Procedure.
The Module stores the Tach setting, being AutoTach or Multi-speed Tach, until the
Module is reset.
ONLY if the Module is reset will a new Tach Signal need to be re-programmed.
This process can be carried out instead of the conventional Tach Programming Procedure.
1. Make sure all the connections are done properly and that the Module has been
powered-up.
2. With the Hood up (ground on the Hood Pin line), start the vehicle using the key.
3. Let the Engine reach proper idle speed.
The Parking Light output from the Module is activated when the vehicle starts and it
will shut off once the Tach signal is detected.
4. Press and hold the Brake Pedal until the Parking Light output from the Module
flashes 5 times.
5. Turn the Ignition off. At this point, the Tach setting has been programmed.
Table 5
Multi-Speed Tach Programming
The system is designed to read a wide range of Tach signals produced by newer Ignition
systems. No manual adjustments are necessary. However, you should go through the Tach
programming procedure every time a new Unit is installed.
1. FLASH the Hood Pin Switch (see on page 9).
Before the 20 seconds have passed.
2. Press and hold the Brake Pedal.
• Press the LOCK and UNLOCK buttons simultaneously on the Transmitter.
• The Parking Lights will flash 4 times.
• Release the Brake Pedal.
3. Start the vehicle and let it to reach regular Engine-idle speed.
4. Once the vehicle is idling properly, press and hold the Brake Pedal until the Parking
Lights flash 5 times, release the Brake Pedal: the Tach signal is now programmed.

Note: Tach jumper settings
Some new vehicles have a higher TACH voltage
threshold, which would fall out of the normal
TACH trigger circuit of the remote car starter.
Changing the jumper to TACH Threshold HIGH
will allow the module to properly detect the TACH
signal.
