Adjusting the Sensor

Important! Make sure the vehicle is disarmed. The shock sensor sensitivity can be adjusted by using a trimmer
tool to turn the potentiometer.
Adjusting the sensor:
1. Disarm the system, turn the ignition Off.
2. With the sensor mounted in its permanent location, locate the trim pot on the shock sensor module and
using a trimmer tool:
• Turn the potentiometer clockwise for increased sensitivity or
• Turn it counterclockwise for decreased sensitivity
Note: You can test the new setting by cautiously impacting the vehicle with increasing intensity while not-
ing the LED status on the shock sensor. The LED turns on for a short duration for small impacts before turn-
ing off (indicating a warn-away trigger). The impact level required to fully trigger the alarm is indicated
when the LED remains on for a longer duration before turning off.
Note: This adjustment cannot be performed using the remote control.

Initializing Virtual Tach (not needed w/hardwire tach inputs)

To program Virtual Tach:
1. After the install is complete, remote start the engine. The programming operation may require 3 cranks of
the starter before the engine starts and runs. Do not turn off the remote start if this happens, it is a normal
programming operation.
2. Once the engine begins running, let it run for at least 30 seconds.
3. Using the Remote, send the Remote start command to turn remote start off. Virtual Tach is programmed.
To reset Virtual Tach, go into the Reset and Deletion section of this guide. Virtual Tach cannot be reset with
the Bitwriter.
Note: Virtual Tach cannot be used in MTS Manual Transmission Mode. It is also not recommended for diesel
trucks.
