STEP 1: Change Option 2-10 to setting 3 - No tach sensing.
STEP 2: Process complete – there is no further programming required other than adjusting crank time
when necessary (see below).
Adjusting Crank Time: To adjust minimum crank times, refer to Option 2-12. To help ensure successful
starting, the system will automatically add additional crank time to the 2
nd
and 3
rd
start attempts. In
addition, there is a built in “Smart Resting Mode”. Traditional tach sensing is still highly recommended for
colder climates.
Timed Crank Setting – CM4 Series V.37 or CM5 Series (Automatic
Transmission Only)
Option 2-10 setting 4 provides a timed 1.5 second crank for the remote start sequence. This option just
cranks the vehicle for 1.5 seconds and assumes remote start has completed. This option can be used for
GM and other vehicles with built in anti-grind systems.
Green/White Loop
This loop wire determines the transmission setting. The default position (uncut loop) is for manual
transmissions. When the loop is cut, the system will be ready for automatic transmissions. In the default
(manual transmission) mode, the system must be set up in Reservation mode prior to the vehicle being
able to remote start. IMPORTANT: All warranties or claims are void if a controller with a cut loop is
installed on a vehicle with a manual transmission.
Reservation Mode for Manual Transmissions
To remote start a manual transmission vehicle, the system must first be set up in reservation mode.
Reservation mode is designed to prevent the vehicle from remote starting while the transmission is in
gear.
Installation Requirements
1. The vehicle’s door
triggers must be connected to the control module. Prior to making final
connections, test the factory door triggers to ensure that they are functioning properly.
2. The vehicle’s emergency/parking brake wire must be connected to the control module. The proper
vehicle wire usually provides a negative (-) trigger while the emergency / parking brake is set.
3. The vehicle’s clutch must be momentarily bypassed while the remote start cranks the engine. This
momentary bypass simulates the clutch being depressed. For complete details on how to wire a
momentary clutch bypass consult your CompuTech program or contact our technical support department
by calling 888-820-3690.
IMPORTANT: Do not install a remote start in manual transmission vehicles with convertible / removable
tops and in user’s vehicles that leave their windows down. Firstech nor their authorized dealers will
assume responsibility for improper use or install.
Activating Reservation Mode
STEP 1: St
art the vehicle with the key. Place the transmission in neutral, remove pressure from the
pedal brake, and set the emergency/parking brake.
STEP 2: Remove the key from the vehicle’s ignition. The vehicles engine should remain running even
after the key has been removed. If the vehicle does not remain running, check the emergency / parking
brake connection.
