CM7 Master Guide
STEP 1: Change Option 2-10 to setting 2 - Alternator sensing.
STEP 2: Test wire and make connection. The stator wire is found at the vehicle's alternator. Change your
multimeter to DC voltage before testing for this wire.
A. At rest, with the ignition off, the stator wire should test 0V DC.
B. Turn the ignition to the run position. The stator wire should now test between 4 – 6V DC.
C. Start the vehicle with the key. The stator wire should now test between 12 – 14V DC at idle.
STEP 3: Process complete – no further programming is required.
Tachless Mode – (Automatic Transmission Vehicles Only)
Tachless sensing is an alternative engine sensing mode. It does not require a connection to the vehicle other
than the main ignition harness. Note: due to the delayed peak charging found with most late model
computer controlled alternators, this feature may not be reliable.
STEP 1: Change Option 2-10 to setting 3 – Tachless Mode.
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 2nd and 3rd 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 – Automatic Transmissions Only
Option 2-10 setting 4 provides a timed 3 second crank for the remote start sequence. This option just
cranks the vehicle for 3 seconds and assumes remote start has completed. This option can be used for
GM and other vehicles with built in anti-grind systems.
Advanced Tachless
Advanced Tachless is a no connection feature (2-11 option 2) that can be used as a more reliable "tachless"
or no wire connection option. In order for this feature work the no connection "voltage sense" feature (2-10
option 3) must be selected and no tach signal input on the main control module should be present. With
Software update CM7v3.4+ advanced tachless will enable a voltage check for the Assumed running
engine sense option (2-10 option 4)
Assumed Timed Crank
Assumed Time Crank is the last feature of Option 2-10 for remote starting. This is intended for vehicles with
built-in anti-grind feature or vehicles that do not have a 12V Positive starter wire at the ignition harness.
This option will send a 3.0 second crank signal to the vehicle. This option can be used on vehicles with built
in anti-grind systems or Push To Start (PTS) systems. With Software update CM7v3.4+ advanced tachless
will enable a voltage check for the Assumed running engine sense option (2-10 option 4)
