Data Bus Interface Port
This 4 pin port is used for Flashlogic Door Lock and Transponder Databus
Interfaces to communicate with the vehicle's Databus. When using the DBI port to
control the Flashlogic Door Lock and Transponder Interface modules the
following options may be available. Please refer to the D2D (Data to Data)
function list available per vehicle on the tech service web site.

Feature Descriptions
Tach Programming
The unit will not operate unless tach is programmed or tachless option is
turned ON. If an attempt is made to start the vehicle via the remote start without
first programming tach, the unit will flash the parking lights 7 times indicating tach
has not been learned and stored. If the tach rate is not properly programmed to
the specific vehicle, the unit may not realize that the vehicle is running in certain
instances and reengage the starter motor.
The Remote Start unit will learn the tach rate of most vehicle's single coil, multiple coil
packs, or single injector. To learn tach:
1. Turn the ignition key to the ON position.
2. Press and release the valet/override button 3 times.
3. Immediately turn the ignition key OFF.
4. Press and hold the valet/override button, then start the vehicle using the
key.
5. When the unit senses the tach signal, the parking lights will begin to flash.
6. Allow the vehicle to settle to a normal idle speed.
7. Release the valet/program push-button switch. The parking lights will stay
on solid indicating that the learned tach signal is stored and the unit has
exited tach learn mode.
NOTE: If the unit fails to learn tach rate due to an improper tach connection or a
poor tach source, the parking lights will not flash. To correct this situation, locate
and connect the PURPLE/WHITE wire to the proper tach signal, and then repeat
the tach learn routine.

the last 8 times the vehicle was started with the key.
DBI Port - Monitors the vehicle’s tach rate through an interface module
connected to the DBI port.

is activated to after the engine is running may be less than 0.5 volts.
6 - Crank Time: Preset output times for the PURPLE starter wire.
1 Second 0.8 Seconds 1.5 Seconds 2 Seconds 4 Seconds
7 - Crank Average / Crank Time: The length of time in which the remote start
will crank the vehicle’s starter.
Crank Average - Determines crank time by averaging the last 8 times the
vehicle was started with the key.
Preset Time - Preset starter output time. (see crank time)
8 - Gas / Diesel: Selects engine type and delay time for the starter output wire
during remote start activation.
Gas - Gasoline engine, no delay for the starter output wire.
