Power Control Strategy
The standard Ski-Doo 1200 4-Tec models use an Ignition Lanyard with an
immobiliser function to power up the vehicle. If the Ignition Lanyard is
inserted, pressing the Start/Reverse Button on the left handlebar will start
the engine.
The installation of the Snowmobile Plug-In ECU solution still uses the
Ignition Lanyard but without the immobiliser function.
• Power is continuously applied to the ECU while the Lanyard is
connected. Tuning adjustments, log downloads, and ECU
configuration file downloads may all be performed without interruption.
• Power is removed from the ECU only by removing the Ignition
Lanyard.
Security
The Ski-Doo 1200 4-Tec uses an encoded Ignition Lanyard which is paired
with the factory ECU.
The Snowmobile Plug-In installation does not include the immobiliser
function. It is important to secure the vehicle when not in use for example
by removing the IGN4 device from the wiring harness. MoTeC dealers can
also assist in setting up anti-theft systems that will meet your needs if this
is a requirement that must be met for your particular application.
Idle Stepper Motor Setting (V3.52P or later)
If the Snowmobile shows stalling behaviour when the throttle is closed
suddenly, it may help to reset the throttle stop screw for a higher base idle
RPM setting.
The standard throttle stop screw has a tamper-proof cover and is very
securely glued to the throttle body with loctite. The screw can be very
carefully removed (warning - risk of breakage), and replaced with an M5
set screw with M5 lock nut.
To reset a newly installed stop screw
• Connect to the ECU Manager program on a PC.
• Observe the Throttle Position (TP%) in the Sensors list, or press
‘V’ for the Sensor View screen.
• Wind in the stop screw until the throttle position reads just over
zero.
• Wind back until exactly zero is shown.
