Fuel Resistor

This snowmobile is equipped with a feature that allows the engine con-
troller to select the proper operating software based on the type of fuel
being used. See pages 62-63 for fuel information and recommendations.
Make sure the correct resistor is installed for your fuel choice as
instructed below.
PREMIUM NON-ETHANOL Resistor
To achieve maximum performance, install this resistor to the ECU fuel
designation connector when using:
• Non-ethanol gasoline with a 91+ octane rating
10% ETHANOL Resistor
This resistor must be installed when using:
• Ethanol gasoline
• MTBE gasoline
Whenever in doubt of your fuel purchase, use the "10% ETHANOL"
resistor as a safeguard.
The resistor is installed into the wiring harness on the left side of the
snowmobile just above the top of the oil bottle. To change resistors,
unplug the resistor and rotate it to align and install the appropriate plug
to the connection.
NOTICE: Engine damage may occur if ethanol fuel is used while the non-etha-
nol fuel resistor is installed. The check engine light may also display in
this condition as this could cause detonation.
