Throttle Position Sensor Adjustment
S&S® Freedom® Performance Tuner has a Throttle Position Sensor (TPS) adjustment feature for 2003-2007 model year motorcycles. If the
•
motorcycle you have performed a calibration download on has a lean or rich condition the TPS can be adjusted to target a desired air fuel ratio.
Most motorcycles will not require a TPS adjustment unless the idle screw on the throttle body has been moved or the throttle body has been
cleaned.
Throttle Position Sensor Calibration
Special Tool Requirements for Throttle Position Sensor Adjustments on 2003-2007 Victory® Motorcycles
•
a- PV-45410 – Victory Exhaust Gas Analyzer Kit. Picture 14.
b- Volt meter (Fluke 73 or higher recommended)
1– Install the Victory exhaust gas analyzer kit to the exhaust system of the motorcycle you are performing TPS calibration on. Picture 14 illustrates
the Victory exhaust gas analyzer kit.
Note: Some exhaust systems have a removable lambda sensor plug in the exhaust system that the lambda sensor can be threaded into; others will
require removing one muffler and installing the exhaust gas analyzer tool between the header pipe and the muffler.
2– Connect the lambda sensor cable to the lambda sensor and volt meter.
Note: Do not connect the lambda sensor power leads to the battery at this time, the sensor may heat unevenly and reduce the service life.
3– Secure an exhaust extraction system on the exhaust pipes or take the motorcycle outside before starting.
Never run the motorcycle in an enclosed area without a properly functioning exhaust gas evacuation system connected to the exhaust
•
outlet.
Engine and exhaust components get hot and remain hot after the engine has been shut off. Wear protective clothing to avoid injury and
•
make sure no cables or wires are touching engine or exhaust components.
