We have temporarily put all tuning system/ECU sales on hold while we implement policies to comply with new EPA rules and enforcement actions. Restricted sales on ECU's and tuning systems will resume soon with the new procedures to be sure we comply with regulations.
The Throttle Position Sensor (TPS) measures the position of the throttle blade within the throttle body. The ECU uses this input to assist in determining the load on the engine and calculate fuel and timing requirements.
NOTE: The throttle position sensor at fully closed position should read .5 volts and at wide open throttle (WOT) should read 4.5 volts.
