Throttle Position Sensor Optimization

[silverstreak]

Has anyone tried this? Its free so I might give it a try. Currently my tps shows 4.19 volts @ wot (using my aeroforce gauge) The write-up states you can adjust your tps sensor to 4.35 volts and enjoy the following;


The benefits of this mod:
Increased throttle response with optional idle adjustments
Better part throttle fueling - Power Enrichment reached sooner, aids part throttle KR
Ensure the PCM observes 100% throttle input at WOT
Slightly more responsive downshifts at part throttle

Its free other than my time so Im going to try it. Here is the link written by Will from Overkill

have you check the TPS percentage? it should hit 100% when WOT already.

Bio is right. Any auto performance or repair shop can check to see if its calibrated correctly. Heck even autozone's scanners might be able to do this.

The advantage of doing this without checking is that you are guaranteed that the PCM will see WOT. The disadvantage, you could throw the fuel map off causing issues everywhere but WOT.
