I know there is a ground and two signal wires. What color wire on the tps to what pin on MS1 V3.0? I'm working with a Series 4 turbo.

I'm only getting 30% full throttle. is this normal or should i just get a new tps and try it again? My setting are 0 and 85 in the calibrator.

 

No, not normal. Does the reading go from 0-30% as you push the throttle? Even the narrow range TPS will give you 100% after about 1/4 pedal travel.

 

Yeah, full tps travel like your saying is about just a bit over 1/4 pedal reads 30%. This weekend i'll just get a new tps and see how it pans out. Also i'm experiencing erratic signal behavior from the old tps from the 10% mark to the 30% mark, it just jumps around and around 7% it will drop to 0% and if i press just a tad bit more it will pick up around 10% like it has a dead spot or something.

I just got this car and it's raged out very bad, i dont doubt the last owener did any work to it.

 

If you are in for some fab, grab a generic GM or Ford TPS and use it instead. That way you get a brand new standard TPS that is full range.
