TPS Problems
 

Ok i purchased the TPS from wolf but i'm having similar problems that i experienced with the old TPS. I set it up with the min/max feature using the handcontroller, but the resolution is just too small. What i mean is the 0% throttle is 4.4volts and the 106% is 4.49. So it works fine with no throttle and with full throttle but inbetween its just not accurate at all.

Any ideas?? The other TPS was like this as well. I checked with some base wolf base maps for other cars and most TPS's are setup with a min/max voltage of 1 - 4volts. Oh and its not the ecu because i'm borrowing a mates v400 while mine gets upgraded and its doing the same thing on both. There just doesn't seem to be enough resistance to drop the voltage.

I will check the output signal with a multimeter and see what it reads. Maybe i have it wired incorrectly.

You are missing the earth to the TPS One end is +5 volts and the other is ground you have a missing ground!!!

ok i'll check the ground wire maybe it's cut somewhere.
Thanks

Ah i can't believe it. I had the ground and the signal wires wrong :wallbash:
Working perfect now. My old one would work fine too if i had it wired correct. I just wasted $70 ah well.

Your Welcome, I have learn from experience just like you have. :)
