I have the minimun down to 0 % at about .995-1.000 volts on my tps. but i get about 1/4 throttle im getting 100 % i tried the self learn thing , but that didnt work .. for some reason i cant get the tps dialed in no matter what i do , anyone gone through this ??

 

Your FC is a S4, and as we all know S4 had an infirior TPS, but then again I have an S5, so I don't know how to solve your problem.

 

You get 100 percent because the tps is fully extended at about 1/4 throttle. That's normal on a series four.

Some people with series four turboii cars use the boost/pressure sensor in lieu of the tps.

 

I would also set your throttle LOW at 95-98 and your HIGH at 99. IF you want accurate readings then throw on a S5 TB and TPS and hook the narrow range to the ECU and the full range to the TPS.

 

i dont think s5 TB and TPS will work on S4...

 

Boost signal is the way to go on the S4's.
I even use it on my S5.

I cold air conditions the boost & fuel needs can get ahead of the throttle.

Pick up the signal at the sensor side before the FCD clips it.
I set low throttle to 40% which = about 0 PSI for crusing.
I set the high throttle to 90% which = about 12 PSI.
