so i havent done the bup stop mod yet, but i checked the TP value woth efilive for my car, and at full throttle it marks 100%, but when u look at the throttle body you can tell its not opened up all the way. if i do the mod, will it set a SES light?

 

It will only throw a code if you go over 4.7vdc. I'm not familiar with EFILive so no help there unfortunately.

 

Look at this it is a good write up on the subject;

well, i guess ill just measure the voltage then, instead of going by efilive. thanks for the help

 

I would think that you could file the holes on the throttle position sensor and retard the tps if you did throw a code

 

It does make it easier to make TPS adjustable.

EFI Live has TPS Position and TPS Voltage. The position always learns itself to 100%... the voltage is what you're lookin for. My stock voltage was 4.3 and I ground down to 4.6. The PCM always figures out what 100% throttle is. Good luck.

 

ahh, ok theres my mistake then, i was going with position, not voltage (i didint know it learned itself to 100%). thanks for all the help/links, guys!
