Default TPS mod update

i was reading about this small mod about the tps setting for better throttle response they say idle 0.75 volts max and WOT 4.35 so i got mine to .70 and 4.35 but i clould have gone to 4.41 what does it do if you go more than 4.35

the correct setting for my ser 1 i believe was 33-41 mV. i had one out of adjustment, much like ur describing in ur "mod" and once the pedal was to the floor, the throttle percent went through 100% and then dropped to 0%. and the engine would die if i kept foot on the pedal.

so from my experiance, when you go past the full setting, it went to zero.

ur tps is one of the most critical sensors used to time ur spark with ur fuel delivery.(well at least on ser1) i would imagine that to be true on ser 2 as well.

yikes. Mine is at .29-.31 at idle and 4.11 at WOT. I think ill swap my spare in and see if it'* numbers are better and tweak the one that'* closest to "perfect". Good topic.

first off, those specs were for my series one. im not certain yours is the same mV setting.

but more importantly, dont just change it. if it is out of range you can more than likely just adjust it.
