TPS range meant to be set at 0.45v or 0.50v for closed throttle position? (zero % tps)

Post by B18CR-X »

Is TPS range meant to be set at 0.45v or 0.50v at closed throttle body position???
in help, some places say 0.50v and others say 0.45v, thanks again

Do not use voltage, use the percentage reading in the software.

I set the volt first by ajusting the actual TPS then I use hondata to set read closed and open positions

DO not go by voltage. Instead, use the read function in SManager to adjust it as close to 0 as possible.

Don't understand stand what you mean by, use the read function in SManager.
So, I attach my laptop to my PCM, click the datalog button.. what next after that??
do I click on the sensors button, and check what the TPS percentage is at???

with the key switched to ignition, (Ignition on car off)press F10 to datalog, go in parameters, TPS tab, go down to "scale TPS", press MIN reading % button with TB close, then push pedal all the way down and press MAX reading % button. Upload and save calibration.

then double check that with Throttle Body closed, the data log is showing TPS throttle angle % is at "0 %"
and Throttle body fully open it shows TPS throttle angle % is at "100 %"

it's because people assume that you've gone through the software and read all the help files before posting on here, most people don't like to *babysit* new people, personally I RTFM first and read and read and do some more reading before I ask for help, usually the answers are out there sure the answers can be a bit convoluted in the help files but hondata isn't the only company out there with a tuning software, they are all quite similar and all the software's have their own help files for reading if you can't find what your looking for here. the nice thing about hondata is that it doesn't matter what your TPS voltage is set to really because the software reads the exact voltage and sets the ECU to 0% for min throttle and when you go wide open you might be 0.5 volts higher or lower then OEM but then just press that read button on max throttle and it resets it to 100%. now if you put a stock ECU back in you would have to set the TPS position properly because stock ECU's don't have the read function obviously. :)
Let's not make assumptions, please leave as much detail as possible!
