Default TPS calibration problem

I'm trying to calibrate the TPS on a customer's 97 Miata with a MSPNP. It currently reads about 10% at idle and 70% at WOT. I have gone through the TPS calibration box, retrieved values for 0 and 100% throttle, and hit OK. However, it doesn't change anything. The software still shows 10-70 instead of 0-100. I have tried saving a copy of the file, cycling the power, re-sending the ECU file, etc. I've tried calibrating it with more than one file, multiple times. Am I missing something?

Have you tried adjusting the sensor itself? That's what I ended up fixing mine.

Yes, but that would make one of the extremes even worse. The ADC numbers for lo/hi are about 26/182 or something like that, and they move smoothly from one end to the other. The problem seems to be that the MS isn't actually storing/changing the TPS calibration when I set it.

does your throttlefactor.ini match the values you see in MT? maybe the file isnt writing?

It sounds like you have, but make sure you close MT and reopen after calibration.
