But to answer your question I screwed up...
They change with position. At WOT, 4.26 volts it was 53. at .53 volt TPS it is 00 but inbetween are like 1d, 4f, OE and some other numbers.

Thanks to Greg for getting this project done! We now have an ADX that shows TPS in Volts and Percent!
New ADX file will be in the 1227747 Information thread. It also now has a working Vacuum gauge and readings in list view!

No problem, I went ahead and ran the numbers. for a max tps of 4.5Vthe equation becomes:
(X -25.6) * .488281

That's good because I checked my TPS at Wide Open which is about 1/16th to 1/8th inch past throttle blades being wide open and only got 4.45?
When I looked at my MAP voltage reading, key on, engine off it was 4.45! So just because theres a 5 volt reference it looks like it does not use it all!
With the new equation I get 93.9% at 4.26 volts where my WOT is!
