I just put a GM 2 bar Map sensor (though it was a 3 bar) I had my Zdyne calibrated for a 3 bar and the car ran great. But when I would start it up first thing it wouldn't idle up at all. Now I set it up for a 2 bar and it starts and runs fine. But one thing I noticed is under the "Tune Wizard" section for Fuel compensation it's showing a 1 Bar Map sensor. When I go to change it a message says "This change is to be done uinder Configure menu". Which I have done. But it's doesn't change that part under Tune Wizard. I opened up a 2 bar factory map that came with it and it show 2 bar under Tune wizard.

 

Try saving the file after you chane it under the configure menu. then close it and reopen the file.

 

How come I can't change the map sensor at all? That section is grayed out.
