For example, The LS2 MAP sens is different from LS3. If you try to run an automatic file w a manual trans, you need to wire in a TCM to get the correct speedo voltage. Otherwise the ecm reads 12 volts,and sees 158mph all the time. I bought a PSi computer for an LS2/T56 build a few years ago. I asked for an LS2 manual file from an 07 corvette. I had several issues, and upon pulling the file it was for an 08 corvette. 6 months and many hours on the phone, It never got fixed. The told me they don't have any LS2 files. He assured me they changed everything needed in the tune for an LS2. Finally I bought a blank ecm and had the LS2 file loaded on it. Every single problem was fixed. This has happened to others and in another build of mine. There are so many variables, and some have ways of getting around it. I'm just trying to help simplify. Oh, and the newer ecms don't like to be overwritten with a different file lol. Have a couple that we bricked experimenting

      Do you have a pic of HP tuners for that file screen? I just don’t remember there being one for manual transmission to turn on or off reverse lock out.
