I have a 2003 GMC C4500 with a 8.1l & Allison trans. This is the error message I get when trying to tune it.

17750


How could I tune a 2001 gm truck with the same engine but not this one. HELP PLEASE !:unsure:

I've ran across this before. First make sure efi live is up to date. If so, just do as the screen says. Email it to support. It just means the os in that pcm isn't in the list yet. Normally takes a few days but they will send you the calibration file for it and your good to go. I see this a lot with 4 cylinder stuff.

The other time you can get this error is if you have wrong controller selected when trying to read. Your screenshot shows LS1B controller selected, does your vehicle use this controller?

But first make sure your software is up to date, we are constantly adding support for controllers.
Try installing this version: https://forum.efilive.com/showthread.php?24830-Update-Oct-28-2014

Do Help->About and see what the build version is.

Yes, the only controller I see is a LS1B. That is what mine looks like. Is there another that looks the same ? the PCM IS 411

You should re-install the software (actually, download the Oct 28th software and install it).
