U7146 - Can't read backup

[lundstedt]

I have a 2003 Mustang in here that we custom tuned last year and now are doing again with new heads. I restored the original backup to put updated crom in, and now when I try to load a tune, it trys to read ori backup, but says original tune not saved (-30). later message said it could be cause by having a performance tune already in it? Doesn't have a chip in it or anything.
Any ideas?

Go to options/troubleshooting/verification and turn it off, then try it again....

This worked to read the backup and program the custom tune we had for it, but now it has a crank no start

[mikel]

Sounds like something wrong with the tune....

Same tune its been running with for a year. It's a 5.4L DOHC navigator motor in a 2003 Mustang that we did the motor swap and tune in 1 1/2 years ago, we put new heads in it, ran it with this tune, but not now since i updated the crom to tune it, it does this?

Try taking a backup with the new crom, and make a cal file from the old tune.

Apply the calfile to the original backup and load that...

Tried it Mike, no success. Any other ideas? I guess I'll look for something other then the program, even though it ran fine with the new heads right before I tried the update. Did you run it by the other guys guys there?
