2004 Mustang GT, cannot read file from car.........

Yes, I have the latest BETA, yes I have the EEC-V firmware, Support ticket #492089, I have provided infolog, degug, screenshots, etc. I was told to flash car back with read file, I cannot READ the file from the car :banghead:. This I can say, I plug MPVI3 into obd, turn key in on position, gather info, It gives the usual info you'd expect, click READ, it asks to turn key off for 3 seconds in which I do, turn key back on and what I have noticed the "theft" light begins to flash and READ fails. I will admit that I am a GM guy who has tuned a few whipple raptors, and some newer mustangs N/A and 4cyl turbo cars with no problems. But these older mustangs seem to be kicking me in the butt before I can even get started. Can someone provide some insight pleeeaaaasseee!

Might need to pcm swap to a supported strategy

If you haven't already, it's worth checking to see if there is a chip installed in the j3 port on the back of the pcm

I reviewed your ticket and the debug is showing a very specific error that is most commonly caused by a piggyback module on the ecm, I would suggest checking that first.

We've found the attached device to cause this error. Unfortunately it doesn't appear to be an issue connected to our hardware/software in this case.

You are correct Bill, thanks a million! Off and running now...

awesome, so glad to hear it!

Bingo!
