flashed pcm, now i cant read it or connect to it. need help!

[mustangtraitor]

Ill try to be specific as to exactly what i did.first off the car was tuned with a hypertech power programmer III to adjust for tires, and gears i removed the engine power tune.
i sent a friend a bin file for a 95 ta m6, not a copy of my bin.
I sent him a data log using tts datamaster
He modified the bin based on my data log
I scanned a copy of my bin using winflash before i did anything so i would have a back up.
I flashed the new bin to the pcm
started car fine
whent to data log and couldn't connect to the pcm data stream, tried reading pcm with winflash several times with no luck, tried flashing my old bin, no luck, tried freescan no luck.


I'm guessing the problem is the bin i sent him contains someone else vin# and i flashed a bin with a different vin than mine. or my data cable suddenly went bad?
I disconnected the battery for 30 mins... same story.


I plugged in the hypertech and all my old stuff was still intact, it wasnt showing the vin either. I removed all of it and then adjusted for my gears and tires and afterwards it shows my vin correctly.
so im not sure whats going on. at least the car runs and drives fine but i need to be able to read the pcm.
any advice or help would greatly be appreciated
