Need PCM Replacement Advice / Is my chip fried?
First a little background on the situation:
2001 Excursion 7.3 with Banks chip, intake, exhaust and wastegate.
I do a lot of towing enclosed trailers with race cars in them and that is about what 90% of the trucks mileage are spent doing. Towing last year the transmission let go. Buddy is a Jasper dealer and gave what is supposed to be an upgrade 4r100 through them for cost, a little over $2000 along with a 3 year, 100k warranty. Tranny was shifting hard into third under a hard load which I didn't like so I took it back to him and he called Jasper and they sent out another transmission. Put the new trans in and it's still shifting hard, Jasper said it must be something going on with the ECU causing the hard shift and to have the dealer reflash it. He sent to the dealer to have it reflashed and they tried to reflash it (with the chip in it) and said it wouldn't take it and now the truck won't even start and they said it needs an ECU.
Apparently they say my truck has some uncommon ECU in it so there are no used ones to be found anywhere.
Are the more common 2001 7.3 ECU's compatible or do I have to go back with the same part number? Is my ECU junk because they tried to flash it with the chip in? Is the chip now junk?
The part number on my ecu is 1U7Z12A650FSA
Thanks for any information, input or advice you guys can offer!
