I have a 02 4.8 im using in my swap, I went to a very well known shop in my town to have the PCM tuned and vats removed. Well the HPtuners wouldnt tune it. He said i need a new one with my vin programmed into it. Has this happened to anyone?
I found a pcm on Ebay for $90 used and they prog your vin into it. Should i just get this and go back for the tune/vats removal?
Thx Any advise would be great!
whats the history of the computer? was it tuned before? it could be tuner locked, sounds like he couldnt right to it cause of this ?
you could probably ask in the for sale section and find one cheaper, just saying
May need a different ECM , I have a 03' module don't know if the same pm if interested and ill send u a pic
The PCM was stock and never tuned. Ill check the part # of mine an see if yours will work. Thanks!
Unless the PCM was bad the VIN should not be an issue. Just read the PCM, make change and re-flash.
Is the PCM the same as harness and engine?
03 pcm's are different than 02!
It's a 02 engine with the org 02pcm and PSI harness in 95 truck. The truck I got it out of ran and mine will start then die from the vats. I saw the hp tuner screen that said it can not download tune. I'm not doubting the tuner at all. Just if I should get a new or eBay PCM?
