PCM Programming - Now PCM Dead!! HELP!!!
Ok, now I have a big problem.
Using TunerCAT I downloaded my Flash and made a small change to the cooling fan temps and tried to write it back to the PCM. It established communications, then erased the PCM Flash, then I got an error message. "Invalid message Format" or something similar. I clicked Ok and it said retry was successful. It proceeded to approximately 50% then I received another "Invalid message" error. This time it aborted with no other message. Then my cooling fans turned on and I knew the PCM was dead. I tried to send the Flash image again and Tuner can't establish communications!!
This is not good. What options do I have now? I have my Flash memory on my laptop, how can I load it?
:cry :cry :cry

Re: PCM Programming - Now PCM Dead!! HELP!!! (Atok)
to the best of my knowledge the pcm is gone. you will need to send it off to have the flash chips changed out, for new ones. i have been down that road many times. check the camaro forum there is a guy who can put sockets so you can change out the flash chips if it happens again. he goes by "mad wolf" ion is a stand up guy.
an after thought would be to build a desktop programmer. there is a schematic floating around here somewhere. "glock '94" i believe has built one. i found this to be the most reliable way to program. there seems to be too many variables to flashing through the connector inside the vehicle. i went through about three new pcm's before i discovered that the laptop inside my vete was not a good way to program my pcm....
ion@soltan.net is the way to contact ion about pcm repair..best of luck

Re: PCM Programming - Now PCM Dead!! HELP!!! (drive it)
I was using the Windows version. I didn't know they had a DOS version. I would defintely prefer the DOS version. What's the name of it?
I think I'm going to socket my Flash chips and use my EPROM/Flash writer to make changes from now on. If I ever make another change. All I wanted is my fans to come on a little earlier. :(
