Appreciate the info and the files...I believe I'm working on the T-side (gray/blue).

Just wanted to let you guys know that after many hours of trying to repair a 16188051 that flash-crashed I got it up and running. The desoldering, soldering in a socket and flashing the chip was the easy part. I tried many (many) bin combinations and the one that finally worked was the combination above by 96lt4c4.

First flash attempt and PCM is back on line and easily flashed with my final bin.

Thanks all

Hey EdZip,
This is fantastic! I am lucky to have found this thread. Not two hours ago, I bricked my '95 LT1 PCM while flashing with WinFlash. I have never had a problem flashing with anything else. Today I decided to try WinFlash and it killed it.
I cannot communicate with it anymore. The LEDs on my ALDL adapter won't even flash anymore. They used to go wild as soon as I plug in the laptop.

I was going to send it out to the TunerCat people. They say the can fix it for $25 but, I see here you were able to bring it back from the dead. Would you mind it too much to paraphrase what you did? I am not foreign to electronics, so if you want to get down to techs, I am fine with that.

I am not trying to get out of the $25, I really want to learn how to do this since I have the feeling this is going to happen again. I want to get the EEPROM on a ZIF if that is possible and buy a dozen of of those little suckers just to be on the safe. :)

Could you please share the knowledge?

Thanks.

BUT bookmark this thread...it has the (2) bin files that worked. As a matter of fact the repaired PCM is still in the car working great. If you run into any problems...just send me an email.
