Hey All, I am brand new to this forum, but I discovered something I had to share with you LT1 fellas. I wiped my 1995 PCM while flashing with Tunercat. I did the socket thing here:

http://www.mindspring.com/~amattei/flashfix.htm

Then got a little stalled with burning the AN28F512s. My trusty old eprom programmer was a little ancient and would not work. I then did some research and found this site:

http://sandeen.net/fwfix/index.html

I got on Ebay and found one of those Pro100 Intel NICs for $3.00, a few days later It was here.

I then had a hell of a time finding the programs the site was referring to. Intel has since made much higher level tools that were much smarter. After 30 pages deep in Google, I found some old version of the "fboot.exe". I popped the old NIC in an old PC with my DOS boot disk, and well, it did not recognize my Intel AN28F512 chips.

Not to be discouraged, I opened the "fboot.exe. in a hex editor and found where the tables were stored for the Flash "Device ID" I changed the Device Id for the CAT28F512 to Intel's ID. Saved the modded program, started up the old PC, and walla, it recognized the intel chip as a catalyst! Reburnt the chips and it worked great.

So........... for less than $10.00 and my modded program, you can reburn your chips.

Here is my version of the "fboot.exe"

Hope yall spread the word!!!

I'm guessing this is for the 93 OBD1 PCM?

Must be as that was the only LT1 with a removable EPROM chip. Well, there was the 92 LT1 Vette too.

Sorry for the confusion, this is for 94-95 PCMs. I edited my original post with more info. I think I could make the program work for 96-97s as well (AN28F010 chip), but have not tried.

Would be nice to have a full how-to write up on this ;)

How do you remove the EPROM from a 95 PCM?

I'm guessing this is what you would need to do if you killed your PCM with a failed upload?

I'd have to see someone I trust use it before I downloaded a zipped .exe file from a total stranger with 2 posts of which both are in this thread, no offence, but my mom always told me, "be becareful of strangers with candy!!", and "if it sounds too good to be true, it probably is".

Could also have something to do with my outlook on life, as stated in my sig!! ;)

Or, understand what the file is before you start flashing things :P

Besides, the little exe file is the simplest of everything.

Removing your EPROM memory chip with a heat gun and soldering on a slot...now that is a bit more dangerous IMO.

It looks like good solid info...for someone crazy enough to try it :P
