    Update...

    FYI to anyone following this thread we got the TL 866CS to flash both chips for bigtoyz.

    Yeah that is quite confusing why yours did it and mine wouldn't till I was able to read the chips then I could write to them
    once I pulled the files off the chips. But I think I'm going to invest into the programmer that's CATS use and suggest
    just in case something comes up. I put it out there on few sites I'm on. If anyone needs help that their old chips
    are still use able. Just send them to me to reflash them. I've worked out a deal with CATS for factory stock bins for 96-97 LT1 bin files with your VIN.

    I was lead to believe once pcm was bricked chips were shot. Had I known that isn't true. I would have had about 12 sets laying around. Just need to erase them and reload the files. 28F512 chips are the harder ones to find and more expensive ones. I paid same amount for 5 of the 28F512 as I did of 60 of the 28F010 150's and yes there are 2 speeds of chips 120's and 96-97 use the 150's

    Personally I have spent sooo much time fussing with the LT1 PCM, they aren't worth it. But alas, I keep on....

    Doing 3 PCM's tonight....

    I have tons of sockets if someone is trying to socket their PCM. I bought a few hundred 10 years ago and used 6 or so of them since!

    He uses the TL 866CS and works good for him, I did get mine to work when He sent them back to me and I pull the files off and I can do other chips also. But Im going to a different programmer when I get the $270 saved up so I don't have issues of doing RAW data.

    But do you the data put on the chips? If he doesn't respond, I have some chips and how many pairs do you need? PM him cause I don't want to take away business from him and if he doesn't I have his email or I can sell you what you need.

    my email is bigtoyz@itctel.com if you need his email, I'm not going to post his with out knowing if he wants it out there or not.

    Can anyone give me some type of procedure for flashing the chips with the minipro tl866? I just purchased one after socketing my pcm. I have both of the bootable images needed to flash to the chips, but every time i try i get "ERROR! Address: 0x000100 Buffer data: 0x18 Verify: 0x00"

    Make sure your look at post #29 of this thread.

    Do a search on you tube and it kind of walks it through it. It works for Ed as you've read and I have same issues as you do. Ed is a great guy maybe he will do for you what he did for me. Send him your chips and the files for each side. And once you get them back I bet you will be able to read them and burn them. And once you pull a copy off save them as your master copy. And they are reusable so DON'T throw them away. You can erase them and make them full usable again. If you need a second set I have a pair if Ed doesn't want to sell a set. That way you can have a back up ready if needed, and them just reload them with master set.

    once your done with your tune you can just slip them back in the programmer and keep a recent copy of what you've done.

    Thanks bigtoyz, Ed was actually able to solve my problem. I used a spacer in the minipro socket as he suggested and it worked like a charm, no more error messages!

    They are posted in this thread. To easy identify which side is which. On eside there is one big chip labelled d84g. On tside there is the knock module. Or connectors color blue/grey tside; red/black eside.

    i think the only difference is the AN is the automotive verision with a higher temperature range. i'm sure the other one will be okay. if you're really careful de-soldering the old chips you can just re-use those too
