LT1 ECM 16188051 repair source?

[EDZIP]

I have 97 OBD2 so don't know if it makes a difference. But the Eside (black connector side) on mine is the 28F512 and takes the 64k bin and on the T side (blue connector side) is a 28F010 150 and takes a 128k bin. And you are using a TL 866cs programmer and getting that to work? Wow mine is giving me errors.

I've been talking to CATS and im going to get a pocket tuner from transtronics... little spendy but is what they use and suggest so its the route im going. Better than buying more programmers that don't know if they work and trans units are known to work but 270 bucks but then I'm done buying others that may not work.

Just remembered that the 32 pin adapter only works if I put in a spacer..must be that the 28F512 sets to low in the adapter.

Before soldering the PLCC 32 Pin IC DIP Connector you need to remove the center so you can reach the contacts. That same center you remove and must replace after soldering works great while flashing using the TL866CS with 32 pin adapter. One I did that..no more errors..hope pic helps.

I had an old chip and was able to read that and able to bin file on either chip and worked. Just when I tried to put GM calibration from couple sources that it errors out.

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!

what programmer are you using? want to sell some PLCC-32 sockets?

[bigtoyz]

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.

Aw never mind read your post wrong....sockets not chips....yesterday was a rough day.
