LT1 ECM 16188051 repair source?

**EDZIP** · 06-10-2015

Read, copied and changed the bin, then while programming the ECM & half way through...got the error communicating message, it did attempt again to install the bin but failed. Let it set for about 15 minutes...no luck communicating.

It's a backup ecm but would like to get it repaired..any recommendations?

Thanks

THANKS again...looking forward to trying this! I bought a soldering station a few months ago...now I get to use it!

Anyone here have the equipment to flash a 32 pin prom?

I do but I don't know if I have the proper adapter for the chip in the 8051. Look at the Willem programmers on ebay. I bought one for about $50 and they have several different adapters for various chips. Have you socketed your PCM yet? I have a Willem PCB50B. It uses a parallel port for the interface so you have to have a PC with a parallel port. Parallel printers are a thing of the past now. If you can tell me what chip you are trying to program, I may be able to program them for you. My LT1 transplant is going to be a future project so I haven't looked at what I am going to need yet.

i have the gear and would happily flash them for you, but im really far away from you. for the cost of mailing them back and forth, you can almost buy a programmer.

Just want to try it converting the PCM with the PLCC 32 Pin IC DIP Connector and 32 pin chips AN28F512 and AM29F040B. The latter is used in Ford applications.

Waiting for the PLCC 32 Pin IC DIP Connectors to arrive...bought extras if you might need a couple in the future to try. FYI: Tuner Cat will repair the PCM for $25 plus shipping - but just want to experiment.

Spotted those programmers on eBay and may still order one...need to research a bit more.

Revisted this site...if I'm correct he only removed and flashed "one" chip on the BLUE/GRAY side board? He doen't even discuss the other board on the BLK/RED side.

Anyone actually done this repair? Looks like only one eprom needs to be removed, flashed and reinstalled??????????

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.

Love the TL 866CS programmer..it was about $42 shipped on eBay. Finally got my 16188051 up and running after flashing the AN28F512 chips. My recent post:

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.
