LT1 ECM 16188051 repair source?

[EDZIP]

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.

Update: Installed the EPROM socket and flashed the chip..still get:

ERROR Unable to communicate with PCM

Did give it a try! Oh Well

BTW: If anyone has a bricked 16188051 and would like to try installing a EPROM DIP connector let me know I have extras.

Try flashing this bins.
They are split for e and t side.

Before programming the chips make sure you erase them.
After the write is complete, test read them and make comparison.

If the chips are flashed correctly and there is still no communication, there is a chance you flipped them, or there is a bad solder. Double check all the solders with magnifying glass to be sure.
Stoch chips are very durable and should last 100000 write erase cycles.

Can I ask you what programmer you`re using and what type of chips.

Also t side is responsible for communication. You can still manage to connect with blank eside chip, but the engine won`t run.

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.
