    LT1 ECM 16188051 repair source?

    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

    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.

    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.

    Thanks for the encouragement...might still be hope!

    The chip in PCM is the FLASH AN28F512, I also have a couple AM29F040B,,,been flashing them on a Mini Pro TL866CS. Have a Moates Burn 2..but the chips aren't supported.

    Will try your bins and double check the positioning. Soldering is OK verified by a test light.

    COULD you explain which is the T side? The eprom has one flat corner and appears to insert only one way?

    This Pcm has two flash chips. One on each of the circuit boards. They are AN28F512 Intel chips.
    You need to flash bin1 on the chip that goes on T-side circuit board and bin2 on the chip that goes on E-side circuit board.
    You need to identify which chip goes where by trial and error or find pictures to identify sides.
    If you flip chips Pcm will not fry so don`t worry.

    Well that's my problem..I was only half done:-)

    My grandson just arrived for the weekend so may be a bit before I get to the other side. BTW when I attempted to program either of your BINs got a message something along the lines that the parameters were not correct....but I'll try again when I have more time.

    Thanks for getting me back on track.

    The full bin is 128 kb size. It is used in tunerpo and tunercat that way.
    Each chip contains half of the full bin.
    Bin1 is first half (64kb size), bin2 is second half (64kb size).
    I guess there is a problem with the bin size not set correctly in the programmer.
