    Hey Anthony, again you come to my rescue. Thanks my friend, I appreciate and accept your offer to burn and send me the PROM. I have new 24-pin PROMs and will send you a replacement or two when I return your other gear. Just let me know if you need them right away...

    The .bin I need is...AKDX 87 G-M-R-V Van 4.3TBI 700r4.bin. It can be found in this thread

    http://www.gearhead-efi.com/Fuel-Inj...Information-42

    and is listed in input/response #5 (this listing is alphabetical).

    it may take acouple days iwill get back to you. if you want to program chips or run your autoprom in live mode I have a 288 with the socket changed I will loan you for a while. it reads the map at 95-96 kaps where it should read 99-100.

    Anthony, you are one generous and great guy! I appreciate the offer to loan me your modified 4288. So, did you soldered in a 28-pin socket? I have seen a thread in which Dave W describes that procedure and I am going to do the same. It just doesn't make sense to keep messing around with the 24-pin PROMs which are getting "harder than hen's teeth to find". I will wait for the chip you burn before doing "open-heart" surgery on my 7747. Thanks again.

    yes its not to bad if you know how to soider ,the article you read was it by eagle mark? I soidered the socket to the borad so I could close the lid. I have had 2 ecms go bad that was soidered that way, I got the adapter out of the first one the next time I tore it up removing it so next time I am going to use the zif socket first then if the ecm goes bad I can just pull the adapter.

    Yes, that is the article by Eagle Mark...too bad he passed away. So much information gone.

    Ah, ok on soldering and re-soldering...so, are you recommending I solder a ZIF into the board rather than a modified 28-pin adapter? I saw an article on the MOATES site where they soldered their G2 0.6" adapter for using 28-pin 27SF512 EPROMs. I think they also had a ZIF socket sandwiched between the board, 28-pin adapter socket, then the ZIF on top. It looked very tall and definitely could not seal the ECM.

    Did you determine what cause your ECM's to fail? The one concern I have is applying too much heat and frying some other components.
