    Something I found on the net about your other programmer. https://www.eevblog.com/forum/repair...1v-with-tl866/

    I show 2732 to be 25v programming and 2732a to be 21v programming, 27c32 is 12.5v. Maybe the link above will help too. I have multiple eprom programmers and I still use my 2 PocketProgrammers and 2 PocketRoms(emulation) the most with my GM stuff :)

    If you don't mind, post your 2732(x) .bin file and I will burn to stuff I have here and check. Do you know where the checksum is located in your bin?

    I am quite surprised your 2732a shows a 12.5v programming voltage, maybe china bs? I have never seen that in real life with a 2732a. 2732a's are generally 21v for programming. They can be READ with much less voltage but eproms are very picky about programming voltage.
    I agree, it is surprising to learn 2732b chips require 12.5 volts (actually 12.75), however GM used 2732b chips. GM typically sourced 2732 chips from National Semiconductor / Texas Instruments and Fairchild ( https://deramp.com/downloads/mfe_arc...0NMC27C32B.pdf ).

    Google drive does not like my winXP lappy, post the 4k 2732 file here, I would like to figure out the checksum. It's not your issue but I am curious.

    I have used LH2.2 Editor for modifying the fuel map. I would assume that this also recalculates the checksum as necessary? You can find the driver on my Google Drive: https://drive.google.com/drive/folde...d0P3d1ORRASfS5

    Best regards
