    I managed to find and purchase a true relic that *may* make tuning of ECUs as olds as 92 possible.

    found a Toshiba processor development kit for auto manufacturers.

    time to find a windows 95 computer to run this hieroglyphic software.


    this is the tool toshiba provided developers

    good news, bad news.
    good:
    1. data is and can be extracted from the ECU (any 1990+..maybe even slightly older).

    Bad news:
    The chips are true OTP w/ mask rom. completely impossible to reprogram. You can get data out, but can't write back.
    Toyota used one time programmable chips. I have read they can be erased with Xrays only.
    However creation of a daughter board could be possible.

    this is a challenge.

    There was a company early on that removed a chip and retrofitted another on on the first gen ECUs. Any idea what they were doing and how effective it could be?

    Here’s a link when Gadget writes about E.L. Prototypes.

    OV-I hit you up about a year ago asking you if you're going to develop something for the 4th-gen Lexus RX350. It's very similar to the 3rd-gen situation. I would PM ya but you look overloaded in there.
    Back on subject I'd be another fan for my 2001 Tacoma.
