    Astro 4.3L V6 TBI (1991)

    Hi there GearHeads,
    I was sent here by some nice people from the AstroSafari forum.
    I saved an Astro (1991) after it was abadonned in the field for more than 6 years. Pretty succecfull as the van has passed technical examination and I've already driven 3000km since.
    But it's not (yet) in top condition.
    ecu is trowing tons of codes that I would try to read out with the paperclip method :)
    Meanwhile I built a ALDL to USB cable (with arduino chip) that works with WINALDL
    at least I get data-flow (rpm /tps ...)

    But now I'm stuck .
    I cannot get TunerPro or similar linked up?
    What could be wrong ?

    What .adx / .ads file are you using with TunerPro RT.

    If you have the 1227747 ECM you can find the .adx file here:

    If you have the 16144288 ECM you can find the .ads file (which needs to be imported into TunerPro RT) here:

    What are your TunerPro RT preference settings for Data Acq. / Emulation?
