    OBD1 ALDL Cables

    $35 + ship for USB2.0
    $25 + ship for Serial

    USPS first class shipping is ~$2.50 or so every time i've sent one out to the continental US, Canada was ~$5 and Germany was ~$5 as well. but, choose whatever shipping method you like.



    anyways, these are MAX232(meaning proper, not the 2-transistor crap) ALDL to USB/serial cables, capable of interfacing with anything GM produced from ~1981-1995(with the only exceptions i can think of being the early OBD2 test vehicles, namely the 95 F-body 3800s and the 95 4.3 "blackbox" S/T trucks), and can read ABS, TCS, BCM, PCM, airbag modules, pretty much any module that GM placed in it's vehicles.

    obviously, you'll need software to translate the datastream into something useful, tunerpro RT is my recommendation, V5 if your laptop will handle it. i've been slowly building support for every module produced prior to 96, the only two "problem children" i've ran across so far are the saturn modules and the PM3 setup, neither of which seem to have accurate documentation. this could be remedied in the future, but is too complicated a process to explain in a group buy thread.

    since GM went with a proprietary DLC connector for most of 81-95 production, they're difficult/somewhat expensive to get ahold of, however ALDLcable.com has one that costs $21 shipped, should someone be so inclined. otherwise it would be intelligent to directly integrate the cables into the vehicle's wiring under the dash essentially adding a USB/Serial DLC port to your vehicle in addition to the OBD1/OBD2 connector. Penglii had issues with his Tech1 not wanting to communicate with the ALDL cable hooked up, however a simple rocker/toggle switch fixed this problem. i would think DIS/DIC and other modules on the ALDL line would need the same solution, however, no one has ever mentioned a problem with that happening?

    because ELM327 and knockoffs are somehow cheaper to buy than build.

    I'm in for USB. Do these cables use the laptop/computer for the +12v rather than the cigarette lighter?

    Slightly off-topic, do you have a thread somewhere for discussions of your TunerPro ADX? I've been using it for a while with my own "2 transistor crap" cable and have some questions...

    yes, no lighter connection, i personally can't stand that, especially when i want to have my laptop plugged in for logs. and slight correction, but it uses the USB +5V rail, nothing +12V.

    PM me, or make a thread on here or the TP forums, but i'd like this thread to stay mostly related to getting these out to people.

    also, i hate the 2-transistor circuit.

    And the benefit of having on or these also cables would he to accurately determine the pcm, bcm, abs and whatever sensor problems that come on through the "service engine soon" lights or "check engine" light ? I just want to make sure this does this before I say I'm in because my grand prix has only been able to be scanned by a snap on solus scan tool and those are quite pricey. This could be a nice alternative for me. Grandted I would be buying a laptop as well.

    yes, DTCs are one of the easiest things to check with an ALDL cable. live sensor data, statuses and a bunch of other stuff as well.

    for example: here is my modified A1(91-92 W 3.1) stuff:

    dashboard


    item list views





    history tables


    monitors




    all of which are completely customizable.

    Is there any difference between this and the one I have from ALDLcables?

    If I have any extra money this month, I'll take a USB cable because it will help you out...

    has your ALDLcable.com version started becoming flakey yet? mine started coming apart at the solder joints for the USB connector and caused all kinds of problems, so i cut the nice molded ALDL connector off and hooked it up to my circuit.
