I am trying to track down a OBD interface/scanner manufacturer/supplier who has a interface unit that can decode my OBDI data via a serial connector.
No luck so far ...I would be very grateful if someone could point me in right direction ???
Thanks Mr PTOR...great links...you saved my a.se. I now know the difference between what is in my 13 year old OBDI truck and current OBDII. Ironicaly it seems I will be able to get live engine data and default codes out of my prehistoric ECU with a $30 cable and some freeware whereas OBDII requires big spend $ and many potential conflicts.
I got the aldl cable from aldlcable.com it worked minamaly (not very damn good) I returned it today!
You most likely did not have the software setup correctly or did not follow the instructions. My cable from aldlcable.com has worked great and I have hooked up to a number of cars with TTS Datamaster and EFILive, both free packages that are awesome. These GM OBD1 cars were far ahead of everyone at the time for data logging and tuning.
www.jegs.com abd search for Equus canodb 1 & 2 tool kit its $210 but its well worth it I have one myself it not only tells you the code but it also give you the definition of the code AND its upgradeable if you get a new vehicle. Its designed for GM, Ford, Toyota, & Chrysler/Jeep
