I have a 1988 Chevy 1/2 ton pickup and I would like to monitor the ECM data through the diagnostic connector while the engine is running. I understand there are expensive electronic tools to do this, but I was wondering if there is cabling and software available so that I can do this with a laptop or PDA? Where can I get more info on the net? I'm very computer literate, just not as they relate to cars.
Thanks! Dan
