From all the sites I keep seeing, it looks like an OBDII data logger can read any OBDII car (using the proper adapter). It doesn't seem to be brand specific (except the plug). This makes me think that an OBDI logger will work on any OBDI car (if you have the adapter). Someone has got to test this out. We just need to find someone with an OBDI logger and test it out on our cars. I'm going to try my best to find someone with a logger to let me try it. If it works, I am so going to get the pocket logger (Palm III's are cheap on e-bay and the software is cheap too). I encourage anyone else to try to borrow an OBDI logger too...Leon?
