Is he referring to ODBI or ODBII? I have no interest in this unless it works on my car.
...and at first, I thought it was a thread about the USB/Bluetooth ODB readers that are floating around for $20 on eBay. If anyone is considering them - don't bother. I've bought 3 different ones. All highly rated in reviews. NONE of them work. If you're into your own diagnostics, save yourself the hassle and spend the $150 on a decent OBDII reader from a reliable automotive parts source.
