I could easily buy one of the handheld units, but for two reasons:
1. I am cheap.
2. I am a modder.
I would rather have something with more functionality... specifically a cable that I could hook to my laptop and get all sorts of neat data.
As far as handheld units go, Amazon has an Actron CP9135 for a good price.
I'm a little more confused on the PC cable issue. Carplugs.com has parts and preassembled cables. Only caveat is that on one of their product pages, they recommend an $80 interface which ""isolates your computer from the vehicle's electrical system. Plugging the cable directly into the PC may damage the serial port."
I don't want to damage my vehicle, or my serial port. But this guy has a homebuilt cable which apparently works well as-is. Hmm.
Anyone have any experience with OBD-II scanners or software? Schematics or suggestions?
