Hey all,

I'm trying to figure out what cable I need to log my '08 Impreza's ECU. I think the CAN protocol is being used... though I'm really confused as to the distinction between CAN-bus and OBDII. In any case, I'd appreciate if someone could direct me to a USB adapter cable or something similar I could use for data logging (no intention of flashing or tuning). Since this is becoming a long term project, I'd also be interested in trying to design a cable and the associated chip logic by myself (though I'm having a really tough time trying to find any good DIY resources since I don't know which kind of cable to design!)


edit -- noticed this is sort of in the wrong section, if someone could move it to the parent forums id appreciate it
