If you are intending to read a odbi 8192 data stream I think u need to send some bytes to the ECM to get the 8192 baud data coming from the car. Excuse if this isnt about aldl car ecm communication, i'm looking for a way to interface my 18F4550 to a 95 Holden Commodore series II VR so that I can read the stream from the car (i beleive it's 22 bytes) in an 8n1 stream format...

if anyone is working on a usb 8192 odb1 interface using a 18F4550 I would be overjoyed to chat with you about your progress..
