Back when I used an OEM ECU I used to use this to read and clear codes. What I'm offering is a Palm Treo 680 that has the latest version of the Dyno Scan installed and the cable that connects it to the car. I do not have a Treo 680 Charger anymore. You'll need to get one. The Treo does not have a SIM card, with one you could even use this as a phone. 50 Bucks shipped in the US for it all. I'll help with how to connect.
