1994 - OBD1 or OBDII ??


I am working on a project with a 1994 Jeep Grand Cherokee. I was wondering if anyone could tell me where I could find software to pull trouble codes out of the ECU. Does anyone use Autotap or a similar program on their 1994 GC's?? Any help would be appreciated.

BTW, the end goal of this project is to have the jeep drive itself from LA to Las Vegas.

thanks for the info. What we really need is some type of software program that displays the inputs to the ECU. (Coolant temp, intake air temp, speed, rpm, etc ) Some of the more sophisticated software also allows you to map the fuel/spark tables / fans on temp/ and a variety of other adjustments.

I know of software that exists for my camaro, and was wondering if there is a similar program for the jeep? Thank you!
