I have a 94 wagon with a lightly modded 94z motor and I'm considering converting it to OBD2 for diagnostic purposes. I don't have to worry about emissions So I think it might be legal to do the switch. Anybody have any expierence with this type of conversion? Am I wasting my time thinking about doing it? I just feel that I can get a better view of what the computer is thinking with just generic OBD2 data stream. My intention is to use tunercat to get my spark and fuel curves straightened out and PCMScan for my diagnostic work and data logging. I guess my main question is what kind of problems should I expect to run into? with tunercat you can delete sensors like rear O2's and outputs like the airpump right? I have little expierence with re-programming, but I feel confident enough in what I'm doing that tuning shouldn't be an issue. I just haven't decided if I should stick with the OBD1 in my car and get software that will interface with that as well as diagnostic software for OBD2 cars for side work. I would like to be able to buy only the one cable and two programs. What do you think?
