Yes I've used the search button, I've scoured the threads and haven't found the answer to my specific question.

Little bit of background info, the car is a 1995 240, but has obd2. I'm a california resident and legally pass smog (would like to keep it that way).

So I'm currently in the process of doing a conversion to manual on my 240sx, and I'm wanting to use the auto ecu (for now at least). Now I know that doing this will throw codes for obd2. My question is, when they go to do the non obd-2 test (since it's only required on vehicls 96 and up) will the codes from using an auto ecu still come up since they're doing an obd1 test and not obd2? Will the vehicle fail?
