Hey fellas, I am about to get my OBD2 car programmed to a OBD1 PCM. PCMforless says it will give another 5-7 HP. I am hoping to get about 15 RWHP out of the PCM program, (I have the regular bot-ons and little stuff like that, with some gearing).
Also I already got a answer from this question on another forum but I am going to ask you guys too.
With the OBD1 PCM in my OBd2 car will I need to get 02 sensors if I get rid of my cats or add a y-pipe and headers. OR will I still need to get 02 sensors.
I would thank I wouldn't have to get any since the OBd1 cars didn't but I am just wanting to make sure. don't want to spend $80 on something I don't need.

 

I assume you mean O2 simms instead of O2 sensors. If you get the conversion pcm, it will just ignore the 2 rear O2 sensors. So you would be fine. All you have to do is swap in the OBD1 conversion pcm and thats it. Nothing else will need to be changed.

 

Just to give u another option...
