I've used an 1994 LT-1 engine in my "LoCost 7" project car, everything is done, built, so now it's tuning and optimizing. There are two O2 sensors for this engine, my understanding is pre-cat and post-cat. I'm running the engine with headers to straight pipes down the left and right side of the car so there is no y-pipe. This means the O2 sensor can't get a read from both the left and right cylinder banks. I originally placed the precat O2 sensor on the left exhaust and the post-cat on the right exhaust but that's obviously not the way to do this.
If I just use a single O2 sensor and delete the post-cat sensor via a flash, then I'm only going to be reading half the engine, far from ideal but good enough? Is the only alternative to remove the O2 sensors complete and tune accordingly? There is absolutely no room to install a Y pipe, that's for sure.
Anyone have any suggestions here?
The attached pictures really have no purpose on the above question, I just thought you'd like to see the car and engine bay.
