I've searched but haven't found quite the answer I'm looking for. If someone who has experience tuning these cars could chime in, that'd be great.
I recently purchased a catles DP and have a question about the rear O2 sensor. I am going to be running a tune that deletes the CEL for the O2 sensor, however I am wondering if I should run the defouler or not in case if I ever need to revert to stock tune for warranty work. I've heard some people say that the rear O2 only monitors for cat efficiency and I've heard other people say the rear O2 actually can adjust AFR.
I'm basically asking if there is any reason for me not to run the defouler with my catless DP. To be safe I'd like to run it in case I ever have to flash back to stock so it doesn't throw a CEL, but if running the defouler means that I'll be messing up my AFR, then it's probably better for me to leave it out.
Anyone feel free to chime in here! In for answers...
