I personally keep (FAA) Bit 1 (Rear O2) enabled with a 1 in the cell and disable (FEA) Bit 15 (P0140 Rear O2 No Act) with a 0 in the cell. I'm hoping that it will keep from throwing any P0140/P0420 codes since I'm catless. Whether or not this bit disables the P0420 code is not in my knowledge base however from past experience, I have seen a relation on other platforms. I don't have a rear O2 sensor anyways since I somehow managed to misplace the sensor during the test pipe install...... might as well disable that Bit.
As for fuel trims, I'm in NKY, so our weather is constantly changing. As a result, I do run the O2 Sim without the Rear O2 disabled in order to keep fuel trims. This is the best way to do it unless you decide to drive your car in a climate that doesn't have major air temp changes. Our Winters are cold and our Summers are hot..... keeping LTFT helps me more than having it disabled.

Thanks! Yea, I keep the bit for rear o2 on. I have a rear o2 sensor, just no cat. I'm glad I turned it on because the shop that tuned it scaled the injectors incorrectly. Fuel trims shot up to -12.5% pretty quick. They are under control now, but I also had to adjust the fuel maps to compensate.
Thanks!
Thanks!
