After the above I then zeroed out my CL to OL Transition table and it seemed to help but still need to figure a way to smooth my AFR.

Did you log to see when it's actually in open loop? i.e 8 vs 10 in CL/OL status. Could also be the front O2 acting up.

Also you have a bunch of areas pulling timing, including in the higher loads, have you tuned the timing table yet? If not, I would recommend addressing the the knocking areas first.

Hi ShinjiML,

I did address the knock as stated above, my total timing is pretty smooth and conservative. But regarding logging CL to OL status, the during the wavy parts in the beginning it displays 8 for CL.

Regarding the sensor, it possibly could be but hopefully not the case.

Any elsewhere to look at in the ROM?
