Thank you Bali! I will post the logs, I will be driving for 30 minutes on Saturday 2 ways, that should give more than enough data.We just updated the DME software on OP’s car to the latest. Then started the engine and let it come up to full temperature. Here is what I saw using INPA:
I verified the AT->MT coding was correct (his 2001 325i has ZCS) by making sure both IKE and EWS had modified GM part of the ZCS.
- pre-cat O2 sensors were very responsive at cold start
- idle was rock solid at 700 RPM
- both STFTs were excellent (staying between -1% and +2%)
- MAF value was correct at 11.5 kg/hr (3.2 g/s)
He later verified the pre-cat O2 sensors are not crossed-connected.
I’d like to see an OBD Fusion Diagnostic Report at hot idle after a few days of driving it normally.
So far driving 10 minutes to and from work, it seems all good.
I will also check the manifold caps and post-cat sensors on Saturday to make sure all is in order.
