NEWER LOG AND T6.0L L92 heads, L76 test and tune
This is my first crack at tuning this setup, I have an issue with the pcm not going into closed loop by itself, I had to turn it on in the VCM Controls to get closed loop, I am not sure yet why that is happening. The scan is with the clsoe loop enabled. Please take a look for me and give me some pointers if you can. This is a short drive but the first time its been on the road with the new motor and trans.

You have a problem in Bank 1. You car goes +25 in the LTFT's and 30+ in STFT's. You also have a ton of misfires. or reported misfires. Something is up, that may prevent the car from going into closed loop. Forcing it is not normally a good idea especially if there is a problem on one bank. You O2's may not be going "ready". Cant see it with your configuration file in the status bits section.

I did get a P0200 code, I am going out to look at that now. I did not get any misfire codes. I did not get a check engine light with the code. It is check in the DTC table. thanks for the feedback

Ignore the log and tune above. P0200 was set because #3 injector connector had a pin partially backed out so the injector was not getting a ground signal from the pcm. I will log more data a post it here. This engine runs very strong on a test drive today, it should be fun once tuned correctly.
A new tune and log file are in the first post
