Thank you and will do. Easy enough to remove parameters to increase the logging rate to see if 'something' shows up. Mainly i had the roughness and knock there to understand exactly where the issue was happening, where it wasn't, and if effecting all or just one of the cylinders.

Also, prior runs I did have AF3 disabled. Have been trying anything and everything to figure this out, it's been a LONG process. I will re-disable, eliminate unnecessary fields and re-log.

In regards to the WB, I have that thru TGV Right rather than the COM port: Column in the log is Wideband O2 AFR (TGV Right) (AFR)

Adise - I was able to get the tool to work... Using excel in the middle for the copy worked wonders. Its a nice tool.

Will advise, and thanks again!

@rsimmons1122 - Thanks again for the guidance.

After thorough testing with the high polling rate, still wasn't able to find anything conclusive. We ended up pulling off the AMS Intake Manifold, re-installing the stock TGV and Intake Manifold (Keeping the ID1050x, Rails, FPR, and SF Intake); redid the tune; and wow, I have a running car with no misfires. Taking it out this weekend for some long cruise stretches to get the MAF scaling just right, but after a week of commuting, LTFT are +/-3%.

I have some theories on the culprit of the source of the roughness (related to the AMS) but taking a break, enjoying the car, and zeroing in on the MAF Scaling/Comp for now, it's been on the lift for a LONG time.

May start a new thread on the AMS if others are interested.

Closing the loop on the thread, and happy to have the car back. :)

Thanks for the update! That's too bad you had to go backwards a little bit and take the manifold off. Glad you've got your car back though. Feel free to reach out anytime, I'm always happy to help.
