Icon1 HUGE timing corrections - 05-14-2019, 10:52 AM

Hello all, this is my first post on this forum so I apologize if it isn't formatted correctly. I have an F30 335i Msport with an EWG and I'm running JB$ map 5. There is a huge timing correction that is occurring that seems to originate on cyl 1 and then hits the rest of the cylinders. I only have 67k miles, but it is the original plugs. I'm running BP premium fuel. Attached is a log of the pull. My initial thoughts are fouled spark plugs but I am concerned with the fuel trims and suspect it is a bit lean. I am also not hitting target boost.

I plan on changing the spark plugs this weekend. To my knowledge they are original. I just purchased the vehicle a few weeks ago. Any help is greatly appreciated.

I see that you haven't received a response yet so I thought I'd share the little info I know about this question. I was told by someone at BMS (I think it was Terry) that cylinder 1 on the logs are the target, so ideally the other cylinders should follow cylinder 1. Also the numbers are the actual timing and not corrections. Unfortunately I don't have a lot more to share.

I'm only able to open the log in excel, not the JB4 app. Did you manually modify the CSV at all? Can you re-upload?

Something is wrong with the CSV file and I can't open it in the JB4 interface. Make sure you are not opening or modifying the files in any way. Add another file here.
