Default 20 M550 CTS intake log check 3-5 - 04-13-2022, 07:09 PM

Good evening!

Curious if someone would mind looking at this log for me. From my last post Iíve learned a little more about BMW and looking at the data. Outside of my timing drop Iím curious if all else looks ok? This is map 1. Iím not sure I fully grasp the IGN numbers. Whatís do the decimals next to them dictate?

Started at about 3k WOT to 120 (on a closed road).

Iím running 93 here in Texas. Was about 60 degrees.

Unfortunately I do notÖ. Guess one of the things Iím unsure of. Next to the avgign number. What does the .7 and such represent? I believe my stations here are currently switching out their winter blends.

Also, not sure if this is normal. Iíve got a CTS intake on it now. Iím getting what sounds like flutter at WOT. Iím assuming itís the wastegate doing itís thing. Boost seems fine.

Thanks for taking the time to help!

This is exactly what was asked for- I believe. So confused by the throttle closing. This is a light Map 6 with max 3lbs added.

Please upload another log, but in map 1, and traction control completely off if it wasn't already.
