Any problems with log?

I am new to tuning and just added the following to my 2014 Z4 35i with 120,000 miles:
VRSF DP
VRSF 5” stepped FMIC
VRSF DCI
1 step colder spark plugs
New coil packs
Outside temp 87 degrees, 100% humidity
Are there any problems with my log? I am running MHD 2+.
Thanks

Thats a clean log. There is nothing outstanding. Why are you asking?

 

[WayEast]

I am asking because on my first run at WOT after I programmed to MHD 2+ I received a CEL code 29cd. I cleared the code and it has not came back on other runs. Just marking sure everything looked ok with the log.

29cd indicates a missfire. Keep an eye on it and try to use the highest possible octane fuel only.

EDIT: What Index do the fuel injectors have?

Sometimes you can get misfires under high boost if your plugs aren’t gapped a little tighter. 0.022 tends to be what most people run with a more aggressive tune. What are yours gapped at?

Mine are gapped at .022. Even tried going back to new bosh plugs still same code. Tried different octane settings, swapped coils, plugs, and injectors same code. If I run at MHD stage 2 no issues.

That’s definitely a mystery, maybe a pro-tuner could figure it out. If you’ve tried all of those things and nothing solves it, it’s so hard to tell.
