Hi, can someone please review my logs and let me know if anything looks off?

4th gear pull:

3rd gear into 4th gear pull:
https://datazap.me/u/jklad/3rd-4th-6...d?log=0&data=1


I'm seeing some post shift-timing corrections on the second map that sort themselves out, but I believe post-shift corrections are normal, hoping someone can confirm.

Also, there's an tiny rpm spike in my first map, not sure what that's about, maybe the tires broke loos for an instant or perhaps drove over a bump?

Both maps are after replacing my bank 2 o2's, and rewiring my dp fix with solid quick-disconnect connections vs. electrical tape lol.

car is 2007 335i 6MT with 150k miles; Cobb Stage 2+ drive map; New mitsu turbos, new coils and plugs, index 11's w/ 60k miles, vrsf fmic and dp's, DCI.

Thanks in advance!

Looks like new turbos are spooling great. Is there a way for fuel or lamda adaptation in cobb?
The short term fuel trims are quite high approaching 34.

STFT are sky high...reset adaptations then pull another log.

You should not be driving daily with the DP fix installed. That should be used for just passing emissions as it can alter fueling.

Ok I will fully disconnect the dp fix this weekend.

Should I then reset adaptations and drive for a bit prior to logging at WOT? Not sure how long it takes for adaptations to "re-adapt"

Yes I can reset adaptations, at some point I gotta make the move to MHD...

Yes.

I finally have an updated log - we believe that my rear o2's had been reinstalled incorrectly after the turbo replacement, leading to wacky rear o2 codes and fuel trimming issues i've been experiencing. We switched their locations and also fully removed the dpfix from the ecu.

Can someone please take a look at this new log below and let me know if it looks more on point in terms of the fuel trims, or anything else?

3rd gear shift into 4th:

Cobb stage 2+ drive map, same car specs as above.
Thanks!

Looks pretty good. Timing corrections are typical, there is some variation between Bank 1 and 2 AFR's... could be early signs of a leaky injector on Bank 1. I wouldnt worry about it unless you start getting missfires.
