Hello everyone,

First off, thank you in advance to all who take the time to read on and reply

The car:
335xi 2008 sedan (E90) automatic
Running PetroCanada 94 octane

The mods:
JB4 G5 (obviously)
DCI
******* DP
2nd *** delete
Charge pipe with Tial BOV
Alpina flash

Problem:
when driving (normal driving) the trims are all over the place (from close to minimum to almost max) and the car is somewhat sluggish and hesitates when accelerating. When putting the foot to the floor, the car first hesitates, then acts like a rocket (this is most noticed during low RPMs).

Problem persists with or without traction control and DSC, so it's not tires slipping...

Did some little pulls but can't do a proper pull from low to high RPM on 3rd gear because I don't have any places to do that safely (winter, race tracks closed and police everywhere). I have changed the sparkplugs about 6000km ago, changed the air mass sensor in the charge pipe (dead and gone, replaced with new one), cleaned my DCIs

Fuel trims really bother me to be all over the place like that but I have some suspicions on PWM, FF, timing and maybe boost.

I have included a couple logs for your enjoyment

Would like to know if I can do anything to solve this or make it less of a sh!t to drive...

Thank you

Sooo, nobody wants to take a look?

Terry? Anyone?

Will need to see better logs but I'd recommend setting menus 11 and 12 to the default settings and see how that does first.

What kind of logs you need? I can't really go 150kph without risk...

What are the default settings for 11 and 12?

[Steve @ BMS/Fuel-It!]

The default settings can be found in the user adjustment tab setup example.

I see menu 12 has a default setting but menu 11 doesn't...

So it's like playing darts in the dark

Ahah, it's been years since I opened the PC app... only been using the mobile one for so long since it's more convenient and didn't remember those default to be there!

Will check this out soon and see if it helps
