N54 IJE0S Tuning Help

[traktorfaktory]

Hello,

I am learning to tune my N54 335i xdrive MT coupe with 68k miles located in Utah (5,000ft elevation) using Tuner Pro. Car is FBO with stock turbos, upgraded FMIC, index 12 fuel injectors, recently replaced spark plugs gapped to .2, 6-month old coil packs, Inlets, new o2 sensors, walnut blast 25k miles ago.

I was using MHD Stage 2+ and noticed WGDC after PID is lower than base value. https://datazap.me/u/traktorfaktory/stage-2-mhd?log=0&data=3-23

I am trying to squeeze some more performance out of the car using Tuner Pro and among everything else, looking to fix WGDC. I understand that base value should be less than after PID, but not sure how to do that. Less WGDC adder on 4.8 seems to be a bit better more adder on 4.9, but still doesn't look good between 3500 -4400 RPM.

Another Item changed between 4.8 and 4.9 is increased load target per gear. Given the over boosting, I figured that I would just raise the load target to maximize boost. boost ceiling is set at 1.55 in 4.9 vs 1.5 in 4.8

Would you please give some advice on how to adjust tables in Tuner Pro to not only improve the WGDC values, maximize quick spool, trouble shoot timing corrections above 3800 RPM and anything else I may be overlooking.
Thank you.

better to go with a 3 bar map sensor and due custom 3D map scaling, move all the load target and boost ceiling up and out of the way. For your issues with PID either keep the stock tables and just adjust duty accordingly so if PID is trying to pull boost, lower WGDC, adding adder is just going to increase duty. It might be best to put adder to zero and just be about 10% under target then add adder back to fill in when needed. Also based on your log add about 3-5% scalar from 3500rpms up your fuel was still good but I would clean it while you are there.
