Input on datalogs please

[llowlife]

Just went to cobb stage 2+ fmic aggressive LT. Never run a data log before so I am still learning. Everything looks ok to me but I could be missing something. Both these are 3rd gear pulls. Step tranny with Alpina flash and LSD if it matters. 93 BP fuel

Engine mods

Tune
Catless DP
CP with Tial
RB CCV
Drop in AF
7" FMIC

Hopefully these links will work. Just click on whatever you want to view underneath the graph. There is a chart underneath the legend if so desired. TIA

Anything I should be logging. Anything that I can get rid of? I went off the cobb recomendations and am maxes out at 22 items I believe. I will need to research some of this as BMW is a different animal with targets loads etc.

I'm running stage 1+ right now and debating if I should go stage 2+. How much of a difference did u feel going from 1+ to 2+? I also have step with aplina flash but no LSD

The difference between the 2 was quite noticable in the seat of the pants. 99% of my driving I don't even register positive boost numbers. I run stage 2 for the remaining 1% of the time and on the track. I plan to do an e30 tune after this learning curve on the 93 octane.

I have never run the 91 tunes.

Looks pretty good.

You can ditch LPFP and HPFP requested as well as Cyl1 timing cor. Then log load vs. actual and TPS.

That might help determine why you're seeing the dip in your boost at 4400 rpms or so.

[Allen@MOTIV]

Log looks pretty good. Timing drops out at the start of the pull but quickly recovers. Boost control is less than ideal and you're probably seeing some throttle trimming as a result(hence the dip in boost at 4.3Krpms.)

Appreciate the time to help.

Here are 2 more logs with tps and loads.

The dip is still there and it does look like there is some closure on the throttle. It is happening right after what appears to be "too much boost" as pointed out to me by Allen at HPF?


Again Thanks for any time given

Help with the tune or the Dumbass part? Many have tried and most have failed on the character reference. I am debating if this is something I want to do myself or farm it out to someone like PTF.

I want to learn how to do it but it is something that takes a lot of time to learn well. AM I ready to take the time or not? I do know that I am not done with mods yet so to pay for something that may change the tune later? Not sure of that either. Decisions,decisions...........
