https://datazap.me/u/wrxtobimmerguy/...0?log=0&data=3

I thought this tuner was one of the best tuners for the platform. Do you have any recommendations?
Again just my opinion:

I feel like that tune is on the bleeding edge of being safe. I would run an OTS map for your setup until you can get it fixed.

Other tuners I recommend are listed in the description of this video depending on what tuning platform you use. I am tuned by OdinTuned and very satisfied with the results.

I wasnít happy with timing corrections and riding the knock limits even with the ots tunes and the drivability wasnít great.

Kirill at OdinTuned managed to correct these issues and fine tuned it to my conditions and fuel quality and itís very nice to drive. I would also highly recommend !

Tonight I ran my first log since making changes to my '16 340i. I'm a bit concerned about the cylinder timings.

https://datazap.me/u/kevmk81/log-162...37-38-39-40-41

Car:
xhp stage 1
mhd stage 1 93 octane
er catted downpipe (installed within the last week)
awe midpipe and axle back
FTP intake pipe (stock airbox with afe dry filter)
vrsf charge pipe
Shell 93 octane
38k miles
Spark plugs changed roughly 2k miles ago with NGK iridium. I believe they are gapped same as what the old ones were.

It's really strange 23 C is not high ambient temperature at all and Shell fuel is a reputable fuel.

So my guess is there was some residual heat already built up. I am actually purchasing one of those AFE scoops - hoping that might bring down the IAT.

small timing corrections are common with the B58, i saw already a lot of simular posts with the same issue. solution is to use a higher octan fuel ( 95 , or use 3-4 liters ethanol at full tank for more octan )

Almost 4 degrees timing correction on all cylinders around 4500 RPM is not that small.

Also the timing delta for knock adaptation should be closer to zero.

It is very hot today, and an ambient temp shows 35.5℃
Nevertheless I tried to make some log today.
My car is 2017 340i RWD.
E.R catless downpipe
Akrapovic evolution line link pipe and exhaust.
CSF heat exchanger
K&N filter in stock air box
NGK94201 with stock gap
Genuine ignition coils: Eldor
TU_HPFP
M sports LSD
Maybe 98ron fuel that is sold as 'high-octane' gasoline in Japan

MHD stage2HPFP 98ron beta3 from Bigboost
xHP stage3 ver.1.7 with torque limiter off

I would like to understand the log especially about timing correction and
frequent torque limiter interference.
I appreciate your advise!

Your cylinder 1 is pulling a lot of timing for some reason. if the tune isn't complete then let the tuner keep working on it.

Did you mean run it more rich? (more fuel more cooling). Would you say the AFRs are reasonable or should I ask my tuner to make it more rich?

What is your altitude(elevation)? Looks pretty high?
That hybrid seems maxed out at quite low boost

No I meant more lean. Richening AFRs improves cooling. But ethanol/methanol burn cooler than gas, so you can run it more lean in some instances without damaging anything.

It's probably fine. I'm assuming it continues to drop as you get towards redline. But again consult with your tuner.

Hey guys, getting going on e85 tuning for my big turbo. Tuner thinks port injection isnít spraying, but when i compare STFT to other tunes like pump gas i dont see a difference. How do my logs look, what am i looking for? I have a motiv reflex connected to hobbs switch so i know i need to make sure the switch is working and check wiring, is there a place to look for comprehensive info on the subject?

Hi all, so this is a 4th gear pull from my drive home today.

https://www.bootmod3.net/log?id=610b...729b1db9302d9c

I'm wondering about the boost overshoot and the effect that has on the HPFP and throttle position?

If boost overshoots, does the throttle close some which results in a lower rail pressure. I thought the waste gate took care of too much boost.

Rail pressure target remains constant, so I'm trying to figure out whats happening here. Is my rail pressure drop the cause of the throttle closure?

Running the Dorch stage 1 HPFP and BM3 OTS stage 2+ E30.

I'm likely at higher than e30 but not higher than e45. I don't have an ethanol analyzer yet and the ranges for e85 are stupid wide at the pump.

Any comments would be appreciated.

log looks good. throttle closure is DME controlling the overboost. HPFP dip is signal that you are over limit of the pump, especially since you are overboosting and requiring more fuel than anticipated at those RPMs. i wouldn't be concerned about your dip though. pretty small dip if you ask me. you're still over 2k psi. i've seen dips into the 1500 range without significant issue, but also not ideal...

the HPFP is mechanical and can generate more pressure with RPM.. so it is common to be over limit at low rpms when the surge of boost hits.

you could decrease ethanol content to help out your HPFP. your timing is perfect, so definitely margin to decrease ethanol.

you could also not change a thing, because i would be very satisfied with a log like this.
