Stage 2 91:

Stage 2 91 ACNSorry I know this log is a bit messy as I didn't stop the log in time, pull is in the beginning of the log.)
https://www.bootmod3.net/log?id=5f61...0b43415b7e0108

timing looks a lot better with the ACNI map. Also there's something wrong with the fuel pressure on the first log. It looks like a roller coaster, that will probably have something to do with the crappy timing, as well as the gas.
Perhaps someone else with more knowledge can comment, but isn't 17psi boost a little low for a stage2 map?

Im not even sure what I'm looking at here. Im still learning. I know there are parameters that I need to turn off for next time. Is there anything jumping out at anyone that I should be concerned about? I'm currently running Bootmod3 stage 1 E30. My charge pipe, down pipe, and intake should be here any day now. Then, ill be switching to stage 2 E30.

Thanks for any info you might be able to share with me about this

Looks very good. Just be aware than Stage 2 E30 will require you to get your mix right. It's a little more sensitive than the Stage 1 E30 tune. But looks like you have it good now and timing is clean.

Your fuel pressure is dipping really low. It says you're running Stage 2 93, is that correct?

Yea that is correct. I noticed it dropped fairly low and picked back up the last 1/4 of the pull. What could be the cause of this?

** I was looking at my previous logs when I had a major timing issue and I noticed the fuel pressure dropping at the same moment as well. Not as this severe though.
I even put in a ticket with bootmod3 to help with timing, and they said everything looked good?

What is a good safe zone for rail pressure? If it dipping down to 2000psi is that okay?

[Glemm1970]

The fuel cut will kick in at 1600psi. Up to 2000psi is not good, but the car will keep going.

[Nik440]

could someone look at my Log?

I did a pull in 3rd gear and something just is not right. There are lots of timing corrections across all cylinders. And the throttle dropped around 3000 RPM. I think there are several problems.

I run Shell VPower here in Germany, that's around 100 ron. And the current map is -> stage 1 98ron

The car is completely stock, but has a muffler delete!

New logs are up for Rev 19. We've turned things up quite a bit, car feels very fast. I don't think I'll run any more boost than this, I'm probably right at the limit of safe power, or maybe a couple toes over that line...

Logs look OK to me, some smallish timing corrections on C2

https://datazap.me/u/tnilson/pure800...og=0&data=3-21

Oz you mind running another VD graph for these logs?

Can anyone check these logs for me, I'm in California running MHD stage 2 with a 1.5 Gallon e85 mix with the rest 91 because MHD advised me to do so.
Akropovic downpipe and dinan cold air intake is installed as well.

You need to ideally log from 2500 - 6800 in 4th gear. WOT, Transmission in manual with traction off.

Use the MHD auto logging function.

I did.

[M140_BCS]

Both logs don't pass 5800 rpm...

This is a Stage 2 91Oct tune with 93Oct/99RON fuel to compare against yours.

You can expect small timing corrections lower down the rev range but as you head towards the redline they should be minimal.

Damn you hit 32 psi and 250 load with a fully open throttle, at 3500rpm looks like these rod's are pretty strong! Also there is a concerning drop in your HPFP at that point, which is expected at that load.

But seriously you need to get that looked at, if you do over boost like that (5psi above target) it should close the throttle to control the load, I would not feel safe without any throttle action to rescue me form over boost

[Cobra358]

BM3 Stage 2+ map, I think it looks pretty good, other than it is not holding boost target at high RPM, any thoughts? https://www.bootmod3.net/log?id=5f88...90c63d0074eca0

[dawidd3]

The log looks very good, the serial turbocharger is not able to keep 21.8psi to the end.

Hi guys! I’m not with F30, but with B58 engine.
Trying to make my G30 540ix faster but it’s seems to be a long long road to the goal)))
So, my 540 is now with VTT GC turbocharger and Dorch Stage 2 HPFP. Wedge sent me second revision of 98 Ron map, after I flashed xHP Stage 3 to get around torque limiters.

https://datazap.me/u/akhmed/wedge-12...og=0&data=3-19
https://datazap.me/u/akhmed/wedge-12...og=0&data=3-19

Can’t understand why the rail pressure jumps that way.
Sent logs to Steven. Hope he fix it.

Hey gang. Noob to tuning here. Old timer when it comes to BMW. On my 4th one (including e92m3 and f83 m4). Would one of the learned take a look at my log and lmk if anything sticks out. Stg 1 BM3 93 oct; afe CAI; NGK plugs gapped to .022. TIA

[FastSleeper]

Hey guys! Completed my first data logs and wanted to field some feedback. Please let me know if anything sticks out. I'm running Stage 1 93 and these were 4th gear runs from 2500rpm to just about redline. Any help would be greatly appreciated. Thanks.

Is a HPFP drop on initial WOT a normal thing after a DP install?

I just added a VRSF catted DP and went Stage 2 91 with BM3. I've never seen dips before like this during WOT pulls.
