Can someone take a look at my log and give me their thoughts on why it's running so lean?

I did a baseline data log of my car before putting a tune on. I noticed it's running a lot leaner than I expected (13.5-14 AFR) and I saw some timing corrections on all cylinders. I got new plugs and coils so maybe that will help with the timing but what about the AFR?

Thanks

Looks like a normal stock tune. Thats about right for what the stock fuel map targets at that load and rpm.

Hopefully the new plugs/coils will help corrections. What octane fuel were you running?

[ZeroCool]

Thanks for the feedback. I was running 93 octane but the gas might be a bit old since I haven't been driving much these days.

I want to go to MHD stg 1+. I have a fmic and cone filters only but I just did a bunch of maintenance. I'm wondering if throwing a gallon of e85 in when running the 93 octane stg 1+ map is a good or bad idea.

Sure will help a little with knock. It shouldn't be needed though, see what the next fill up looks like with fresh fuel

Whats up everybody. Been on here for a while, but never really post much. I just switched over to MHD and am looking for some help with my first log ever. Car is a FBO 09' 335xi.
I just finished changing over to index 12's, new O2 sensors, new spark plugs, not to mention a whole lot of maintenance items. I don't know how to read the log, but it looks like at the very least I have a boost leak?

Let me know what you think!

So im totally new at this and i just recently flashed mhd stage 1 on my E90 N55 335. I did a log on the highway WOT and wanted to know if there is anything wrong. It seems like its making corrections on 3 cylinders which I dont think is good and its also not making full requested load. I have BMS intake and Cobb CP. Any info on what could be the problem and how serious it is (am i gonna blow up my car or seriously damage it with this tune).

I could use some advice regarding timing corrections.
They dont seem to be consistent, some pulls are really clean.
But when they do happen, they are often pretty bad (about 6 to 9 degrees).
Mostly only on 1-2 cylinders.
I also have the standard AT post shift timing corrections now and then.

Here is an example with a 6.7 correction during WOT, and then a 9 post shift: https://datazap.me/u/kulixo/log1?log...7-8-9-10-11-22
I'm more worried about the one during WOT.

I'm running full E85 (verified quality) and NGK's gapped at about 0.20.
The engine head was recently completely cleaned, so there is no build up in the valves.

You're overboosting a ton on every shift. Look into possible stuck wastegate. Also the AFR should jump up after tip-out way faster.

I did plugs and coils myself when I first got the car. I brought it BMW recently and they said I should check the plugs and coils because there is the tiniest sputter barely noticeable at all but that’s what they suggested. Idk of that has anything to do with it. Is it bad to drive my car if the turbo is stuck like that.

Hi! So recently I've been trying to datalog my car ever since I've installed a stage 2 LPFP and running an E50 mix. Have to say I don't know how too much other than BARE basics, but I don't see any out of the ordinary other than some minor timing corrections. However if anyone of the gurus here can take a look I’d appreciate it cuz the car feels fast but not 420+ whp fast, and a stock n55 m2 was keeping up with me too I did see that target boost was only at 14-15psi, seemed low, is that normal for the Stage 2 map? Thanks in advance!!

The boost does seem a bit low for that map? But I haven't run that. I got 16+ on 1+E30? You need that FMIC badly then go 2+ and you should see much better power. I'm getting 18.2 psi target on 2+E30. I should upgrade my LPFP and try E50 but its going to have to wait. Besides it runs great right now.

Stage 2 without IC runs less boost thus it looks normal. Your IAT is really high so you must get an upgrade IC and flash a stage 2+ E50 map, it will be faster and then you will be around 420whp if all is good.

Boost and timing look horrible... Boost/vaccuum problems and bad gas...

It's all on this forum and on MHD website.

Ill go over all my vaccum lines and give everything a double over.
My spark plugs took toasted, could that be the issue?
Or Could it be tune related also?

Thanks

Would anyone care to take a look at my log running an e30ish blend on a stage 2+ map mods are

Vrsf dp catback and chargepipe, tial bov, ,motiv flex fuel kit, mishimoto intercooler,1 step colder plugs, delphi coils, 3.5 bar map sensor, spool stage 2 bucketless lpfp, and bms dci

[Godzilx]

I'm having crazy timing corrections that seem to happen randomly. At first I swapped plugs and coils on cyl. 1 and 2 but I'm still getting ridiculous corrections up to -8.7

Running an E30 mix on mhd stage 1+

Any insight whatsoever would be greatly appreciated

https://datazap.me/u/godzilx/plugs-a...24&mark=35

EDIT: I went and added some more E85 but it's still acting strange. Ridiculous timing corrections on cylinder 1 on one log and 4 &5 on the other

Hi, first of wanna say thanks for takin the time to look at it. I was looking at some of the other Stage 2 datalogs and some were targeting 1-2 psi higher so I was concerned. Everything else looking good though? The cars oil temp regularly sits at 240-250 degrees Fahrenheit. FMIC Is coming and I'll post updated logs then.

[Paliator]

Hey all. I recently went stage 2 plus and got the VRSF 7.5 Competition intercooler. However ambient Temps are around 65° F and my iats are around 110. I'm disappointed in the results from the intercooler. What could be wrong?

[dyllan12]

I'm still learning how to read log and I was hoping someone could look over this to see if theses are good

https://datazap.me/u/dyllan012/log-1...&data=3-22

I logged because I got these codes when I did a pulls right after i added e85 in car and automatically did pulls ... cars runs and feels very fine

DME active codes -
29CC - DME: Combustion misfires, several cylinders.
29CD - DME: Combustion misfires, cylinder 1.
29CE - DME: Combustion misfires, cylinder 2.
2A97 - DME: Crankshaft sensor, gap fault.
2F8F - DME: Accelerator pedal module and brake pedal, plausibility.
3100 - DME: Boost-pressure control, deactivation.

- DME shadow (inactive) codes -
29F4 - DME: Catalytic-converter conversion.
29F5 - DME: Catalytic-converter conversion 2.
2AAF - DME: Fuel pump, plausibility

you have to post a log

did it climb that much during a pull or is it when you were sitting or driving in traffic ??
