MHD "take a look at my log" thread

Here's my first log e50 tune (base map).

currently fbo e85 with port injection. any ideas on why I run out of rail pressure?

How old is your HPFP?
Are you running upgraded LPFP?

Looks pretty good. Slight timing corrections on Cyl 5 so just keep an eye on that.

Wingnutts · 06-25-2019, 08:31 AM

I am not experiencing any problems that I notice with the exception that I wish certain numbers were higher. However as I progress with putting on the DCI and FMIC next week as well as my new NGK's (if they come in...), is there anything noticeable to anyone that would require my attention or I should keep an eye on?

MHD V.8 stage 1+, e30 map

Thanks for your help!

I'll start of by saying you desperately need an upgraded FMIC if you run that map. I'm no expert but I'm running the same map and IAT's used to climb like yours 30F on one 3rd gear pull. Otherwise it looks good to me. Take a look at mine after installing the VRSF 5" HD https://datazap.me/u/curt/new-fmic-0...data=3-6-15-22

yours with IAT's tracked https://datazap.me/u/grunt/log-15614...data=3-6-18-25

I was in the same boat a couple of months ago. I dont worry about that anymore. Interesting your boost runs a tad higher (approx 1psi throughout) than mine on the same map?? Maybe because its an IS ??
Here's a log before I did the FMIC and the boost was slightly higher Hmm slight boost loss but it feels stronger

I was a little preemptive in loading that map without the FMIC, but I was "bored and impatient..." waiting for my FMIC to arrive. My logic to my madness is that I only get on it once or twice a drive if even that. The wife and kids frown upon the spirited driving.

The VRSF 5" is what I ordered, so thanks for posting your file! As for my boost running higher, I am unsure. Once the MHD tune hit the dme, my "is" is the same as your "i" as far as tuning.

Thanks,
Jason

You are nowhere near boost target - simplest explanation is boost leak. Also serious timing corrections which may be unrelated to that. Do not flash higher performance map until you resolve this.

First log running MHD v8 Stage 1+ E30 Map. Can I get some opinions on my log, it would be greatly appreciated! To me, boost is off by a couple psi. Is that normal? Does anything else stand out? Thanks!

I'm new to all of this, but I've "read" numerous times that if you're within 1 to 1 1/2 lbs of your boost target, that is normal/acceptable.

Can anyone verify this as true? Or have I been reading bad information on the different sites?

That's the way I understand it too! Within 1psi of target but it should get to target during the pull.
Your logic on running the 1+ E30 map on stock IC is the same as mine was. I couldn't wait either but now that's its on its nice not thinking about IAT's anymore.

I believe I should be hitting target boost at the beginning of the pull, and then taper 1 to 2 psi after that.

Hey guys. Completely new to data logging but trying to help my dad out here with his 2010 535xi (N54). Hes running a MHD stage 1 tune on an otherwise stick car. He’s been having some fuel pressure problems and a couple times in the past month, the car will completely shut off while driving around town. He’s able to start it back up and it drives fine like nothing happened.

I had him do a 3rd gear pull and log the data. He forgot to shift to 4th so hopefully this gives enough info. I’m looking at the low pressure graph and know it’s supposed to fluctuate but the lull in the middle seems strange. LPFP failing?

https://datazap.me/u/ryansbmw/2010-5...og=0&data=3-20

Any other comments on this data? Seems like he might have a bit of a boost vacuum leak or solenoid problem.

Here’s the codes he pulled as well.
Active:
29DC- DME; Cylinder Injection Cutout
29F2- DME; Fuel High pressure System, Fuel pressure

Shadow:
2AAE- DMW; Fuel Pump
2FCA- Fuel High Pressure ( followed by a bunch of german)
2FDA- Fuel High Pressure ( followed by a bunch of german)
2FDB- Fuel High Pressure ( followed by a bunch of german)

HPFP failing? HPFP being pulled down by the LPFP?

It actually looks pretty clean.
That was a 2nd gear pull. Have him do another in 3rd. Those codes point to the HPFP but if you are above 1700 you should be fine.

Ugh..the man cant listen to simple directions haha.

Thanks for your input tho. My initial thought was hpfp but I havent read much about the entire car shutting off when that fails. Its always reduced power, long cranks, etc.

Looking at the LPF sensor, that area between 3800 and 6000rpm where the low pressure sensor drops and stops following the rpm curve isnt a concern?

Not really. It's only one log. You need a few to compare. If it dips like that often, then I would consider changing it.
What is strange is that the HPFP looks great in terms of pressure but you are throwing all those codes pointing to it. Keep digging and something will stand out.

I got port injection. Fixed the issue just trying to make the start up better with the start up roar it's currently ass

924er · 06-26-2019, 02:03 PM

I switched from v7 to v8 naps and noticed my cold start no longer revs high. I don't recall disabling it, anyone else notice that? I like my high revs on cold start lol

charmander · 06-26-2019, 11:45 PM

Thanks for the feedback so far guys.

Below is my log on stock settings. No sign of boost leak at stock boost levels, but it seems like timing is worse at stock than at stage 1. Could this be a hardware issue?

Switched to V5 e40 map today as I heard it is more aggressive then V8 E50.

I saw it has an option to desensitize knock.

Sounds sketchy for a few extra hp up top. Any thoughts?

There's a link in here that explains what "normal" looks like on data logs...

Low pressure fuel pump should rear 72psi at idol. The OP should use this gauge in MHD to verify. It should also move up as you rev the engine.

I'd replace the Low pressure fuel sensor before I replaced the LFFP. Especially, if it's original to the car and you are over 100,000 miles.
