Haven't seen a thread for mhd logs so thought I'd start one for everyone who needs help. Starting with me lol

Not too sure what the cause is but it feels like my pulls aren't as hard as they should be. If you can help or give some friendly advice please do. Boost leak? No codes btw

Looks like you lifted off the gas? Pedal is not at 100% across the entire pull...

You need to take logs in "TIMYOYO" mode which means you hold traction control button for 5 seconds to turn off all nannies.

Here’s my 91 basemap log (PS2 car) from Wedge

Going to start at E30 next and see how far she can go

[Stage5Lurker]

Logs are ots maps from stage 2 93 octane. the first one has no adjustments vs second log having been adjusted by Justin himself. I got a code for Super knock in cylinder one.

Could someone look at these 2 logs? My car has seemed a little laggy lately and I'm not sure why. I recently cleaned my map and maf sensor which helped a bit. I have MHD stage 1, arm charge pipe, and BMS intake.

These members are going to soon make the jump slowly from this thread to rod bearing thread with these logs lol

His tune causes super knock. Dont worry bud thats just means ur car really loves it..make more boost.

Who's tune?

[Nick_F]

I ran a better log at lunch. I cleaned map sensor and it seemed to make my issues go away. Could someone look at this and let me know if anything is of concern?

Everything looks fine. IAT's increase about 20 degrees during the pull so if anything I would recommend upgrading the FMIC.

Stage lurker.. he has cylinders correcting up to 8 degrees and super knock codes. Those are like micro heart attacks for the engine.

But its a BMW it will handle everything .

Still new to tuning but correct me if I'm wrong. Those two logs by Stage Lurker aren't really comparable.

In the first log you can see he does a 3rd, 4th and 5th held all at WOT and the most serious timing corrections occur in 5th gear.

Second log is really only in 2nd and 3rd, so no idea if this second tune is safe.

That seem about right?

5 th gear corrections are there due to more load on the engine and low rpm so we cant say much from two logs BUT super knock codes are bad. Those are not common even on tuned engines. U have to reconsider everything when u see those codes. Regardless of how nice the tune looks from a few logs.

Alright thanks for the insight! I do have a fmic sitting in my living room but these Wisconsin temps are not fun at the moment haha

[Nick_F]

So I got the fmic and downpipe installed running 93 and it seems to pull fine but the graph makes me nervous with the timing corrections and boost spike.

https://datazap.me/u/fnick123/stage-2?log=0&data=3-4-14

Also, when I use the 91 octane map I dont have any timing corrections

tons of corrections and ur rail pressure is also oscillating

bbnks2 another log that looks like that over 3000 PSI

[Nick_F]

That could be the hesitation and roughness I feel under acceleration. I wonder if my hpfp is starting to go...

[BB 335i]

I'm pretty new to the BMW world. I recently I bought a 2011 335i Sedan. I recently put Intake filter, upgraded CP, evo 2 FMIC, and VRSF catted DP all in. Before reading on, I wanna say during the install of the FMIC the TIC plastic tube snapped right at the neck/mouth, making it a perfect break.was sealed with some plastic sealer glue for high heat that turns plastic as it dries, cant think of the name of it, but extremely hard after drying. I already orderd an upgraded TIC when it broke, but is not installed yet. The car seemed to be puling consistent, and throwing no codes at the time on stage 1 and 1+ so I thought for some miracle that sealant worked for now. Got HFDP installed. at this point and I have flashed stage 2+, and after 2-3 days after driving CEL came on, with 2 codes, one being the 3106 - Cat eff. low. The 2nd code is 2774 Air mass Plausibility-Air mass too high. Cleared them to see if they would come back, I tried switching through maps, and came back on every one except stg 0. Long story short, I unchecked my HF Cat box due to that seeming to work to get rid of the light on the stage 2+ and it seemed so far to keep the light off. I am still showing the Air mass one come back and showing in the monitor, but it isn't showing a CEL.I have not changed the new TIC yet. that is an obvious and easily potential reason to where I think boost might be leaking. Im going out today to check all other areas around CP, and FMIC, couplers and such. odd part is the code didn't come on until after the HF DP went on. but I suppose the leak could have been then or after too.
I was able to get 2 logs couple nights ago. But if you could confirm I may or may not have a boost leak. Basicly I see me only hitting a peak of 11.7, 11.5 and a lot of 10.0 peaks, and tapering down to 6,7,8,and 9 psi in 3, and about 8-9 peak with 3-4 taper in 2nd gear. I can get better logs but wanted you to take a look before I am flooring its repeatedly. If I have a boost leak I am really hoping it is the TIC, which is getting changed soon already.
So if you could give any feedback on anything you see in the log, and if not a boost leak then why im peaking way under peak and taper goals. I waited to change my plugs before the tune because they were only in the car for 5k or 6k miles. Car has 38k total miles now, so I wanted to do the coils next time the spark plugs get done and do them at the same time.
The basic stuff I can figure out, but most of it, I have no idea if its looks good or has major issues. any help would be appreciated.

I emailed Justin as well already this morning, but he is a busy guy and would like to know if maybe here see anything or not

Looks like a pretty bad boost leak.

thats what i would have thought but looks like more people have that issue, seems to be maybe tune related. Because ur pressure goes to above 3000 PSI. Post on main MHD thread

[BB 335i]

I was looking at that on mine afterreading some stuff earlier. on the 2 logs i have my rail psi hits 3k on one, 2.9k on other, and floats 2.2-2.5k while foots in it. Would my almost definite big boost leak casue it to work harder and run higher psi for any reason?

wont get to it today, but hope to have the TIC on which has a high chance of being the problem. just hope there are no others.

nothing else looked crazy out of whack? I mean the car still runs solid, but "low boost" setting which I know is affecting some things some.

Thanks for the look

Yea, I'm working with someone at MHD now. I think it might be the tune because at the 91 octane tune I dont have the hesitation or uneven line in the graph.

[Jwallace410]

2011 BMW e93 N55 w/ MHD stg 1 & 1.5 logs
Just upgraded to 5" VRSF IC and Lower CP. All clamps are tight. Also, Stock LPFP has been Replaced in past 6 months

First log (stg 1) shows rapid fluctuations in Rail Pressure at beginning of full throttle before smoothing out. Also shows alot of timing corrections at beginning of the run. https://datazap.me/u/jwallace410/new...-33&mark=40-17


Second Log (stg 1.5) shows same rail pressure except being WAAAY off boost target. https://datazap.me/u/jwallace410/fir...og=1&data=3-15

Third Log shows Corrections on cyl 5 & 6, as well as only being able to reach 8-9 lbs of boost. https://datazap.me/u/jwallace410/fir...15-20-32-33-34

Every one of my logs, regardless of map, shows the same rail pressure fluctiations at tip-in and a small spike of boost, then lowering back down to stock-like psi. The car feels a bit sluggish when logging as well. I feel like it should be running a bit better than this.

recently, new plugs were done with a gap of .28 (Bosch Stock Plugs) Im at a bit of a loss as to why I cannot reach boost higher than stock, regardless of map, and why it feels so sluggish at times. Im thinking the HPFP will need replaced soon.. Any advice would be greatly appreciated.
