Same for you, you need an upgraded ic, rtfm!

Stage 2 is supposed to have catless DPs too I believe...

[n0tm3]

chasing an occasional long crank/rough start problem, any second opinions? Also pretty sure a new IC is next on the list.

second log is warmed up more, taken the same day.

That map is too much for your car, high IAT rise and massive timing pulls... You need a better intercooler, better fuel or a lower map.

Agreed...may have an issue with an injector in bank 2 also...

gotcha, usually keep it stage 1 but wanted to see how + would hold up. IC is a givin, and timing just due to aggressive tune, even with new coils/plugs? 93oct is the best i can get around here also.

Waiting for my tank to run out so i can try some injector cleaner already. Rockin' with index 12 so new injectors are not happening

Your LPFP is plateaued around 50 psi for a large part of the run too...it may be on its way out...

Need Help!

Caught a misfire on log a little while ago, here,

https://datazap.me/u/fredcase/log-1545415835

then swapped plug cyl 4 plug to cyl 2, and coil to 3. Took it easy for a bit, and drove other car. Drove this one today and BAM! These 2 Logs, so, any wot=cel, misfire 2+4.
Could use some insight before I start throwing money at this.

2 Logs here. No timing corrections on 1, something fuel or vanos. Help please.

You are running very lean both banks but especially bank2. Careful!

Tune? Injectors? Fuel pumps? What should I Try?

may be injectors...what are the codes?

Plugs 10,000km, coils are long in the tooth.

When I first got the cyl 4 misfire (first log attached) I swapped the plug to 2, and coil to 3, misfire stayed in 4. Leading me to believe it's the Injector. I'd like to be more sure before I throw $1500 at it.

do a complete set of coils first bro. You will have to before long anyway.. when you lean on it more ;-)

Then do a set of injs.

New at reading logs, this is around my 6th 4th gear run. Do i have a leak? the wgdc seems high.. but i'm not enough of an expert. I know it's not an n54 but i saw some other n55 posts on this thread so was hoping someone could let me know if i need to look at something.

Hi was wondering if someone could look at my log. I am running MHD stage 2, on a 2009 335i. For mods I have DCI, Chargepipe + Tial BOV, and Catless Downpipes. I have noticed I havent been able to hit full boost ever since chargepipe install, but im only missing boost by one psi; is it that big of a deal?

Thank you

I think the boost signature looks strange...typically it’s smoother to target than that. I also thought the stage 2 boost was higher than that although I might be mistaken...

That could be do to me running a 8 lb spring? Not sure though
or just do to me not being good at running logs; I tried to a third gear pull, am I supposed to push fully to hit the button at the back of the pedal?

Yeah that log isn't very helpful, you did a kickdown from 3rd to 2nd on an auto trans I suspect. You need to manual select 3rd gear let the revs get to 2k rpm, smash the throttle and hold it until 4th gear around 6k rpm and report back. Small problems not hitting boost target can be vaccuum lines, boost solenoids, O-ring failures, clamps,...

I suspected it wasn’t the best log, I will repeat today or tomorrow. Thank you
