Any comments? '09 335xi 6MT

My stock turbos are rattling and on the list for replacement but I still need to save some $$

Mods:
MHD Stage 2,+ 93 octane
Helix FMIC
CP-E catless DPs
ER CP w/ Tial BOV
ER oil cooler
VTT inlets
Mishimoto radiator

stock turbos and fueling

I also realize the logs aren't ideal... I had an opportunity with some clear space ahead and decided to see what I could capture.

Anybody have any feedback?

Thanks in advance...

Let me know what you think! Thanks in advance.

Yeah, what he said. Corrections arn't bad but you're really at load targets big time - thats whats causing throttle closures. So, you got one heatrange cooler plugs in there? If so, go with a custom tune, they can prob move load targets up a bit and play with some predictive stuff that will help on 93octane, but it will need more to give you much more boost and advance. You really got some limits on octane it looks like.. it should be able to get closer to 16+ psi and 6 degrees before retards are a REAL prob.

Try to get a log with the 3rd to 4th shift. If cyl pressures are at max thats when retards will peak.

Looks pretty good - but the fact that you got a retard on 2 cyls mid pull is not ideal. Try to get a shift in there and that will tell if the cyl pressures are too much at max load - from there you will know if some fueling might help or what.
Looks pretty good otherwise. Get ready to replace your LP pump.. its below 50 at max.

There's a pretty good delta between boost target and mean at 5000+. And WGdc,s are getting up there. It prob wont make a lot more boost than the current target.

I'm running ngk 5992 plugs, but they are probably due for changing soon. Do you think that would help? I was really hoping to stick with OTS maps. Any other things I can do to prevent overboosting?

Dont think of it as overboost, for the v8 maps is more of a 'feature' to keep spool up. Normally the targets would be a little further apart and you would not be quite as close to it. You can throw some ethanol in but that wont move the load targets up, it will only let you see if the octane is preventing you from maximizing this map - but thats not gonna give you much.

Guys, safe to say I should get a boost leak test done? I just did my plugs and the car still won't hit target PSI. I dont have my intercooler installed yet, but I did this 3rd-4th pull tonight at about 7 Celsius (44 Fahrenheit) out. Am I missing something?

Hey, thanks for the feedback!

It's good to know that I can tell my wife that an LPFP upgrade is a maintenance expense

As for the snails... just gotta keep saving. I only really want to get to 550-600awhp, so nothing too crazy. I would rather autocross than drag...

Appreciate the info. I threw in some e85 and flashed to the e30 map but results look pretty similar.

I pulled a log of this condition and am hoping someone can provide some insight as to what's going on. There's also a log of a pull in the same link (change logs.) Thank you!

No replies, but thought maybe the learned behavior may have been thrown off with the new downpipes. I reset adaptations and it is smooth as ever. Feed back on log welcome (stg2, 93oct)

Yep, best first step. If that doesnt do it things get complicated.

Hi guys, im a new member but a long time reader on this forum. I hope you guys can help me understand my data log. I’ve installed a DP and CP 3 days ago and tuned with mhd stage 2. I tried to do a quick pull data logging for the first time and wasn’t even sure if i did it right so please bare with me. I think i didn’t even make past 5500 rpm as the road i was on wasn’t sufficient to do so. I pulled the log and i noticed that my car has made timing corrections on all cylinders and they are all over, i’ve tried reading about it and it seems no good.
So now i need some help with this.

Here’s my car’s background history:
2011 335i xdrive 6spd with 140k km
MHD stage 2 91oct, vrsf dp and cp, muffler delete.
Cylinder head, vanos solenoids, vcg, hg, ofhg has been changed through warranty roughly about 25k km ago.
MAF and oem sparkplugs, waterpump, t-stat has been changed 20k km ago.
I believe the coils hasnt been changed ever since and now on my next to do list.
I don’t race or abuse my car, quick 2nd to 3rd gear wot maybe once or twice a month.
I suspect i’m having the infamous pcv problem for n55 as i can hear chipmunks like sound intermittently when braking and coming to a stop.

Does having a bad coils can affect timing corrections?
Here is my log.

Hope you guys can help me. Thanks a lot!

But, you got bigger issues on the shift. DME is probably pulling power and closing throttle due to torque limits. And when it goes back to power you get retards. A custom tune could work those out.

Thank you! May be i was a little to sensitive on the target and actual boost thing.

The throttle closure is nothing more than secondary boost control due to the RPM drop and boost overshooting target. I'm working on fixing that with the next map release, but the forum tuners don't understand that boost target doesn't commend boost, it's a ceiling which I can control with BLM and load request. There are a few other factors, but I won't go into detail. Bottom line, depending on conditions you might not boost to target and that's OK. There is nothing that says you need to increase WGDC so that boost is riding target. Nice thing about keeping boost target lower than load request is that target only closes the throttle and doesn't cause a massive drop it WGDC so the car remains smooth and pulls through the throttle closure without you even feeling it.

BTW, the post shift corrections are common. More than likely your octane level is boarder line and the cylinder pressure post shift is high enough you're seeing a bit more noise that the knock sensors are picking up on.

I'll shoot you an email with the information I need. Then you can post up the new logs once we figure out your torque limit 4 issue.

Funny i just saw this reply right now Thank you for your detailled explanation and the support over E-Mail.

Yeah. I am on DCT.

After some email exchanges we figured that i have no issues during the shift nor any power loss or weird effects.

Wedge states that it might not be an issue of my Map but rather the DCT Software (8608092) forcing the tq limiter 4.

There is the opinion that IS DCT Software might help here.

I am not sure what to do now as i am very happy the way my car drives right now and the DCT is working flawless. No Slip or anything.

Is there a potential safety issue with that Torque Limiter?!

I have never done a log before, and am not 100% sure if I did it properly, or what items to choose to check over. Could someone please see attached log and provide feedback, it would be much appreciated. Thank you!!

Well,ideally you need to get a shift in there to see what the DME Does when load gets really close to target. You might get cyl retards or throttle closures.
I would Turn off the following log parameters


WGBase value
WGDC #2 (should be what #1 is)

And the log shows you about 60 percent accelerator pedal.. Are you flooring it? Try to get one that at least pulls to say 6300 rpm (3rd prefereably) and then let it shift into 4th and pull a little more.. And dont get in over your head with speed...

Since this is an S1 map you really wont be pushing it much. S2 is when things start happening quick and one event can affect another.

Thank you, I will remove those two things, and do a pull on the way home from work. I will repost log later !

What is the value I need to look at to see if I need the Tq bog delete option on or not?

log looks ok... your lpfp dips to 52psi at one point, make sure it doesnt go below 50psi...it wouldnt hurt to upgrade your low pressure fuel pump since it dips that low on pump gas only ...couple cylinders have some minor timing pulls, could be that your gas is not as good for your tune as it should be... a gallon or 2 of e85 should clear that up ( if you have access to it )

Any one able to put their finger on what's going on with my bank one afr off throttle?
bank 1's afr seems to not go full lean off throttle but instead bounces around as if fuel is still going through that bank. Now i fully disconnected bank 1's injectors from the fuel rail and connected some old index 1's just to blank them off so no fuel was going through bank 1 at all but same thing happened.

This also happened right after replacing the o2 as a preventive maintenance thing.

Below is a log showing bank 1 not settling at full lean off throttle compared to bank 2.

No problems with the lpfp but you should have invested that money in an upgrade intercooler, your IAT is rising very quick for a single gear pull. You realise you flashed a map that requires an upgrade intercooler. For regular mhd maps you dont even need a stage 2 lpfp, I can even run an E50 map with stock lpfp.
