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. Quote:

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... Quote:

Fist time data logging
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. https://datazap.me/u/mackie/log-1544...-25-26&mark=63 Hope you guys can help me. Thanks a lot! |

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.

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 ) 2007 E92 335i / VRSF 5" FMIC / VRSF Charge Pipe / VRSF DCI / VRSF Downpipe / TurboSmart Plumb Back DV / XHP / E40 Custom Tune by Wedge / APEX ARC8 / Michelin PS4S / 11.95 @ 116 / Instagram.com/silent11n54 |

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. https://datazap.me/u/napsterau/fuel-...&zoom=987-1038 |

Can anyone check this log out and see if it looks ok. I was having some problems with misfires and fluctuating LPFP psi. I just switch to a EKPM3 and took a log. 2007 335i e92. FMIC, chargepipe, downpipes, stage 2 LPFP |
