Any feedback on potential existing issues (LPFP, boost leaks, crappy gas...) would be greatly appreciated!
Was about 58 degrees outside at 200' elevation.

Info:

• 2010 E92 335Ci with auto transmission. 104K miles and original turbos
• VRSF 7" intercooler
• VRSF charge pipe and HKS BOV
• The following was done at about 5k miles ago
• Replaced all injectors with index 12
• Walnut blasted
• NGK plugs ILZKBR7B8DG (#95770)

I don't see any major issues other than the fact the stock mapping is not very good. Get the car flashed ASAP and enjoy your car.

Did WOT pulls a few days ago no problems, today though, misfires every time. First cylinger 2,and 6; then 1,3,5, and back to 2,6

Needless to say will check coils/plugs again (BL coils ordered 2 weeks ago, but not here yet, so the timing sucks that way)

I see HPFP dip when I go WOT, before it recovers. Car has 157K now, HPFP was first done at 60K under a recall

Here are the logs I could take (3 selectable)

Cold weather is likely cause of things, but it's not just misfires. All requests are dropping and hitting torque limiter 1 in 3rd on 2 of 3 logs and some major disparity between measured and calculated boost. Measured boost WOT looks like it's pegging out the TMAP sensor in spots, but part-throttle is worse. Looks like MAP is reading full vacuum, but TMAP is still reading boost. If you have rattle fix set (>50% DC @ 0% accelerator), I'd turn it off for now and let the WGs open up at low/no load.

Get in touch with your tuner and send the logs. Stop going WOT until it warms up significantly or the tune is adjusted in the cold weather.

Stfts are quite high mostly due to ethanol. Scalars need to be fixed or maybe can try a fuel adap, if its still there in mhd.
Lol must be warm there, we have been in the single digit past week.

Talking about the fuel scalars, I actually got a 2e90 Fuel Mixture code, filled with only 91 and I still get the error. Readapted the Lamda, mass air, fuel, throttle to see if it fixes the issue. Forgot to log to see if it's my fuel pump. If it is I'll be too lazy to remove all the mods to CPO warranty a fuel pump sadly.... time for stage 2 bucketless

In 4th (and also 3rd in the second log) you are running lean (14) at high boost and your stfts are 0 during that time. Could be causing 2e90...but this needs to be fixed.

I see, what do you think could be the issues? Highly doubt it's o2 sensors since they have less than 2k miles on them. I would assume possible leak in intake track. One thing I noticed is that I'm not exactly hitting target boost but about 1 psi off but I'm unsure if that is normal or not.

Also note is that this is the first time I've seen this running the MHD v8 maps. Never saw it on v7. If it does come back I'll flash back the v7 and see if the error comes back.

That’s pretty normal. I’m off by like 4-5 psi at redline due to my altitude haha

A guess is that the stfts got maxed out and then gave up?
Cant be leaks and stuff since leaning out is the problem

I was logging earlier but can't upload them till later tonight. One thing I've noticed is my ltft bank 1 is on avg 3% higher at 15-17% vs bank 2 at 11-14% while cruising. I haven't gotten a SES or 2e90 code yet but I also flashed the 91 oct map and not 91 acn.

Hopefully it's just a dumb issue and not o2 related because I just got them warrantied second week of December and too lazy to get under and do them myself even tho I just did downpipes lol

Heres about a 15 ish second log on me cruising on the freeway.

Hi guys is it normal for timing correction to occur during partial throttle.? I was on the freeway when id notice it fluctuate between -1 to -7 i noticed its load dependant.
I have 98 e92 stg 3 xhp dci and stage 1 mhd flash 98oct. No corrections at WOT. Any help will be appreciated.

Check the O2 sensors in the DPs and make sure the grey loom is in the rear DP and black in the front DP. Rear O2s have specific harnesses also and might also be reversed.

STFTs peg at 34%. Yours are high, as are your LTFTs, might be from the E85 or O2s. STFTs giving up is usually a sign of cat protection mode, but doesn't seem like it's running nearly rich enough to trigger that and running too lean to be on the cat protect AFR table. Check O2 placements first. If pre-cats are in the correct pipes, maybe try swapping the connectors on the rears and see if anything improves.

Absolutely. Do a search for N54 cruise timing corrections. 45-60 load (even higher uphill) 1750-2500rpm part throttle can be rampant with corrections. A lot of us have tried a lot of things: E85, VANOS (EGR), AFRs, etc. adjustments don't do anything for them. The only thing that put a dent in them for me was to just reduce the timing targets there. I'm in a hilly area and would routinely see up to 9° pulled on most/all cylinders at highway speed on inclines. It's low load part-throttle, so the corrections are more annoying to look at than anything. The idea is probably just to ask for a lot for economy/emissions in cruise area and let the DME remove whatever it can't use...

I should be complete gone of e85 at this point and filled up a full tank of california 91. Ill do another cruising log tomorrow to see how it goes.
Be pretty weird if they're swapped, im almost certain they are matched up correctly considering all the horror stories ive read.
Also for the harness on top of the engine, Black goes to the front and grey goes to the rear correct?

[RSL]

I was referring to the WOT logs, not the short cruise. The 0% trims on the cruise log is just pedal lift and AFR looks normal for cruise, but the LTFTs are way high and going up. That's definitely not normal. Also, do you have WG rattle set?

As for O2s, I always like to start with the easiest/most common things first. If they're correct, will at least rule it out...

Nope, I don't have WG rattle set. Only thing is sport cooling and linear throttle mapping which i did after this log.

[RSL]

Maybe that's what I was seeing in the cruise log. WGDC is 55-60% in places on very light throttle. Real boost is also slightly positive while calculated is substantially in vacuum.

Hmm one thing to note is I wired a switch to the exhaust valve solenoid. So i can turn it off and on regardless of what the ecu sends to the exhaust valve solenoid. I'll remove the switch and use it at normal operation and see if that will fix the issue. Tho I don't really see how this would affect the operation since it's equivalent to people removing/disconnect the solenoid instead of the golf tee mod.

At light throttle what should the wgdc ideally be at?

Wgdc in the 50s at light throttle is ok. You can see in my 5th gear log below early on. as mentioned your ltfts are way too high at part load. Boost mean is always zero or above, throttle takes care of the boost.

I see, well here is another log(pull) that i did.
I remove timing corrections to focus more on the fueling issue i have right now. Its also an octane higher to try out and there will definitely be timing corrections in this one.
I also noticed in this log that i go lean on high boost after changing from 3rd to 4th gear. Is this normal, I would think not.
The STFT also seem much more tame than when i had e85 in the fuel.

+1 I hardly ever log at cruise anymore, but did tonight on the way home. My WGDC stays mostly 35-50% on hybrids with stock base and torque request. My boost mean is also slightly positive with calculated in vacuum.

STFTs aren't tame for pump gas. In fact, bank 1 looks just as high as it was on the previous WOT log (with E85?), bank 2 dropped a bit on this one.

Yes, you're lean after the shift, that's when it stops trimming. IIRC, it's like that in all the logs, maybe a bit in 3rd on one of them.

Check the sensors. Primaries are probably be OK (would probably throw codes immediately and idle like crap if they were swapped), but rears could easily be plugged in backwards. No "DP fix" is installed, correct?

I see, and yes ive noticed it has stopped trimming in all logs, so i started to assume that was normal.
Correct no downpipe fix is installed. Guess ill pop under the car sunday and check if the secondaries sensors are correctly placed.

Heres also a log of me running the v7.1 maps.
The trims in the v7 logs seem better than the v8 logs but im not sure.

Pretty good. Short term trims are a little high. Your not getting much retards but thats bc your in third. If you can get a little post shift in there that would help. That is where everything will likely show. You are close to the load target so it will likely go a little over and the DME will intervene a bit.. but you can see how bad.

Thank you for the reply. I will try and run another log today and see how it looks.
