Any help would be greatly appreciated! Thanks!

Initial spool seems a bit laggy. What spring do you have in the tial and have you performed the brass nipple mod on the manifold?

It has the -11 tial spring in it and I did the 1/4 tap in the manifold for vacuum.

Barometric pressure is 14.0 - so you are very close to 1200 feet altitude. That will mean you can get some benefits from a custom tune for both fuel scalers and WGdc controls. They could take some of the taper out of the OTS map and give you take more advantage of the Ethanol octane.

You dont indicate if its a DCT or manual (and the log does not show a shift), but a custom tune would be far and above over anything the OTS map will be at this level for DCT and DTC synergy. IN other words, you cant imagine the amount of DME intervention that will take place on the OTS map during a shift when you talk loads this far above what the OEM traction control expects.

You also get a 30degree IAT increase in about 8 seconds so some fuel needs to be added to keep that down.

Doesn't look bad to me at all. Those timing corrections are a feature of my car. Can't seem to get rid of them no matter what fuel i run.

I dont see the gear logged. It makes it hard to tell what the road load is. I guess this is 2nd thru 4th?

You will always get a few cyl retards (as it should be) right after the shift. Its when loads are the highest; if you dont get a few then the tune not close enough. As long as they back down soon after its ok.

Cyl 1 and 5 do look pretty noisy though. They might be getting a little oil in there.
You might consider a colder heat range plug.

[Ballistic]

Thanks for the feedback!

It's a 3,4,5 gear run. I already have gapped 5992 platinum plug's and fresh coils. Both didn't really help much. I don't really know what else to do to get rid of the timing pulls.

Well, that probably explains part of it. You get a 30 degree (and that's Celsius, and thats at least 46-47F) increase in IATs. That combined with the weight of the wagon is probably a little more than that map can do without some work. A custom tune could add some fuel and bring the IATs down and maybe keep timing pulls down some.

I'm getting roughness on idle, small shakes that i can feel on seat.
No shadow codes or active codes at all. Intake valves walnut blasted last week.

I took some logs hoping someone could take a look and see if theres something wierd
going on, that could point me to right direction.

Anyone recommend what to look at as far as data logging with MHD? How hard should I get on it and how fast should I be going to get a good datalog? I want to ensure the car is running right with out blowing anything up? Your feedback is appreciated.

[The_E92_Fan]

Ok im really going to need some help here. My car is always acting strange in one way or another. I cant get a decent pull in without something going wrong. Today i took 4 logs in a row to see the differences.
They are listed in order with time.

A short history- installed MHD v8 stage 2+ earlier this year and with it all new NGK plugs and delphi coils. Its been less than 10000 miles since the install.

During every pull for the past month, ive gotten throttle cut around 3500 rpm resulting in a few misfires. Last month i did a little work in the engine bay and started it up to the throttle not working. I fixed it by resetting the adaptations. A few days ago, while driving i got the half engine light, i read the codes and again, throttle. Reset and good to go. That same day, i start the car to head home and the throttle isn't working. Again, reset and good to go. Luckily, the throttle hasn't given me grief since then. The throttle issue would give the harsh, jumping idle.

Another issue is during logs, sometimes the throttle value will shoot to 80%, other times it won't, instead it will slowly climb. Same with the accelerator pedal position - as you'll see if you look at my logs - until i logged consecutively today, ive never seen it actually really 99%. Often it will look like the first log values, barely climbing throughout WOT. I swear in mashing the pedal like i should.

Another issue im seeing is the very low hpfp values during logs - dipping in the 500-600 range sometimes, yet never a misfire at cold start or idle.

During the first log, near the end of the pull i got many codes and at least 2 cylinders completely shut off. I pulled over to read the codes and saw cylinders 1 and 2 misfire, plus different throttle codes, as well as i think and far code. the weird thing is, i cleared the codes and everything instantly went back to normal. in fact i took the next 3 logs right after and I never shut off the car in between runs. if necessary i can go get them and list the codes here.

Im very concerned about the health of my car. I am also very confused as to why i cant get consistency in my pulls as far as throttle, accl pedal, and hpfp values. If i need to log again and take specific values, i can, no problem. I know a decent bit about these cars, but something is causing this inconsistency.

Any day at the 1/4 mile i can get consistent 12.2-12.6, but engine parameters are a different story.

I can guess that my issues are from: hpfp and throttle are on their way out, crappy coils already going bad, spark plug gap prob needs to be lowered from .02" to .018", and the v8 tune may be a bit too aggressive. These are educated guesses. Please dont say "well there ya go, replace everything and youre good"

If anyone has time to look at these, please do and shoot me your ideas. Id love to talk.

You got throttle set for linear or progressive? Part of that can be how the logging starts. If its auto it might not get the data initially. Not really a problem bc the best thing to do when reviewing a log is just zoom into the part that its 99p throttle - then you know you should be at max boost ( or close) and close to load targets.

Like this - https://datazap.me/u/335iv8bait/log-...-28&zoom=21-68

Well, first thing I see is some consistent deltas between boost target and mean. You are almost 2 psi down in the 4800 range. So these codes are they only misfires or are they also 30ff boost below target? How old is this n54 (as in miles). ? Does it have wastegate rattle at start? WGdcs are heading up at high rpm so its trying to meet target but not getting there.

I would start with WG vacuum hoses and then boost sels if they have not been done. Yes, pump pressures tend to fall off but thats above 6000. You got issues below that where it should be close to load target.

[The_E92_Fan]

pretty sure its progressive, as i have not changed it. im doing manual logging. Ive noticed for a few months that the decel rattle is getting more noticeable, but never on startup. Before i installed inlets, it was easy to grab the actuator rod and wiggle them. No 30ff codes, ever. This car is a 2010 with 128000 miles on the chassis, new engine with old stuff at 71000. Pretty sure it got new turbos around that time too. I still have no smoking with all cats deleted.

Vacuum canisters removed. i can check lines, but ive checked before recently and they didn't seem worn or cracked, but i can check again. I have adjusted the rear actuator rod, also done the washer install. Its possible i lost one and the actuator now has play. again, inlets make it hard to see. just checking is a few hour job and will require downpipes and engine to be lowered.

Would low boost cause throttle codes at startup and normal driving as well as cylinder shutoff at 5000 rpm? i dont believe so. Low boost is possible, but i believe there must be something else going on. also, i think im getting overboosting, causing throttle closure and causing misfires at that 3500 rpm range. i can guarantee that i notice no misfires when i have no throttle closures.

No but the irratic startup condition can be triggered by all kinds of things, not necessarily hardware or any fault related.

Throttle closures on V8 maps when over boost (most common) or load target is basically more of a 'feature' than on any OTS maps prior.

See if same thing happens on v7 map.

[The_E92_Fan]

ive thought about going back to v7. i think ill do that first thing and take a log on the way to work. i pulled the codes as well:
29CC multiple misfires
29CD misfire 1
29CF misfire 3
2CF7 throttle valve potentiometer 2, air mass
2CFB throttle adaptation value
2D09 THROTTLE.

the other day i was driving and "2CF7 throttle valve potentiometer 2, air mass" was the only code thrown my way.

If you cannot find the answer to your technical problem/question via the search, please start your own topic. Your car obviously has a fauly part (not tune related)

Ok then. Here ya go.

https://datazap.me/u/335iv8bait/log-...og=0&data=3-21

I swapped back to v7.1 this morning and took it for a spin. It felt smooth. So smooth i kept going into 4th. Ignore anything after the end of the 3-4 pull - i forgot to stop the log. The v7 maps are only asking for 17 pounds, the v8 maps ask for more. My rail pressure held up, my throttle and accl pedal values made sense, my boost was near target, less timing corrections. Its a much better map for my car. Others were right, v8 is too aggressive for those without fuel and ignition upgrades.

[Ballistic]

Doesn't look too shabby. Timing could be a little cleaner but it's within tolerences.
LPFP is on it's way out though. This probably also causes the HPFP to close in on it's threshold. Maybe the V8 map pushes it over the edge.

Upgrade/replace the LPFP and reset fuel and throttle adaptations.
Replacing plugs, coils, and eventually injectors might clean up the timing.

I recently bought an 09 335 xdrive 6mt. I've installed MHD, put a stage 1 map on the car and did a log, immediately saw -6 being pulled so I switched back to stage 0 and have been doing some logs. I still have -1 to -3 being pulled on all cylinders, AFR in boost is low 14's - mid 13's. I've been tuning cars since 2005 but I'm new to this platform. My other car is a big single 95 M3 on MS3PRO.

I was wondering if someone can check out my logs and look for an anomaly?

A few notes

The car has 106k, operates smoothly no issues with drivability.
The car has had regular maintenance done
I believe the low pump, high pump and injectors are original
I have not changed the plugs or coil packs
No codes
Reset all adaptions after flash

[Ballistic]

Pumps look good. Timing retractions are a designed feature and are not necessarily bad.

If it's on 106k original parts; replace the plugs,coils and injectors.
Then flash stage 1 & reset adaptations again. Do a 3rd gear pull to at least 6500rpm

[335e92tx]

And you can't run a log right after flash. Even for an S1 map it will need some driving and adapt time. Put at least half a tank of time on it. . make a few 20-100 runs.. then log.
