I just received my NGK 97506s today, I'm planning to swap these in today with a 0.022" gap and re-log, hoping this smooths out the upper range. No codes currently, everything seems healthy but there could be a slight misfire I'm not noticing on the top end.

How are you seeing the knock? Maybe I'm missing something but I thought the "knock detected" value would change from 0 to report this?

Knock detected is 1 at 6527.

Ah, I assumed from your original post that "double click" meant "double tap", e.g., a mobile-only feature. I'll try double-clicking the graphs in the dashboard next time.

erratic WGDC in top end started for me with version 7.1 of OTS stage 2 tune, so i'm sort of glad to see it in others for more data points. it's not noticable while driving. i have not investigated yet, but could be due to tune's boost control, a small boost leak that happens at high pressure, a leaky diverter valve at high pressure (Halim's feedback).

FWIW i don't see it running MHD stage 2+ at similar boost levels, although i usually don't rev past 6500 or so because i find it unnecessary lol. Stock DV.

Just want to clarify since there are a lot of new members posting recently.

I looked at https://www.bootmod3.net/log?id=5eb1...729b60ed44cd27

Overboost early on, which seems typical of BM3 recently. You do have throttle closures.

You have the same wavy/unsteady boost and WGDC up top over 6300. Not sure why.

Your STFTs are quite high - up to 1.20 and even a little higher, so the DME is having to add 20% fuel... that seems excessive to me. Maybe a vacuum leak? Not sure.

THREE knock events during the pull. What octane fuel are you running? I would probably try a lower octane map.

Timing honestly looks horrible. Again could be an octane issue.

Your MAF readings are all over the place as well; not a smooth curve. Could also suggest a vacuum leak.

Given all that, i highly suggest emailing PTF. I can almost guarantee they will tell you to run a lower octane map.

Thanks for the feedback, I'm looking to learn and to understand whats normal or what I should be looking for.

I am running 7.1, interesting that there is someone else that has a wavy WGDC in high RPMS. I was initial concerned about a boost leak due to the high WGDC values, is that anything to worry about?

As far as the MAF, Ive had issues since installing the BMS intake on cold starts even before running bootmod3, where it will idle exremely for 15 seconds or so then jump up to 1000 RPM back down and smooth out. I wonder if that's screwing with the MAF?

I'm running top tier 93 here in North Texas which I've not heard of being a poor mix.

Will definitely email PTF to see what they say. Thanks for looking at the logs, its exremely valuable!

I would just compare your logs to others running the same tune with same DP setup (catted or catless). Usually if you have a leak boost control will also be off. WGDC can be high because these tunes are pushing the turbo pretty hard.

I am pretty sure the rough cold start is a known "issue" (side effect) of that intake; the different shape and whatnot can affect the MAF readings. Not the place for a intake discussion, but i would go back to stock if you want to confirm that is the issue. Plenty of other threads on intakes.

Please report back what PTF says.

In terms of log reading, i have posted this other places and will repost here. At a high level:

1. Check boost vs boost target. +/- 1 psi generally considered normal. Significantly below target might be an issue. Overboosting can also be an issue. Make sure you look at MAP, not pre-throttle boost only.

2. Check HPFP vs target. Dips in actual vs target ("crashing") indicates a fueling issue - i.e., too much boost, too much ethanol, etc. HPFP cant keep up with air demand.

3. Check throttle angle. If its not 100% when you are WOT figure out why. Make sure no unexpected throttle closures, or lack of closure when there should be (e.g., overboost).

4. Check timing/timing corrections and knock. Knock or lots of corrections (pulling timing) points to an octane issue (octane too low).

5. Check WGDC. If it is excessively high, you might have an issue (e.g., boost leak) that is causing your turbo to work harder than it needs to. Note differences with EWG vs PWG "normal" values.

Secondary checks:

6. Check AFR generally speaking and target. Check STFTs for corrections.

7. Check IATs (usually not an issue with IC, but can be helpful when trying to figure out other issues - e.g., very low IAT, high ethanol content could lead to HPFP crash with stock HPFP and a high boost tune or on the flip side, high IATs could lead to timing being pulled).

8. Look for any unusual behavior in any logged parameter (erratic readings from MAF or other parameters, curves that aren't smooth, etc).

If you really want to learn, just keep following threads of people looking at logs and see what they talk about and inspect the log for yourself.

Thanks again, that's a wealth of insight. I just ran log on the stock tune.

https://www.bootmod3.net/log?id=5eb1...0b43688000f525

I'm on mobile rn, but from looking on a tiny screen I see the throttle angle pulls back and also timing seems to be pulled also. I'll dig feeling when I'm back to my pc. I'm pulling off the intake later and will test with stock.

https://www.bootmod3.net/log?id=5ec3...90c610abc87714

shared this on another thread, Id love to get more input. my throttle angle starts closing around 6900 the same time the iat's are high so im guessing I might need an IC. Anything else that sticks out or might cause same.

[ChristosD]

hi if possible can any one check my log v7.1 stage 2 93 map with meth does it look like i have a boost leak?

What makes you think you have a boost leak?

two things

visually i can see oil around the bottom of my cp and there is absolutely nothing leaking im thinking possibly boost blow by?

secondly at top end im loosing well over 1,5psi? is that normal?

Yes your IAT'S are hitting 100 mid rpm, so yes you need to upgrade your IC.

You will certainly lose power once you pass 6500 on stock turbo, maybe even sooner since the stock turbo is out of its efficiency range past 5500rpms.

Are you hitting the rev limiter in this log? Shows you reach past 7000rpms which i would highly recommend you never do!

Yes to both.

Blow by will always collect in the charge pipe but if you had a leak it would show in your log.

Stock turbo runs out of gas past 6500rpms. Even with a upgraded HPFP or WMI, you will only be able to hold a bit more boost past 6500rpms

EDIT:

yes boost deviation of 1-1.5 is normal. Your throttle closure is your DME trying to keep you engine safe!

I am thinking about getting BM3 but I have not found much information from anyone running the stage 1 91 octane map. Does anyone here have any experience from it?
My 335i PWG currently has MPPK (ECU and airfilter box only), aftermarket charge pipe and upgraded no name IC.
I intend to run the basic stage 1 map for 91 octane. Will there be a noticable difference in performance and can I expect it to work flawlessly?

Yes, stage 1 is less common. Stage 1 will still be a step up over MPPK.

Can you expect it to work flawlessly.... you can read through the BM3 thread and determine that for yourself lol. It should work fine. Given that stage 1 wont really push you to the limit of your HPFP for example, i wouldn't expect some of the same concerns as say, stage 2 ethanol mix map. But there is never a guarantee everything will work flawlessly when you mod your car.

Not sure if this is the right place. If someone will be kind enough to look at these logs. I recently flashed OTS EWG Stage 1 93 Octane, added Wagner Comp I FMIC and FTP CP, had MPE and CTS Turbo intake already. The car has 49k miles, 2016 435ix 8AT. Overall it feels great with some not so smooth shifts, maybe need to flash transmission too? Not sure about this but there seems to be some sort of turbo lag or I just need to get used to the power delivery.

It gets scary around 6k rpm, should I be taking it up to 7k?

1st run, in 4th gear from 2.5k rpm to around 6-6.5k rpm:

Your logs actually look pretty solid for the most part. I would say that you need to make sure the pedal is buried at 100% for the entire pull.

Boost target vs actual, IATs, hpfp, stft, and wgdc all seem to be solid.

Your timing is all over the place and you're leaving some power on the table. How old are plugs/coils? Are they both stock? Could also be bad gas causing the timing issues.

I found that my logs look cleaner and seems to be healthier for the car when I shift at <6500. I try to shift 6000-6300 most of the time....no need to run it on out. Power falls off too much on the top end and of course the higher risk of something breaking.

I have the XHP stage 2 transmission flash and absolutely love it. Would recommend it to any and everyone.

Thank you ! Really appreciate it.

Yes I think my plugs and coils are all stock except one that was changed when I was having a misfire in one of the cylinders about a year ago. Should I replace both coils and plugs to be safe? I use the 93 octane gas from Costco, filled up at a Mobil station yesterday and will do a couple of pulls with pedal pushed all the way up to 6000-6300rpm and gather those logs.

Will look into xhp too, transmission/shifts do feel a bit jumpy but I think it's getting better, have only driven about 30 miles since the flash. xhp stage 2 is good for both bm3 stage 1 as well as stage 2?

I would echo everything here, the only issue in the logs is timing. Its quite bad honestly. A ton of timing being pulled, uneven timing between cylinders, etc. You're only running 1.5-5.6 degrees of timing up top, which is super low. Definitely huge power loss here.

I would try 2 more 4th gear logs on a new tank of gas and if timing is not cleaned up, put new OEM plugs in. Don't throw coils at it unless they are determined to be needed.

Also agree with shifting at <6500. I do log up to 6500 sometimes just to get data but during normal circumstances its unnecessary.

Also echo getting XHP. Its independent of BM3 tune and works on everything from stock car up to big turbo etc. You could try the BM3 free trans tune first if you wanted.

Just took a quick look through. They look OK. Cyl 3 has timing pulled throughout the 2nd log. If it continues to do that in future logs might want to pull the plug and check the gap. STFT are also a bit negative, not crazy so, but MAF signal is erratic at the same time. Are you on stock intake?

Thank you, already got gas at a different place, will log again later. What would ideal ignition timing look like? I also changed the burble setting to OTS, could that cause any issues?
Speaking of plugs, would it be better to just get the NGK plugs instead of OEM?
