Unfortunately, can't force more boost out of a already tiny turbo

If he wants more power, he has to swap the turbo. Even if he does max out the stock turbo, he can only make power to 5k rpm, and it will always drop off hard from there unfortunately, and you risk overspinning the turbo at that point, not very reliable power.

PS1 would be the best cost/power ratio, it's cheap, and if you want to upgrade to PS2 in the future, you just pay the difference.

Yup i know it has its limitations. Making it breathe a little easier wont hurt though, and might squeeze out a psi or two without overworking it (analogous to WGDC decrease at a given boost level).

The inlet BMW initially sized for the f30 N55 fit the pwg turbo. They didn't increase the size of the inlet when they switched to the ewg turbo. I'm sure an aftermarket inlet will help a pwg turbo flow a bit better, but not like it does for the ewg turbos.

Going to hold off on any more mods unless it's good wheels and suspension. Honestly, I should stop since I'm trying to buy my first condo....

I have never tried to pull my oil cap off while the engine is running so i am not 100% sure if this car builds vacuum in the crankcase under normal conditions.

so here are 3 new logs from today after reseting the adaptations and the logs are a whole lot shorter and only when it was doing

sorry i dont have a video to show how the car sounds but is like hicups/misfires/sputters

The main things that stand out are:

Your STFT is extremely high, like +25% in one of the logs, and generally high in all of them.

Your timing is all over the place and even goes negative... not good.

RPM and MAF are both really erratic. RPM i assume because of the misfires... are you running an intake? What's your full mod list? Did you change anything right before the problem started? Did it happen on the sudden or get progressively worse?

Have you tried flashing back to stock / stage 0 to see how the car runs?

Was the problem there before you did plugs and coils?

mod list is regular FBO catless downpipe intake fmic chargepipe .



ive always felt these little small hicups but it was very rare before and just little by little i started to feel them get worse and worse

for example now i feel like it is way worse

and only on part throttle when i do wot i honestly dont feel nothing ocasionaly i might get a small misfire but is very rare
danmm car runs better on wot lol

but i mean no danmm codes i reset the adaptations i think my next is going to see how my car feels with stock tune and see if it still does it

and i havent changed anything besides new plugs


do you think i need new coil packs maybe


pro tunning freaks are saying is a fuel problem maybe a bad injector or something

i just sent them these 3 logs here and waiting on a response from them

What stands out to me out of all those logs is his car was either misfiring or studdering so much, it looked like he wasn't even going WOT.

The logs are pretty unreadable until throttle angle stays at 100% throughout the entire RPM band. (2.5k to 6500rpm)

yeah i wasnt i dont need to go wot for the car to misfire etc.


when ever i do a wot pull i feel like it doesnt sputter at all or if it does is so slightly you cant even notice it and is so rare when it happens


it is a hot day today is about 86 plus

What type of plugs are you running? GAP? Last time they were swapped?

spark plugs are brand new maybe 100 miles ago



and i am running stock plugs thats what pro tuniing freaks told me to run

so thats what i ran with

Yeah saw he wasnt WOT. He said it works fine at WOT and the idea was to log the issue occuring.

Then try stage 1 and see what happens. It seems strange that it only happens at part throttle, and WOT works even on the stage 2 tune... so i wouldnt think it would be boost related. It's worth mentioning to PTF that stock tune does not have the issue.

Do a WOT pull, a partial throttle it doesn't matter as much, if your car misfires at partial throttle, it should at WOT as well. If something is wrong, we can see it on the logs.

Looks to me like an issue with the throttle mapping in the tune. The first log throttle angle and target boost are more inline with where the pedal actually was and that log looks the smoothest from an rpm standpoint.
The other two logs are a hot mess, accel pedal at like 50% but throttle angle 100% and boost target is as if your pedal was 100%! In that instance the dme might be getting conflicting information as to what load to target and is fighting itself hence the crazy erratic rpm... that must have felt like shit in the drivers seat wow.

Send those logs to PTF support and ask why the car is demanding max boost at half throttle and kicking and bucking like a bronco.

Yeah exactly driver seat feels like shit


The way you explained it is how I honestly feel the car

I can be 50 percent throttle
And the car feels like is already at max boost and is just going crazy trying to take off


Right now I tested out stock tune the car felt amazing nice and smooth no hiccups at all


and yeah I sent those 3 logs to pro tunning freaks to see what's there comments on those 3 logs but

Yeah it feels wack and sounds like shit lol
Basically sputtering all through the gear

Like if it was some type of ignition coil problem or idk

But I just don't get a Danmm check engine light or a code nothing

Hello all! I'm learning more and more about logging each day. I've re-run some logs with the proper data this time. I'm getting what feels like braking up around 5.5k rmp through 6.5k rpm. To me they look ok except for timing. Please correct me if I'm wrong but timing looks off in several of the logs near the mid/higher RPM range. More specifically, cylinder 3 and 4?

2014 335i Xdrive N55 EWG 56k mikes
Stage 1 bm3 93octane version 7.1
Stock Bosch plugs/coils with stock gap with less than 3k miles
VRSF chargepipe and 5inch hd front mount intercooler

Thank you guys for the help in advance, it's truly appreciated!

If he was in sport or sport+, that is completely normal throttle mapping and has nothing to do with the tune. Even stock tune does that. Look at attached images. in sport/sport+, the DME comands 100% throttle open at 41% pedal input. in comfort, it commants 100% at 70% pedal. That's just what makes the throttle feel so sensitive. (although of course sport/sport+ also change things like WGDC mapping, etc, but here im talking specifically to throttle mapping). There is never a 1:1 mapping of pedal input to commanded throttle position unless you run linear throttle mapping flash option in MHD or have it custom tuned.

The timing in the first three logs doesn't look great (the last one won't load). Might be worth trying the 91 octane map or different gas. I've found the boost characteristics on 7.1 stage 1 to be a bit odd - stage 2 seems more steady from the logs I've seen. My boost characteristics on stage 1 look exactly the same as yours (if that's any conciliation). I haven't had time to do more experimenting. Maybe others will have more input.

Well maybe throttle mapping was not the correct term. What I was trying to get at was that at 50% pedal the tune is demanding full boost and some parameter is off and doesn't like it hence the jerkiness and crazy rough rpm.

People are way to quick to start blaming hardware or swapping plugs or coils or blaming fuel quality. The fact is that in this case at part throttle on stock tune the car runs fine, part throttle on ots map car runs like shit. The reason is because something in the tune isn't working as it should and it can be rectified by PTF support, that's what they are there for.

Anyone want to take a look at my logs for fun? E30 Stage 2 map. Filled it with 15 miles left to empty. Added 5 gallons of pump gas and 2 gallons of e85. Thanks
