Maybe I should flash MHD Stock 0 first to see how the car responds before actuator adjustment.

Also I was wondering if "adaptations" may have something to do with the behavior?
No adaptations will impact boost, might smooth out the BCS over time. How many miles are on the car now? Could be any number of things still, including the turbos/WGs, but I'd definitely start by getting a known rom in there.

I have 120k on it. Mostly highway. I've never really abused the car by any means.

Hope you guys dont mind me posting here, I have an N54 but its in a Z4

I've got catless downpipes, charge pipe, SSQV, and stepped VRSF intercooler. I've recently swapped all injectors to index 12, walnut blasted and fitted the NGK 5992 gapped to 0.022.

I'm in the UK and its quite easy to get 99ron over here so flashed the 98 ron Stage 2+

here's my log:

https://datazap.me/u/nick9one1/log-1...14-21-24-25-29

everything look ok?

The boost is consistently 1psi under target, is this normal?

Man what is up w this log? Even the load requested is lower than stock. Car must be slow as dog. Timing corrections higher than anything, altho all cylinders seem in sync. Bank 1 seems a mess (lamda and stft)
What is going on?
I took off Mhd because i had to do a recall and i kept my n20 sensor which happened to go bad. How was my hpfp looking in my log ? While cruising on highway car lost power and i had to pull over, when trying to restart it would crank but not start and fuel pump pops up on idrive. I would have to wait at least 10 minutes before car would start up again. Took my car to bmw and they said my hpfp and injectors are both good.

Yea i listened w a mechanics stethoscope to adjust it to close at 5.9 HG.

I don’t believe it was even closing! So i turned it about 4-5 times. The car feels way different now.

Also i listened to my front turbo as well and it seems to be in much better condition. Meaning it is closing very close to 5.9 HG a barely seems to have any rattle when listening.

So hopefully I’m in good shape!

Can someone please look at my log. Been getting lean codes at idle. Checked all vacuum lines...no leak. Also noticed my throttle position dipped but acceleration was still 99%. Is that normal?

Exclamation Leaking injectors?

Hello,

Do you guys think I have leaking injectors in both banks? Bank 1 afr rises lazily after letting off gas and bank 2 afr shows an irregular peak which differs too much from bank 1 when shifting from 3rd to 4th.

https://datazap.me/u/n54dct/pull-3rd...ata=3-16-17-23

I have rough and stuttering idle to the point the engine almost stalls when cold starting. I don't have codes though. Car is 2009 and driven 155.000 km/96.000 miles, injectors are index 7. Seems clear to me that the injectors are leaking, but the thing that wonders me is that I have taken multiple logs and this is the only log that shows these signs. Thanks.

Can someone please enterpret these logs for me (they are metric)

stage 2+ 98RON tune
https://datazap.me/u/au-bmw335i/log-...og=0&data=3-20

Stage 2 95RON tune
https://datazap.me/u/au-bmw335i/log-...og=2&data=3-20

Details are 08 e90 335 with 5" FMIC and BMS downpipes. I only just installed MHD and am not sure what I should be looking at most (timing correct? WGDC? AFR?). To me they both look OK.

I logged both tunes as I am not sure which I will use given mods and the fact its a daily.

TIA.

You are far away from boost target, so you must check for boost leaks and/or vacuum problems...

you are overboosting which is why the throttle is closing to control the boost

log looks ok otherwise. in 4th gear all goes to hell due to iats going up. get a bigger intercooler

Thanks a bunch fam.

Also, the only consistent code I get is Bank 1 and 2 lean. Can this be the reason Im not targeting 18 pounds boost? Which sensors need to be replaced...before or after?

First data log, car doesn't feel like it's pulling as before.

This is my first data log so I might not of done it right.
I was running the car on shell v power, stage one with no mods, took my car to be walnut blasted, vacuum lines replaced, boost solenoids replaced, wastegate rattle fixed and he said he could gut my downpipes for £30 whilst they was off so I can run stage two so I thought why not until I get some down pipes, the car pulled great after having the work done and running stage two, felt like a different car, I took it for a spin a few days ago and it felt like the clutch was slipping and it it feels like it isn't boosting half as much as before, just done a couple of logs but didn't have a chance to do anymore, don't suppose anyone could help me out to figure out the problem, thanks!
