At this point I'm leaning more towards repairing the wastegate bushing if I can find a high quality bushing kit, or the DocRace V2 kit. Just keep throwing $$ at it I guess .

Yeah try WG repair kit if you can do it yourself, before throwing $$$$ at it with another turbo kit.

Its been a while since i last posted my last log , Since then ive done many updrades the last was last friday had new upgraded turbos 17ts 11 blades installed along with replacing all 02 sensors,inlets,outlets,boost solionds,new valve cover,new coils , step 2 colder plugs.

one thing i do notice is the spool sound is louder then when oem turbo is this expected?

Here is a log the tuner had asked me to check some boxes to send logs so if its not what you need to view my logs properly let me know which parimerts to select,
Current mods are FBO With Upgraded Turbos.
Alot of maintenice parts have been replaced.

Thank You !

Looks better than mine, I would probably just do a clean 3rd gear 3k-6k log ..easier to read and gives good picture without the higher gear risk of issues under load. What is the question ?

Any suggestions of which flapper kit ? So far seems like chinesium .. I'd like to find some high quality ones if possible. Also it seems TurboLabs has disconnected their phone# and recent reviews have been trending down ...

I'm not sure which to recommend to be honest, haven't done it myself.

New build on custom base tune. Trying to hammer out big issues before I bug the tuner too much.

Pure600
FBO
93 Octane
PC Coils
Index 12 injectors


I've been fighting a low pressure fuel system issue where the car would die when warm and wouldn't start back up again due to no low side pressure. I thought it was the EKP so I replaced it and so far haven't had the problem reoccur.

I see in the log that between 5200-5300rpm the boost starts tapering off and trims start flying along with a big throttle closure. Not sure if that's a base map quirk or a bigger issue. Any opinions appreciated!

Hi,

I want to improve my performance but before I start, I have a 28A0 code that I am trying to troubleshoot. The car is a bit rough at idle sometimes but seems to drive well enough.

I have logged it using MHD to try to find out what’s happening.

The main thing that’s odd is on WOT, my target boost stays at around 8 PSI and actual boost hits 16 and then declines.

It would be great if someone take a look and see if they can suggest what’s happening. What does target boost max out and actual follow a more usual pattern?

Can you flash Stage 0?

Load actual is way below load requested and timing corrections on cylinder 4, apart from that looks ok to me.

Did my first logs. Stock 1M.

Looking for help interpreting results. Car pulls really well in stage 0 and stage 1. My butt doesn't detect any issues. But the logs look like there is consistent cyl timing corrections. Pulls are in 3rd gear from 2000 rpm.

Am I safe?

I would pull from at least 2500rpm as MHD suggested not 2000rpm.

Corrections are probably due to the 91oct fuel. You could try 93oct fuel or add E85 to confirm.

Have you done your plugs/coils?

I only have a Monitor licence at the moment but I could get the full licence and do the flash.

I just thought it would be good to get it running properly at stock first before changing software.

If I recall correctly, you don't need a map pack to flash stage 0.

Stage 1 and up you do.

Ok, will log again from 2500 vs 2000.

I'm in CA, so 91 is the best I can normally get.

I have not done plugs/coils yet, but plan to next week at my next service.

Is there anything I should concerned about? Is it safe to run Stage 1 or Stage 0 in this state?

Thanks again!

I'm back to sorting out my N54 swapped wagon. FBO , relocated inlets, I was driving it without the JB4 because I was having some issues the logging with protools but it turns out that my Cas is still reporting the 328 vin so it doesn't default to 335 logging items.

I put the JB4 back on so it can at least give some feedback through there. I did pulls on map 2 and map 5 and I'm scratching my head why it never requests more than 10 psi? Should be like 15? Seems lean too. Anyone here good with the JB4? I have an account for N54tech but no idea what my login is there.

No worries,

Yes it's safe to run Stage 1, apart from the timing corrections looks fine.

Good idea to do the plugs and coils though. Worn out plugs/coils can also cause corrections.

Ok found 100oct. Added 5 gals of 100 to about 4 of 91 oct.

Moar power. But same cylinder timing corrections.

Sounds like I defn need plugs and coils.

Thanks.

Not to stray too off topic but found my "mysterious" cyl 6 misfire. All of my plugs were finger tight.! I installed new NGK Iridium plugs and torqued to 23nm. They have a large crush washer so the only thing I can think is that I hit the torque spec as I tightened and crushed the washers but they were actually not completely torqued. I guess a good rule of thumb is to drive a few days and then re-torque plugs!

Hello everyone, I was wondering if anyone can take a look at my friends log. It's a 2009 135i FBO stage 2+ on an e50 tune, upgraded inlets and outlets as well as an upgraded LPFP. Here is the log

lol, post a log once you've done the plugs and coils. You will probably still get some corrections but they should be significantly less, hopefully.

Assuming your on a custom tune,

I'm guessing DME is closing throttle as a result of which boost is dropping due to load actual taking a nose dive from 5k, no idea why it's dropping so much. You'll have to send the log off to your tuner and ask your tuner.
