Depends on how bad it is leaking and how much fuel you are OK with being in your oil.

seriously I thought it was just leaking into cylinder when off throttle it looks like it does close but then leaks a little randomly cause afr stays close to 255 but I didn't think it leaked into my oil do you think a good injector cleaner can help ? from my log does mine look bad?

When the car is running, you are correct. When you turn off the car, the fuel leaks out of the injector as the fuel system depressurizes, around the rings and into the crankcase.
This is why one of the ways to check for a leaking injector without actually pulling injectors and looking at them is to smell your oil for signs of fuel. The good news is that a lot of it boils off as the oil heats up...but it still isn't good for a lot of seals and other things in your engine.

I doubt an injector cleaner will help.

You definitely have something going on with AFR on bank 1.

Hey Guys This is my first time tuning and my first time posting on this forum I got my 335i about 3 months ago and have done the following:

Walnut blast
New plugs
Replaced both VANOS selenoids
Upgraded charge pipe and BOV
New oil change
Both Turbos were replaced about 8 months ago under warranty

I am pretty new to reading logs and would love some help as I don't things are running right. I will say that I am in Canada and I know our fuel is not that good and this was on MHD map 7.1 stage 1 with normal 91 octane. I think maybe I should switch to the ACN91? I use shell V-power BTW. I have Cattless downpipes and am getting them installed tomorrow. Anyway here is my log and I would love some help. Thanks alot guys

You have a lot of corrections.
I would highly recommend ACN91 map and relog. Also do a 3rd gear pull.
do you have access to e85?

[sbuchana12]

E85 is not local to me at all. but I would be willing to travel to get it. If i do a 30% mix do I need to upgrade my maps to e85? or a new fuel pump?

Nope. Dont switch map. Just add a few gals of e85, and log again. This will tell you if its the fuel. Then going forward if you wish to run an e blend tune, then thats your choice.

Just flashed the JB4 pump bef on mhd, menu 4/2, map 2. was previously on stage 2+ mhd map menu 4/4 map 1 but top end wasn't there. here are logs after i flashed the jb4 pump bef and reset adaptations if someone doesn't mind reviewing

nowe I'm really lost I made sure traction control off have the alpina flash but getting torque limit 4 in 3rd i know people get it in 5th bUT 3rd what's wrong with my car plus I had bad timing pulls on cyl 5 out of nowhere not sure if fluke

I think the TC is engaging, together with throttle closures, in an effort to limit your boost, as you were over target. Also there was a boost spike when the RPMs were dropping, which should not be happening.

I'm guessing either the boost solenoid(s) are flaky or maybe you have a binding wastegate.

I just changed one pressure converter had other checked and changed charge pipe the turbos have 10k on them i was told it is normal on throttle closure for diverter valves to catch up does this mean i just need to upgrade my diverter valves or switch to a bov setup and I know cyl 5 is a problem cylinder for most but does that look to be bad coil I guess my overall question is this map safe to run i know my hpfp looks good my lpfp I'm not sure I also am running more like e40 or e50 now cause I added more to make sure I didn't blowv anything up and I am going to slowly drop my ethanol level until I hit e30 as long as timing stays good thank you for the quck response I was Def nervous

Hey guys so I have been logging and tried out for my first time MHD e60 and my fuel low pressure fell below 50 I'm on stock fuel pump I know that's bad so should I try and waste all my gas now or is doesn't matter... the damage is done?

Note: My logs looked fine on e40 and wanted to up the boost so I tried e60 I won't do that again.. seeing my fuel pressure fell below 50. Looking into fuel it stage 2.

why waste the gas you did no damage you just can't run that map well shouldn't run that map and once again that is only at wot that you would run out of fuel you could just go back to your e40 map which should be ok with the e60 in the tank

If you guys wouldn't mind checking out my logs, this link has 3 different pulls in 3rd gear. I am running 93oct, ER fmic, catless dps, and ER charge pipe.

Great logs good job

I am looking at going to stage 2 or 2+ what values do you look at to see how well it is performing?

One to look is lpfp psi, which is already dropping to high 50s. Likely will not make stage2 wo upgrade.

Looks like you have a massive boost leak. While checking all your connections, double check all vacuum hoses, solenoids, etc. as well.

can someone please look at my logs please... Ive notice that my hks bov is not as loud as it use to be this is v7 anc91 stage 2+ http://www.datazap.me/u/jlcf22/log-1...og=0&data=3-21 http://www.datazap.me/u/jlcf22/log-1...og=0&data=3-21

What are your mods?

Other than timing corrections, everything looks to be in order.

Curious what FMIC you're running though. Between that and/or adding a bit more octane, you should be good.

In the stage of doing so, just replaced pretty much everything. will go over them all.
