No, generally timing being pulled is bc not enough octane (and or possibly plugs or coils starting to give up). The boost targets not being close to actual is more likely the cause of some coupler.

First basic log with Stage1+ and not much else. I would think it would be able to go to a 95octane map.. especially with some e85? Maybe just 1.5 gal to start and see..

I have noticed on cold start that the idle has a few slight misses. Maybe the coils are at the end of their life. I'll check for vac leaks and pull another's log if I fix anything, otherwise will look into the ignition.

Hey guys I'm definitely having some issues can you guys give me any pointers.

07/07 335i Charge Pipe and Blow off Valve with alpina trans flash and muffler delete are only mods. Tune is a Stage 1+ MHD OTS.

Id at least get a spare coil and plug and see if the individual cyl retards are less on a hole that has fresh Coil/plug. In theory, if one is tired, that should make that cyl clean for a while..

All that depends on how close someone might be to the map being too aggressive or not.. but once you get a certain map and fuel blend dialed in, it should be consistent.

It really only looks like you had it floored for about 3 seconds.. thats kind of hard to get much in the way of boost curve especially in second gear. Try to start in 3rd and go to 4th at least to 5000rpm.

It seems there is a good amount of variation in the AFR .. more than I would think an OTS map would do. I would think it would be more in the 12s.. It seems to be adding fuel via short trims when it is already pretty fat. Depending on how many miles there are I think you need front O2 sensors at least.

I would also set your Waterpump option to sport. It will get the water temps closer to 180 and oil temps about 215.

You also might not have the latest HP pump. IT seems the LP pump shows only 145. I know the last time I got my HP pump replaced (on the 2007 n54) they had to replace the rail also bc it had a new sensor. And I think that was a LP sensor..

I have this other log in 3rd dont know if it makes a difference.
http://www.datazap.me/u/jelias17/log...0&data=3-14-23

Front O2 sensors would be on the downpipes right? Ill get another log in and post it soon, and you think my temps are a bit high? what are the values more or less they should be at? My LP fuel sensor is bad, i keep getting a code for it, thats why it reads the same value constantly, I compared my log to the one you posted on the same map and i saw the numbers were lower and fluctuated I get 145 all the time no matter what. My rail pressure seems to be up just like your log.

You have a 2013 N54 correct?? Im still learning about the car and love learning new things everyday about the N54 and how it works. Thanks alot for the help.

Yep, If you arn't going with Ethanol now it should not be an issue. LP pumps rarely die but they do add load to the HP pump. I would try to get it replaced.

Anything below 200 is best for water temp. If you set the WP option for sport it will bring it down at least 15 degrees pro. IMO it will make gaskets last longer - which N54s always have probs with.

Yep, No P.

anyone want to take a once over my log. just got car back from getting oil cooler installed, VCG, OFHG changed. Also changed plugs with 1 step colder.

[kisarci]

Looking for some input.
Using a custom flash tune only, full e85.
FBO, inlets, ADE-PI, stage 2 LPFP

So I can't figure out why my car starts to hesitate as you can see on the RPM's.
I feel like everything looks good.
Rail pressure looks good, LPFP looks good, AFR good, all my fuel trims look good, no timing corrections.
The turbo's spools up nicely but gets into trouble when it hits top PSI.
Could it be the map sensor going wonky?
Any ideas? Thanks~

You seem to be getting timing pulled on just about most cyl except 6. I dont think petrol (uk right) is really 91.. or something else is going on.

Coils next I would suggest.

i'm running Chevron 92. I live in Canada but often get gas in the US as i live about 10 minutes from the border. Coils are next up on my list. In the process of selling/buying a new home so trying to save up as much cash as possible in the meantime for incidentals.

[Omni159]

can I get some feedback on this graph. COBB IC, MMP inlets/outlets, and VRSF downpipe. boost taper seems pretty aggressive as it closes in on red line. can anyone enlighten me on what dictates boost targeting is a static figure based on the map and throttle or is it more variable than that?

Look at those humps which I've marked right in the meat of your 3rd gear pull:
http://datazap.me/u/kisarci/dk-111-w...37&mark=88-102

Not to mention the AFR variance in 3rd after 4644 RPM and pretty much all of 4th...I haven't seen heights that scary since the last time I was on Splash Mountain.

You need to get your fueling squared away immediately...I would start by looking into your PI system. What are you using to drive that unit?

Who tuned this? It would be worth a look by them as well.

Don't worry about "boost targeting" just yet...looks like you have a boost leak or vacuum issues; much bigger issues to chase down first.

If you want less taper you need to run something other than a stage 1 tune...you'll need something custom and a lot more octane for max benefit from the parts you have installed.

Also, you gotta log more pertinent data next time. This pull really only tells half the story.

I seem to recall something about chevron 92 in .ca being pretty sucky. Try some other like BP or shell.

Thanks Cobra ill work on tracking it down. any suggestion as where to start pressure test or start replacing vac lines? Also may I ask what in the log pointed you to boost leak / vacuum issue? By bigger problems are you mainly referring to the boost leak or do I have more to be concerned about? Thank you for your feed back.

These two vacuum lines are the worst to leak,

this log was US Chevron 92. In canada i usually will up 91. Once this tank is done i'll try a log and see how big of a difference in correction i get.

Hi guys!
I saw that i had a shadow code related to my HPFP so I decided to pull a log. This is my first log so Im not sure what Im looking for, but it seems to me like the rail pressure is pretty high? I noticed that I had some timing corrections over all cylinders and also that my boost curve is all shaky. Does this log looks normal to you? Im running MHD stage 1+ 93oct with a mishimoto IC and a BMS chargepipe, rest stock.
http://www.datazap.me/u/oggez/log-15...ta=12-14-20-21

Edit:
I looked at my second log that i made like 5mins after the first one and that one does not have as much timing correction. Is this normal that timing corrections differ this much between each pull?

Eh, IDK, looks like its pulling timing pretty bad when IATs go over 105. But on your first log it was doing it at mid 90s. I would try a little more octane or going to a 91 map and see what happens. Looks a little rich but I would not worry about that until timing stays solid. Actual output values look good when its not pulling timing. several 600 readings,
