So, first ever MHD log This was a hard pull in 3rd until I caught up with traffic - hard to find an empty road anywhere around London! The car has an Evolve Stage 1 map and not a lot else engine-wise. The only thing I'm slightly concerned about is the throttle closure around 3k - presumably this is because it overshot the boost target? I get very occasional 30FE overboost codes on hard uphill pulls, so I'm wondering if there's an issue with the wastegates or the actuators...

Stage 2+ 93 Oct. V7 map. I recently had the fuel pump message pop up on my idrive and figured I should take a log. I'm leaning towards hpfp since I have a stage 2 lpfp that only a couple months old. Any help would be appreciated.

Mods are in sig, but RBs, Inlets, dps, FMIC, N20 MAP sensor, 93 octane running V7.

Thoughts?

Anyone? Bueller? Bueller?

Go back and take a log of ONLY 3rd gear 2k-7k then shift in 4th for a couples seconds before letting off. That's a proper log unless advised otherwise to chase a different problem down.

Best advice I can give you is research the custom tuners and get a custom tune asap! I personally would never run an off the shelf map with upgraded turbos and inlets. You have timing corrections in multiple cylinders and are over boost target most of the time. Good luck!

Hmm, I'm not quite hitting boost target on 7.1 ... Is this a boost leak or just due to turbo backpressure at high rmp (I'm stock catted downpipes)?

[Theador]

SoMe logs here if anyone could pass an opinion: I think it's showing timing corrections as I'm exceeding load target and boost target. Any ideas why I'm exceeding load and boost - if indeed I am?

Looks pretty good. Your LPFP and rail pressure are both fine on this run. Only thing that is a little weird is your STFTs are a bit asymmetric comparing between banks, but that's not a big deal right now. If they continue to widen, it'll be time to look at fueling components (thankfully, it's subtractive correction right now anyway).

without supporting mods the map is designed for you are definitely going to leave a little on the table.

I'm 100 percent ok with that, in fact, the car feels good. I just want to make sure I don't have a hardware issue that I need to address (like a boost leak).

Thanks for the reply. I'm starting to think my other bank of injectors are on their way out. I have been getting some rough cold starts and hesitation again.

First proper log here: http://www.datazap.me/u/zero2sixtyz/...=0&data=4-6-23

Not matching boost targets in higher RPM range... boost leak?

07 6MT, VRSF charge pipe w/ Tial, catless DPs, and stepped 5" FMIC, running v6.1 stage 2 93oct.

looks like the boost target is a little too high at higher RPMS and the actual boost has a litttle too much tamper up top.

based on timing you are running gas not e85, if so your LPFP is on it way out.

You are mixing E85 already to be running the 93 octane variant in California correct?

That difference is too small to matter IMO. Or to determine if you have a leak.

ahhh alright.. Will do thanks for letting me know.. I got Stage 2 93 oct flashed now... 2011 335is DCT.

I know you told me to start 3rd gear 2k rpm.. I will do that but heres a log of a run I did with stage 2 (not sure if useful or not).. The next log will be as you instructed. This is with e40

I did a proper log 3rd gear 2k Rpm to 7k rpm to 4th gear e40 morning run

Trying to solve a throttle hunting problem. Looks like something is driving STFT's to oscillate at low throttle (2-4%). Not sure which is chicken and which is egg tho...any help appreciated.

Please look at these logs. I've been hunting down a few issues and making progress and I've also been finding more in different areas of concern. Just curious what someones conclusions would be.
