Looks good from what i can tell. I guess the first log was leanrning thats why the jumpy boost.

I think you can go from the 33% E85 to 40-50% E85 and even try map7 if the LPFP and the HPFP can keep up.

I did a dyno baseline last Wednesday and here are the results.

Mods are in my signature and running 6 gallons of E85 + 10 gallons of 93

Nice! Could use a little more E85 for timing, but looks good! Out of curiosity, do you get a vibration/grainy noise if you go WOT in 4-6 below 3500rpm? I get a weird noise at full boost and low rpm and believe it is the clutch, transmission, or DVs.

Looks pretty good for STD numbers. +1 on a bit more E85 for the map 7. I think I'll shave maybe 1/2 - 1psi off the higher RPM map 7 targets as it looks like stock turbo cars are having a hard time hitting them.

Not that I recall but I'll try to listen in on this now.

I was messing with some experimental firmware and had a bunch of diverter noise and along with it came that grainy/vibration sound. I ask because you have upgraded DVs. I didn't think this sound could be related to DVs, but maybe they are fluttering. I don't know.

Still autotuning I'm guessing. Boost is rising w/ every log.

All 6MT cars do this. It comes from producing excessive torque low in the RPM band. I think it's something torquing over and vibrating on a subframe or something. Possibly the diff/diff mounts. My previous 07 did it once it started making a lot of torque. My 09 does it as well as any other tuned 6MT 335 I've ridden in. A lot of people don't load their car up down that low and some just don't even notice it until you point it out.

Yep. Maybe input shaft, clutch, etc. It is definitely noticeable and sometimes louder than other times.

Yeah it was on SAE. I changed it to STD but Uncorrected is about 507. I am not sure which one you used. Either way they are both a lot and I love it!

i recently noticed it too under heavier throttle at the beginning of boost onset at lower-to-mid rpm. It's a prominent resonance

Do you have DCI? If you do and replace it with the stock intake, the sound virtually goes away.

I definitely do have a DCI. If that is the case, that is more reason to suspect that it is a diverter valve issue since DCIs will make it much easier to hear the DVs. Maybe they are fluttering...

Rudypoochris & bmw loe; did you figure out what your fluttering/noise issue was?
