I have been hearing a slight bit of rattle but its like 10% as much as most stock 335i's. The weird part is my boost doesn't oscillate on my Wedge E60 tune nor did it oscillate on my stock tune. I am running a 3.5 BAR Tmap with the option enabled, idk if that affects anything.

Thanks for looking! What indicates a possible leak at the wastegate? Is there anything I can do? What amount of post shift timing correction is acceptable? Sorry for all the questions...

Hmm, I have never thrown any codes on my car but I see what you're saying with the AFR. So does it do any good to reset my adaptations since I was running Cobb for 5 years and now just switched to MHD? I didn't know if the car learned a certain behavior with the Cobb tune and maybe that is why MHD is logging some odd numbers. Then again, I admit that I have been lazy with logging even my old tune since 2013. One of those things where the logs looked good back then and I didn't re-check to see if things had changed since map development for Cobb ended and I never switched maps.

Kind of slow to build boost could indicate the wastegate issues, nothing I would worry about unless they make an awful rattle. Could also be if you have the rattle fix on it could cause this delay as well.

Also looking back I do see some timing corrections across a few cylinders, may want to try some new gas and do another log.

[MikeS300]

So here are some new logs back on Stage 1 93 oct. Does this look better with how AFR returns to 234.95? The only changes I made was disabling the exhaust burble and resetting all adaptations except throttle. My theory is that the burble setting may screw with returning AFR back to 234.95. Also, with automatic logging for some reason MHD would stop logging at the end of the run too soon and maybe I could not see the return of AFR to 234.95

I do have the wastegate rattle fix set at 70% although my wastegates have never rattled, I thought maybe implementing the fix could help them from wearing prematurely. Although I could never figure out if that made any sense...

The gas in that log was BP 93 which I switched to because the 91 I was using had a lot of corrections also (log below). So I'm not quite sure what the deal is. Last summer I wasn't getting much if any corrections.

Yes, burble option dumps fuel to ignite and that effects AFRs. I was going to ask if you had it set, but they look normal in these logs. The early lean is during spool, so likely either spool tables set that way or lean spool mode is enabled. I'm not a huge fan of it, but lean spool is the factory setting.

Any way you could do a 3rd gear pull and log that?

Thanks for the comments!! I ran a couple logs today (79*F). I believe this is the third of the three. They all look very similar. I noticed small amounts of timing is being pulled across a few cylinders. I don't see any fuel issues - am I missing anything?

The previously posted log was 2nd gear, I wouldn't put a lot of stock in what it shows. Use 3rd at a minimum and start lower (~2500rpm). There are quite a few corrections and on most cylinders for these. If you're working with a pro tuner and that is only v2, it's early in the game. You should be showing them your logs, not us

Another question, what is the difference on MHD Stage 1 vs. 1+? Does the 1+ just target higher load and boost because the assumption is that a FMIC will keep IAT much lower than stock? Are timings otherwise the same?

Cuz I'm bored or because I was curious what the obvious differences were myself, did an overlay of your stage 1 and stage 1+FMIC logs.

1+FMIC requested +20-25 load, yields about +15-20 actual load and +3-4psi of boost. Timing is 0.5-0.7° lower and AFRs are 0.5-0.7:1 richer, both of which may just be from stepping up in the load columns. Those differences are across the board. WGDC is +10-12% on 1+, max of 55% ~5200rpm and fuel trims are pulling even more out 3500-4500rpm, but still have room (-20% at a max). Unsure if there are tune changes that effect it or just a reaction to the richer AFR and/or adaptation reset between them.

IATs are +15°F by 5000rpm on 1+FMIC, but starting IAT on 1+ log was 9°F warmer too. So, the IAT rise wasn't tons higher up to that point, but that's a very short span. Had you kept going to 6000, Stage 1+ IATs would've been significantly higher, probably >130°F, based on the on the rise from Stage 1 log from 5200-5900rpm. It's not uncommon to see over 140°F IAT with stock FMICs and raised boost depending how long you stay on it. Not that there's much point going over 5200-5500 on stock turbos, but multi-gear or back-to-back pulls will get real warm, real fast without an upgraded FMIC.

One -3° correction in each log, different RPMs, but both on cyl 4. As long as they stay intermittent/random and -3° or less and recover immediately, I wouldn't be too concerned. Not that the 2 logs I looked at is a big sample, but essentially nothing changed drastically in that department with the increase.

For off-boost daily, just about any map isn't a problem unless it's for high E85 content, just mind the IATs on this one.

just picked up a VRSF 5" Stepped intercooler, wanted to do a log before the install. Still new to reading logs, anything in this log that should cause some concern?

Lots of corrections across multiple cylinders. Any way you could add a splash of E85?

E85 is hard to come by where i live. I was planning on doing coils and plugs in the near future, would this help with corrections

Thanks RSL. I do have a tuner and asked him some specific questions for which I am awaiting a response, but I figure it always good to have considered all avenues of assistance..

It is, but a pro tuner should have no problem picking out anything that needs attention and is extremely early in the process. Give them a chance to do their thing. Spool AFR could be tweaked and a lot of consistent corrections, but they should be able to dial that all in with another revision or two.

Thanks RSL for the comparison! I think I will stick to the stage 1 93 until I decide to upgrade my intercooler. I'm doing my first walnut shell blast in a few weeks with another guy in my town who just so happens to own a 335i and has already done his own blast. I think this should help smooth out some logs.

Those shadow codes are normal with MHD tune. Did you get the 30FF on this pull? You should post a pull with the normal and default variables instead of the vanos ones so we can look into that.
As far as vanos, start with cleaning, if no improvement, replace. Plenty of posts on here how to do that and step by step diagnosis and treatment.

I didn't get a 30FF code. I ordered new VANOS and will install this weekend. I actually have a number of parts I'm replacing.

Battery - tested at 11.4v + general maintenance
Boost solenoids - general maintenance
Vacuum canisters - general maintenance
Vacuum lines - general maintenance
Coil packs - miss fires detected on cylinder 3 & 4
Plugs - same reason as coils
VANOS - replacing because of code


I did recently get a 30FE and 3100 at the track a couple weeks ago. Over boost issue.

Here's another log in 4th gear - 2600rpm to 6800rpm. More parameters logged.

Hey guys,

I just flashed the e40 tune after seeing solid numbers from my fuel pumps and deciding they could take some ethanol. I was hoping someone could take a look at my logs and tell me if I have any serious problems keeping up with the octane level.. I am also having boost problems, mid is reporting that I'm only hitting 10psi but the car feels very quick, like significantly quicker than 10psi. I get 30ff codes if I ease into the throttle and then punch it about halfway to WOT. Sound like anything you've heard of?

Here are the logs:

3rd WOT:http://www.datazap.me/u/cj250mills/3...og=0&data=3-22

4th WOT: http://www.datazap.me/u/cj250mills/4...og=0&data=3-22

5th WOT: http://www.datazap.me/u/cj250mills/5...og=0&data=3-22

Thank you so much for taking the time.. seriously, much appreciated!

Thank you so much for taking the time.. seriously, much appreciated!

Regardless of what it feels like, something is going on. Requesting 180-190 load, getting 120-138 depending on the gear. 3200->4200rpm to get the 10psi in 3rd is forever and 75-96% WGDC (essentially fully closed) through the entire pull. The 30FF seems legit.

E82MSport If you have INPA, you can try resetting VANOS adaptations. Both move around a good bit, but intake has a larger deviation. MHD might actually reset it now that I think about it. Not sure how many miles, but never hurts to replace or remove and clean the solenoids once in a while anyway. You'll want to reset VANOS adaptations after the new solenoids either way...
