Your logs look pretty good. You had some timing corrections on the first pull during the shift but that's not too bad and on the second pull the corrections disappeared on all but one cylinder. Corrections during a shift aren't unheard of and may not be in reaction to a real knock event.
Cobb AFRs are always strong but yours are some of the strongest i've seen. The AFR trace is as flat as machined straight edge lol

That's good ! We get some good gaz up here in canada. As said previously as I think petro-canada 94 octane (only company with more than 91 in quebec) gaz is crap (mileage is bad and had knock in previous vehicule) I'm running shell v-power 91 + nos booster. Now i'm confident about using octane booster for the track or to run agressive ! Lower temps from tonight help as well !

I still getting used to read datalog from the bimmer as kinda different from my 08 civic si I had previously tuned

EDIT : Anyone know how to trim a log so I can see what virtual dyno give as numbers ?

The best thing to do is just log a 3rd gear pull and load it into VD. VD will auto trim it a little bit.

OFF TOPIC: what were your mods on the civic?

PM'ed

SO cannot really trim existing logs to keep 3rd gear only

E85 mix

I'd like to preface this post by saying that I am by no means an expert on the subject but I did email roundel tech editor Mike Miller regarding E85 fuel mixing and this is what he had to say:

"BMW haltingly recommends no more than 10 percent ethanol (E10) and BMWs are absolutely not designed to run on E85 under any circumstances including a mix.

A BMW dealership would probably be legally justified in denying warranty coverage for damage caused directly by E85 fuel."

He also relayed that he is not rendering legal advice here but that he's seen warranty coverage denied for less.

I'm not trying to rain on anybody's parade, just thought this was useful information to pass along from a knowledgeable source that you may want to consider....

Thanks for sharing.

If I accidentally put diesel in my car and destroyed my engine, I am covered by my auto insurance. Oops.

I know, I guess I was just saying that anyone with a high profile job wouldn't risk their reputation to be in favor of something if that something isn't rated for that specific purpose.

Good info, thanks for reaching out, brought up a good point.

I understand it's two different platform and motor, but in the Evo world E-85 is considered Jesus Juice the link below is why. Just a lil FYI of the wonders of E-85.

I'm on my way to getting my mods together to run stage 2+. Got my catless DP's, and will be getting a FMIC soon. I might track the car a few times this year, in case it makes a difference to your answers.

1 - Was wondering, you guys running 2+, did you have to upgrade your charge pipe?

2 - How about the factory diverter valves? Just want to know if they're necessary to be done, or just a wait and see if they break approach, as (at least with the DV's) I'd read that the stock DV's can often hold up even at the higher boost levels seen with 2+ maps.

3 - And for the air intake, I've got a K&N right now in the stock airbox. How many of you upgraded your intakes too to a Mr. 5 or Helix style (or a CAI I suppose)? Or is the K&N sufficient (which is all that Cobb seems to recommend - a panel filter is one of the choices they said is ok)?

they should hold fine with high boost, if they leak you can always get the forge.

Best would be a Mr. 5 or Helix style if you dont want to go DCI, Injen etc.

Ciao Enrita, thanks a lot for the quick reply!

Couple more questions please:

1 - If my DV's do fail, then I assume I'll just get a code / go into limp mode? Is it ok to keep driving the car then, and stay off of boost? Maybe switch to stock map? Because if I have to go buy the Forge DV's then, it might take a week to get them in, for example.

2 - For the intake, if I haven't had time yet to make my stock airbox into a Helix style and I go to the track with just the K&N as the upgrade, what's the impact? Anything bad, like a possible limp mode? Or just that you can't make as much power as you'd be able to otherwise?

If the stock DVs leak then you'll get a 30FF code. Swapping back to the stock map should fix your problem until you get whatever parts you need(forge, helix, AWE etc)

A K&N filter should be all you need. Worst case scenario you just won't make as much power as you could. Keep an eye on WGDC just to be sure the turbos are working themselves too hard with the stock air box.

The dvs just dont fail like that , there are people that have run stock dvs on 18 psi for years. if they start leaking you will get a limp sometimes and probably on high rpm full boost.
No issues with K&N only. on cobb site is not a requirement.

Awesome, thanks guys.

Just wanted to cover my bases, as with the DP's and FMIC, I'd be using the 2+ maps of course.

A little lag pre-3k is expected since you're still using the stock DPs but have increased the boost. Stage 2/Stg 2+ maps spool closer to low/mid 2k since the aftermarket DPs let the turbos spool up faster

Exclamation Please Review my logs - and proper boost values

Folks,
I've done a lot of reading but I still have little idea what I'm looking at. Can someone please review my log files and let me know if everything looks ok?

I'm stock except for Cobb 43k on car now- did a few runs today 2nd and third pulls - no room for fourth. I'm not sure what to look for, I saw boost values in the 16s on several logs, on the WOT logs (attached) there are values in the 17s and spikes unto 21 ! - is this ok?

Are there plans for Cobb to release E85 over the counter maps?

logs look good considering your IAT is very high. the 21 psi is a boost spike during shift, nothing to worry about , is the sustained boost that counts.

What's average normal IAT values? Would changing oil/plugs/carbon cleaning help?
BTW - this is stage 1 aggressive on shell 93.
Does timing look ok?

There's isn't really a "normal" IAT value. IAT is Intake Air Temperature and it is determined by ambient temps, humidity, vehicle speed, engine load/power output etc..

There's not much that can be done to reduce IATs, an upgraded FMIC and Methanol is about it. Plugs, filters, oil etc aren't going to have any direct effect.

There's only one tming correction on the 1-2-3 gear pull so that's good. The timing itself is LOW, but that's almost certainly due to the HOT charge air temps.
