Start collecting spare gas cans... i've got 4 5 gallon cans i bring with me for my hour drive to get E85. Lasts me about a month.

I can get 55 gallon drums from work anytime I want so I'll just use one of those.

That's legit --- I was considering buying one of the drums w/ a pump handle and all, but my job's putting me on the road so that's put on hold for now

Looks pretty good, you had timing corrections during(what i assume is the 2-3) shift but corrections during a shift aren't a huge concern. You only had one correction during the actuall pull which is good.

Did you have traction control completely disabled? You had a throttle closure immediately after the 1-2 shift and another small immediately after that closure. It looks like they were TC related but without knowing if TC was on or not i can't say.

Like all Cobb logs your AFRs are beautiful.
Thanks rader1, that was a stage 1+ aggressive OTS map v402.

I did 2nd > 3rd and let out at the top of 3rd. TC was completely off.

Ahh, I was guessing based on boost.

Your log looks pretty good. Like I said, you had a throttle closure but it wasn't a terrible one. If you're not already running the 4.02 beta maps then I suggest to give that a try.

Looks like your car seems to like the stage 1+ aggressive map.

Are there any specific e85 maps coming soon for Cobb Ap? I want to run e85 so I'm leaning towards procede because of the numbers they make with just dci and e85. I know you can mix in 1-2 gallons of e85 to your tank with the Cobb, but how much power would that yield on stage 1 aggressive? I would love to go with cobb over procede just because of the ease of install. However at the same time I don't mind spending an extra 30mins installing to get a specific map for e85 that makes ~410whp.

Don't fall victim to marketing. I can post up a 480whp DCI only dyno if you would like. The car dyno'd 478whp stock though.

He is making great power but hype is hype.

With ATR available, I would think that people with a high interest in that would make their own. Some timing tables have been posted here that take advantage of at least some E85 and seem to work pretty well. Just log for knock to make sure you've got enough E85 in the mix.

COBB E85 maps are on the horizon & the Vishnu thread you're talking about where they made "410 WHP" on a tune, DCI + E85 illustrated no stock tune baseline, making it very easy to manipulate the dyno sheet & create the perception that the car put out FBO power on bare minimum mods.

And personally, I don't care how Shiv made 410 WHP on just a tune + DCI, but it must be AWFUL for the turbos making that kind of power with the restrictive OEM catted DPs still in

I used ATR to increase timing with 30/70 E85 mix and picked up 15-19 WHP thoughout most of the rev range over the OTS Stage 1+ agressive map. Used the Barnhill virtual dyno which has been very consitant in delta's between maps. I'm happy with it, no timing pulls, didn't have to increase boost, and not running lean fuel trims. I'm sure I could probably add just a bit more E85 and increase timing a bit more, but I'm satisfied with the tune now.

Are you going WOT? Also you need to add timing to your logs nothing is showing up on your attachment.

Are you getting fuel mixture codes with your custom map?? I've gotten fuel mixture codes a few times when mixing in ~3 gallons of E85, but it has had no impact on the performance of the car (no misfires, shuddering, etc)

Thankfully no. I'm near 24% in STFT so I'm near my max comfortable zone for fuel. I doubt it helps any but I also add a couple of oz of marvel mystery oil with each fuel up if only for lubrication purposes.

I'm using the Cobb Aggressive v401 Beta map on my 08 135i.

Filled the tank to 3/4 with Cali 91 OCT, and rest of the 1/4 tank with E85. Approx 10.5 Gallons of 91 OCT & 3.5 Gallons of E85. Should be about 95 oct in the tank. It's my first time running Aggressive and I can notice a difference vs the sport map.

I've read that it's fine to use as an octane booster and that's exactly what im
doing.

You need to log LTFT's and STFT's to make sure you aren't maxing them at (34%).

So can I run 3/4 tank 93 octane and 1/4 e85 on stage one aggressive?

2 gallons of E85 mixed with 14 gallons of 93 would yield 94.5 octane. That should be plenty to keep your car running strong on S1 Aggressive mapping. Any higher concentration of E85 will have negligible gains.

1st part is right, the bolded stuff isn't -- As of right now we're good to mix up to 25% (4 gallons). Piggy's are running 50:50 blends so there's no diminished impact of E85 until you start putting in more than 8 gallons, we just need for COBB to integrate E85 fueling to capitalize on those gains

What he's referring to is the amount of e85 required for the car to run the aggressive map to it's potential. He's correct there. If we were talking ATR and an e85 map then you would be correct.
