Next will be 93 tune with E20 to see how they look and if E20 can keep up.

Thanks for sharing! Will you test the e30 tune, too?

I will work my way up to the E30 tune

Awesome! Very much appreciate the pioneering work by you and sd306. Extremely helpful. My car is still in the shop, waiting for the Akrapovic. I will start sharing logs once I get it back.

I'm not sure how to interpret it, but here is a WOT 3rd-5th: stage 1/93(shell 93)

Good timing, zero knock, very nice log overall!

Thanks for taking a look- it's smooth! I must also say that bootmod support looked at some of my earlier logs and they were extremely helpful. I'll share the dyno results on Tuesday in this post.

Shell 93 with E blend (E20) with 93 tune. This is the same gas used in the 91 tune.

Very nice! With E20 it shouldn’t matter whether you mix with Shell or cheaper gas. Agree?

Octane level will be a smidge different between 91 vs 93 on E20 as it’s the ethanol levels that are key but I don’t think there is a huge difference between the two.

Yes, that’s what I mean. Asking for practical reasons. There is a RaceTrac near me that has both E85 and 93 at the same pump. RaceTrac probably not the highest quality gas out there but it shouldn’t matter too much as long as I mix the right % of ethanol.

Bingo, yes you’ll be fine even if the grade is bad, the 105+ in E will make up for it

Looks good for shell 93, i wonder why it's so different from ours. I'd say keep going to whatever station that is from.

Right? I wonder if they have more of a “summer” blend now?

Florida always has summer blend ☺️

Stock rom file is pretty bad. Any addition octane will help this car out a lot. Timing drops a lot in the high Rs

Too much effort refilling the meth tank. I’m lazy. I will just run E20 for now.

How’s it feel? Have any logs yet?

I've posted above 😁 it's great and reminds me of the 335i on full e85, just keeps getting faster at high speed at a ridiculous rate.
