Actually hes wrong, some of us are running 50:50 E85 using ATR as well

WHAT!? Do tell!!! How are your STFTs? The most I've seen is just north of about a 30% mix before the trims Max out

I've never used the data log feature in the Cobb AP before, what are the variables that I should log?

I never bothered with data logging because my car has been running smoothly for the past year on the OTS Sport Stage 1 maps.

But now, all the buzz about the amazing properties of mixing E85 got me to want to give Aggressive a shot (as I do not have access to 93 here in Cali).

Use the default logging channels and be sure to have STFT and LTFT marked as logging channels.

Sorry I wasn't used to the format you have it in. The car seems to be running fine to me. It's definitley hot where your at and I believe thats why your only seeing 2 max degrees of timing where I'm sure agressive should be around 4, but no timing drops which is good.

So pretty much if I want any real gains with e85 I need to stick with procede or jb4, until Cobb comes out with dedicated e85 maps?

You can run E85 & 91 or 93 octane blends just like PROcede and JB4, you just have to get tuned for it by paying for a protune, an etune or by making your own map using ATR.

I'm waiting to empty this tank and I'll get some logs of 50:50. Meth helps to reduce fuel trims 👏

Ahh, I completely over looked the HFS-4 in your sig. Meth just may have to be our saving grace until Cobb releases those fuel scaler tables. I'm contemplating a 50/50 93-e85 dyno tune....

I have logged a few 2nd and 3rd gear pulls. What do I look for in terms of numbers?

You want the fuel trims to be well below 34%(Max fueling.) Most people(including me) want to see low 20s.

Save a copy of the csv as a txt and then post it up as an attachment and I'll go through the log with you.

You should be fine but expect run a fairly high concentration of meth - like 80/20.

Would love anyones thoughts on this log. Timing is being pulled on one cylinder. Ill check the basics, new plug and swap the coil.

I will relog to verify the one cylinder is the culpret.

Anyone see anything else odd?

...and i will turn on the fuel trims for next log. Anything else i should do?

Sweet! This is a a pull done in about 60 Degree temps, traction control completely disabled, 75% CALI 91 OCT Shell & 25% E85 Chevron.

Map has been installed for a day, with a handful (5-10) WOT pulls done, so adaptations should be set.

I started logging at a stop light, and did a 2nd & 3rd gear pull.

Would you please check if I'm running safely with this map & mixture.

Sounds like you know what's going on
Aside from the timing corrections in no.4 everything else looks good.

Timing corrections don't necessarily mean you have too aggressive of a map. If you are seeing multiple cylinders getting corrections together then its what we look for but little random corrections are typically just noise. The sensors here are too sensitive and you should learn to weed through the "noise" and find the actual events.
