Arrow Cobb e85 Datalog!

Did a couple e85 Cobb (e30 race map) datalogs.
FBO
About 35% Ethanol to 93oct
Traction fully OFF
3rd gear 2500-6XXX
I'm still getting some timing pulls.

Can someone take a look at my logs and see if anything looks out of place?

LTFT & STFT #'s look like there is still some room before maxing out my fuel pumps, does that mean I could add more e85 to maybe help eliminate timing pulls?

Thanks

I would add another gallon of E85 to get those timing corrections in check. Remember unless your checking the Ethanol percentages in the fuels yourself you never know what random mix your going to get.

Hey man, i looked at your logs and the throttle closures have definitely smoothed out nicely. Adding some more ethanol should take care of those timing corrections. Your STFTs and LTFTs have plenty of room so i'd throw in 2 more gallons of e85. Keep mind that at this time of the year "e85" is usually closer to "e70" because they are using a "winter blend."

would be nicer if you could just plot them and upload the picture so everybody can see those instead of downloading it...

Sorry , I find graphing it in excel is less informative/ sometimes unreadable.
IMO, i find it easier to read in excel format, you can highlight/hide/delete/etc columns and rows you dont want to look at or pay special attention to.

Same here. I'll graph it first just to see if anything jumps out at me, but then i'll just look at in spreadsheet form.
