Since we're talking about E85, does anyone know what I should be looking for when I log to determine if I can add more E85? Is it FOL? Is there a range it should be within?

Usually I run 70 for fuel open loop

That's what I have it set at but when I'm looking at a log what should I look at if I use 3 gallons vs 4 gallons for example

Combination of hpfp, trim, and afr. Those 3 things will give you a good idea for what fol should be. Lets say you run e40 mix and avg ign is .5. Yet those 3 parameters say you have room for more e. At that point more e wouldnt give any benefit.

That depends on the true % of the e85

My average ignition is usually around 1.5-2. I use 3.5 gallons of E85 and the rest E93. I'll do a log tonight or tomorrow to see what my HPFP, Trim, and AFRs are and I'll report back. Thanks for the help!

I can look at the log and help you. You really need a e85 tester.

Thats what I usually do also. Last time i had about 3 or 4 gallons of 93oct and put in my 7 gallons of E85. Then I was driving back to my 93 gas station by my house and I got on it on map 2 and it stumbled hard and through a bunch of codes and died. I cleared the codes and it still wouldn't start until i let the ecu power down all the way. Then it started and ran fine since...

Chart doesn't look right to me. Boost doesn't hit 12 but car feels strong. Thoughts?
