E85 question
You bring up a good point of the 14.4 vs 14.7 stoich for E10 however... Can you give a quick explanation of why you don't like setting pump E10 to 14.4?
Many people on the HPT forums and other places I have read are using the 14.4 to 'split the difference' of E10. I personally am running 14.4 stoich and I have my tune dialed in perfectly at cruising speeds using dynamic airflow till 3K. My trims seem to be much better using 14.4 over 14.7, however I never did a complete back to back comparison. It could simply be because I have spent more time tweaking the 14.4 settings.

It sounds like you still have some gas left in your tank and it has skewed significantly the amount of ethanol in the fuel, hence why it will not run. I'd try and get that fuel out, put in straight E85, adjust the stoich to E85 for an existing good tune of yours, then dial in your MAF/VE, etc...

well I tried multiple tunes, that I thought were good, but it seems to love my original gas tune so naturally I was stumped. Thought e85 required more injector volume yada yada. Then I gave it some gas, about 60% throttle it just revved up and didn't really go anywhere, kinda like you hit the rev limiter.. So I was thinking well, that right there is the e85! need more injectors on or around that throttle response, but my pe was set at like 35% and coincided with my stoich... Idk, I'll fill up and let you guys know, bringing my laptop with me in case it decides it wants to go 100% e85 on me with the gas tune. If you want to see the e85 .hpt file I would appreciate the look over.
old thread i know but i've just been doing alot of reading lately...
Area; question...
Why is it that you say you set your e85 stoich at 10.4 because that's a good avreage, but recommended AGAINST setting stoich at 14.4 to make up for the average between e10 and pure premium?
Not trying to ruffle any feathers here, just curious. I am planning on switching to e85 very soon and as far as i had read (until now) the stoich needed to be approx 9.7
Just getting all the info that i can. Thanks
