BuraQ, Thanks for replying. I know you know more about ethanol and the Z's fuel then anyone here. I noticed the DCT does shift slower sometimes and it doesn't seem like all the power comes back on instantly but takes a second. Is this because there is no back end flash with the cobb's OTS maps?
Yeah I can def feel waste gate oscillation, I'm assuming that can be fixed with a dyno tune?
Do you have plans to push your Z past E70? Do you think Running full E85 is an option on the stock fuel platform?
I was going to have Anthony at AV Engineering Tune our Z next month. I've been waiting to see what results you've found. So your running about 11.5-12 gallons E85 and then then the rest 93?

It can be fix yes on a dyno

Your flash only tuned, back end flashes are for piggyback tunes. It does not apply to you unless you go with a piggyback setup

We have no plans right now at the moment until the injectors have been swapped out for the latest index injectors. So we wont know anything until we get there. So far it can hold up to E70 fuel effectively on stock fueling system

10.5 gals of E85 and 2.5 gals of 93 octane

Ah gotcha. Well looks like next month I need to find time to get it to a av engineering and let them tune me on at least e70.

You have stopped at E70, because of the injectors? Was the Duty cycle exceeding 100%? What made you stop at e70?

Also what company will you be going with for these index injectors? Have an idea on the cost? I'd love to be able to run 100% e85 and be done with the concoctions.

Anthony at AV Engineering should be able to answer all these questions for you. Respectfully, I answered all that I am comfortable with in answering about the Z4
