Around here it varies from 79-89 pretty regularly.

Wow.......that is a pretty big difference! Do you have a flex fuel sensor and such installed? Or do you have to switch maps to make the magic happen?

I don't have a ethanol content gauge since I only run E85 however in my dads GTR I have yet to see anything over e E78. We probably get the short end of the stick with that in CA just like our 91.

that's crazy man. Gotta wonder what the "other" content is that makes up the difference. Guess theres no other cleaner way though, pump gas can only be worse.

its like that here in the dmv area too, highest I've seen was around 82% but usually its like 77/78%

If I could get away with running only E85, I would do it. There are not enough places to get it for me to make the switch. And road trips are out of the question.

Full flex fuel! With the new Race Rom II from ECUTek, we are now able to bridge the gap between the 370z and GT-R.

Just finished up GeuaxTigers1 2015 NISMO. We made 499/429 on 91 & with little effort made 648/560 on E78 @ 13 psi. I have no doubt we could of turned it up to match Cy's 677, but the torque was already at 560. Cy can enjoy his stock block record for a while. :) From there we tuned on E65, E55, E45, E35 & E25. This thing is a beast!

What upgrades/additional parts are needed to run flexfuel?

Wish you all were located in fl

Senor, gauge, tune. On top of the fuel system.

So it's pretty easy and inexpensive tog o Flexfuel if you're already doing the kit.

If you are doing straight e85 otherwise you will need a fuel system including injectors.

You're upgrading the fuel system anyway for the TT kit, so it's not much more.

Correct...I thought the original question was around if you were already e85 so it would be as Cy stated if not then you have to do what I did and swap out the fuel system. Sorry for the confusion!

what was difference in tuning with race rom II vs uprev? more power? easy to tune? more user friendly?
