Whathuh? Details on transmission Cy!!!

Why not 2 tunes?

Or do I just not understand E85?

That can be done, but you basically have to run the tank dry and then pump in 93/91 and change tunes. If you have half a tank of e85 and then throw in 93/91 you will need to have a tune for that blend also. Other option is to siphon out any left over fuel when he is in the dead zone for e85.

Ya I can always have different tunes for different fuels but it's unrealistic to dry out my fuel system and switch fuels while driving from cali to tx. Carrying extra fuel is the most realistic option.

Carrying extra fuel would probably be wise, plus this allows for errors on mapping if a station drops e85 all of a sudden.

Ohhhhhhh, ok.

What if you ran a tune for 91-93 octane? What would happen if the gas is even 50% E85, you should be ok, no? BUT when you go back to E85 you'd have to run it dry

And E85 isn't consistent to begin with, so do you tune rich every time because there is no flex fuel kit yet?

I think it's a very bad idea to run a certain fuel with another fuel's tune, even mixed. Normally they drain the fuel system before they put in a different fuel for a different tune. You don't want your car to "run" dry. I've done that on the track due to the stupid "dots" fuel gauge.

E85 is a real simple decision guys.

If E85 is available 24 hours a day within a 20-30 minute drive for you, then there is nothing left to think about.

Once you make that switch, you will be like everyone else that ever did... and anytime you see someone question it, or have trouble making up their mind, you will want to shake them and yell

2-3 min drive for me, but that station closes at 8pm and i am usually at work later than that. So if I need to fill up after 8pm, I have to drive about 25 min away.

GOD FORBID i have to drive a lousy 600hp car for 25 minutes. ruins muh day.

Meh the winter batch within my area has been 78-82, but at work it's almost always 83! At work they run out like all the time lol. Service vehicles use so much.

Let me step away from what is professional to recommend, and insert a little bit of "what you can get away with".

I have run my tank nearly empty with no E85 station within range. Added a couple gallons of 93 octane, and (carefully) went on my marry way... running my one and only tune, my e85 tune.

The side effects... the car will run too rich. However, closed loop feedback from the O2 sensors picked up and fixed this within a few seconds, and the car was perfectly driveable and ran clean A/Fs for part throttle.

This would *NOT* be acceptable for aggressive driving or going into boost at all. The ignition timing on higher load would be too aggressive for 93 and could cause immediate engine damage.

The point I am making is that if you find yourself in a SOL situation, the car WILL run and DRIVE without causing immediate damage or long term effects if you are VERY careful. But you get into the throttle too much and you can kiss your motor goodbye.

You will want to run the tank practically dry and refilling fresh with E85 before driving it hard again to make sure you pretty much got rid of the piss water. But you are not stranded on the side of the road if you absolutely cannot get to E85.

Yes you need to empty it out as much as possible. Honestly just get like 10gal or more in tanks. I carried a 10 with me and hardly used it. Trip was 350 miles with about 3 hours of traffic. God that sucked. But once I got out if traffic, you bet your ***. I was having fun on my way home, still managed a decent mpg.

Or you can drive home on a gas/low boost, then COMPLETELY EMPTY YOUR FUEL SYSTEM (not just tank) and swap over, but where is the fun in that?

Exactly. I will not risk damage my motor so I will be well prepared for this trip.

Cy,

If we did the changeover, we will completely drain your tank of all 93 octane. To properly tune the car for E85, there needs to be nothing else contaminating it! Unfortunately the flex fuel sensor capability is not available for the 370Z...Only if the Z had the on board technology as the GTR. Only if...
