The car doesn't come into boost any easier on E85, just takes a lot more fuel. Is the increase in MPG hand calculated?

My point was in boost it does consume a ton more fuel than pump. I don't know about you, but even small amounts of throttle input to do light acceleration would put my turbo cars into at least some level of boost, and as such into richer AFR targets than stoic at cruising. I can give you much crazier examples -- I have a guy with a high c/r N/A 2.5L motor build in a Honda that gets crappy gas mileage on pump, but on E85 he does 40-50mpg -- the car will go from Ventura to Sacramento (California) on 2/3 - 3/4 tank of gas (it's a Civic, so roughly 9-10 gallons). My turbo S2000 gets 19-21mpg on the freeway on E85 with a built motor. Factory they're rated 22mpg. These are definitely the exception and not the rule... as usually I do see a 20-30% hit to economy on E85, but I can't say it's "always" after doing it long enough on a bunch of different platforms. |
which injectors do you recommend?
do i need to switch from uprev to ecutek for the tune or is staying with uprev fine? i know ecutek offers launch and few more things, but i don't need that |

Thanks for posting Vit. Also saw this on your blog. Wish you were down here in AZ so you could mess with my tune! You've tuned like 4 of my friends k20s hah!

I should be visiting Phoenix sometime soon, Andrew should be wrapping up his turbo K20 MR2 sometime soon -- we'll see if we can get 900whp+ out of it this go round! |

With the VVEL/VTC system on this motor, do yourself a favor and find a competent tuner with a reliable dyno. I've seen minor 2-3* changes to VVEL net 4-5tq through parts of the curve, or the opposite -- cause huge 40tq dips in the curve. The goal is to fatten the area under the curve, and you're going to have a hard time trying to get 4tq here and there (and the cumulative effect is nice).[/QUOTE]
Yea finding a local tuner is a 0 to NO shoot for me Mass has NO ONE. My dyno and TW curve is flat :) |

My point was I can post overlays of 5 pulls for you and show you how little changes in the VVEL made minute gains between pulls but the cumulative effect was greater than the starting point -- you don't have that kind of precision and repeatable doing a street tune. In an case, I'm not going to argue the merits of street tune (etune) vs dyno tune. They both have their niche. |

We made 10 pulls total, 5 on each software |

This isn't a result of being boosted. If you take a TT 370z and take the MPG readings, and THEN convert to E85 (just as Blake did), your MPG's will indeed decrease. Will E85 make more power? YES, why???? Ignition point = It means you can run a few degrees more timing (all in the tune) E85 ignights at 365 degrees 93 Octane Ignites at 280 degrees |

In fact simply stating the fuel allows you to possibly run more timing to make more power is nothing more than an assumption. In many cases I've had N/A motors that want zero timing map changes on the fuel over the pump gas map. |
