It's funny this topic should come up today:
Actually Dave, you should get your facts straight... just kidding! I'm just
psyched because brady and I just got back from our maiden spin on the new
e85 tune, how's that for catching up with my dev goals Dave? all I have to
say is SWEEEEEEEEEEEEEEEET!!!!!!!!!
But guys/gals it is so cool!! The first thing we noticed is that the exhaust
smelled "funny" in that it really does smell a whole lot cleaner than the
gasoline, although you can still detect the 15% by nose. We rushed over to
the local smog station to get emissions numbers from the rolling road dyno
test, but junior had already gone home(who works to only 4pm!? LAME)
Anyhow, the seat of the pants dyno is already picking up on some new
power... and this is just my baseline. I'm going to setup some dyno time in
the next week or two and bring it down to start work on the power tune. Much
more so than for gasline, having multiple tunes for the e85 will yield some
nice benefits, the econ tune will run the setup as lean as safe to make up
for the additional fuel volume that e85 needs to make the same power(I'm
hoping to lose only 10-15% in MPG for the econ tune vs the 25-30% normally
associated with e85), and the power tune will take full advantage of the
equivalent race-gas-like 105-110 octane of e85 + it's charge cooling
effects. I was looking at injector pulswidths, and it doesn't look quite as
bad as I thought in terms of the amount of extra fuel so things are on
track.. but I'll collect some good mileage/consumption numbers as we move
along... the good news is that the stock zetec injectors can support at
least the baseline tune no problem... we'll see once I start to really give
it some fuel and add loads of spark advance on the dyno for the power tune.
Jason in Colorado is going to be really happy, as once I email him this beta
tune he can reflash his zetec and start running the 99 cent per gallon e85
they have in town in Fort Collins... SWEET!!! Did I say sweet already? So
we should have some dumb low emissions numbers to share with everyone
tomorrow.. likely the lowest a vanagon has ever produced while
running/driving. But the best part is(and this will take some more testing
to confirm) customers will simply need to download the new tune from the
support and dev website and BOOM, they can run e85.
Ecstatically yours,
Jim Akiba

Bostig is in progress of setting up a E85 tune. They should have dyno
results in the next coupe of months. My plan is to run a 2 boost levels
turbo Zetec with one level for max efficency and the next for max power and
E85. Both projects are running paralel to each other at Bostig, which is in
the process of adding additional man power to help with there conversion
demands and free up some time for Jim and Brady for R&D.
Cheers,
Dave Syncro Westy Zetec soon to be Turbo/E85

I haven't seen this question asked so i thought just for the
discussion, what would it take to convert our stock engines to run on
e85. Also are any of the available engine conversions compatible to
running on e85. The bostig zetec? or a subie? Just curious e85 is a
buck cheaper at my gas station so i ponder the question.
