E85 Experience
Thought I would post this just to spread the knowledge.
Have been running E85 for about a year now and have learned several things from it.
E85 is different than gas in respect to AFR's. You can run way leaner with E85 than you would with gas.
With gas, I would try to keep in the 11's as far as AFR's go. I assumed E85 would be the same. Found out yesterday it isn't. I leaned my AFR's down to 12.3:1 and my car instantly became a different car. Before, I was running in the mid 11's and it seemed pretty fast, but when I lowered it, now my tires just spin in 2nd and 3rd when I punch it.
I found out that running rich with E85 is actually worse than running lean.
A few months ago I actually had E85 and meth injection running at the same time.
One day I was out playing around and punched it. Right when my meth injection came on, I heard a POP! I took it home and found a cracked rear iron.
The result of too much liquid in the chamber and a misfire.
E85 is very hard to detonate and is very forgiving. Every rotary should run it. It's a no-brainer.
I dynoed my car at 545 RWHP last Fall. I would estimate it's in the low 600's now just because I leaned it out.
Now all I need is some rubber behind me so I can hook up!

E85 is ok, but with less than 1 gas station having it in every surrounding city and you use alot more of it than 93 kinda sucks..so i thikaround here in my area it equals out. You can drive 20miles to fill up, 20miles back home. you already used a few gallons just going to the gas station
. Also going on road trips you have to map out gas station routes. Other than that...
very nice fuel.

If everybody that had owned a rotary, converted to E85, there would be a lot more rotarys running around to this day.

E85 is a good fuel. Just don't let it sit in the tank for extended periods of time or it will turn to a jelly like residue in your fuel filter and clogg the fuel system and cause the car to lean out under boost. This is what happened to mms this week. E85 is very forgiving..............

I have had E-85 in the tank for three years now and with three winters of storage (4-6) months I have never seen any adverse effects. No sludge, no tank dissolving corrosion.

I won't let go
I think I did go small on my injector setup. I'm running 6xID1000s (with an FJO box) and at 20PSI on a TO4Z, I'm near out of injector. I'm also running 2x044s.
What are you running for base pressure? How much boost are you running and what are your duty cycles up top?
I'm probably going to swap to ID2000s for at least one set of secondaries. Though you say the 2000s are OK, I'd think you'd have better fine tuning in cruisabillity by maintaining the 1000s in the primary spot.
I'm about 480whp on my setup. I'm at around 11 AFRs as well.
BTW, I'm on a PFC.
EDIT:
NM...I see your sig.

Not a pain at all. They're just wired in parallel so I just change the setting as such in the PFC.
IIRC, I am running neg lag, though I don't recall what exactly. They respond to changes pretty well so I'm not too concerned about it so much. It does idle really well...on a half bridge, I've got it to about 1300-1400 at about 12 AFRs.
As of now, I am strictly E85. It's relatively easy to find in my area, however, as my car and I are seperated for the forseeable future, any changes to play around with settings are going to be far and few between.
I'd definitely recommend a gas map. I think I can squeeze 14MPG on the highway with E85. And that's tuned to about 14-15 AFRs in cruise at 80.

Railgun, you're running an FJO box????
If it's an injector driver box you are referring to, please remove it!! It is designed to convert to peak/hold style drivers for low impedance injectors. ID injectors are high impedance saturated injectors, so you should NOT be running this. The PFC will drive the parallel ID1000 secondaries fine without resistors or peak/hold box.
