E85 - First timer, observations on mpg.
Travman is getting hooked up with a set of FIC 1050's so we shall see if the problem persists after the injector swap. He is running PTE/FIC 850's right now. I'm on the same "style" 1000's in my DSM and I think I recall having part throttle popping in the terms of "yo dude, you have fire coming out the side of you car" due to my side exit exhaust. I'm sure its just a tuning thing and maybe the different style FIC's don't exhibit the same problem. We shall see.
If the problem persist on the new FIC 1050's well just do the gasolene+match+torch trick to the car and claim insurance. Well maybe travis won't do it but I'll slam a 12 pack and do it when he's not looking.

^ Yeah I am really whining about it......
I get about 17mpg normal driving city/hwy . Crazy driving I get about 14mpg.
Iam running Pte 1000cc injectors, My car does not backfire.
I was getting about 21-20 mpg normal driving city/hwy on 91 oct.

- I get almost the exact same mileage in town and on the highway too.
- Every once in a while I get a "backfire" (they're not really backfires) if I touch the throttle during decel. Otherwise nothing. If you let off on the throttle from cruise, your injectors should be shutting off, so there should be no fuel to ignite in the exhaust. If you release the throttle from open loop, the injectors will continue to operate.

I think a liberal amount of sub 100% load partial throttle timing is what is needed to extend the gas mileage. That and adding in some EGR to reduce pumping losses should help out quite a bit while cruising. I do not get the part throttle pop, it might have something to do with the generous timing that I run. If I do get the pop, I just don't notice it. The car is very strong part throttling around town, very pleased.

Update:
1050's went in this weekend (much easier w/ 2 hands and a garage thanks danl), used mrfreds latencies and scalings - everything is pretty much perfect (Thank you Mrfred). Those injectors are really nice, car runs extremely well now - that pop I was getting in between shifts at part throttle is now gone.
Re-tuned the fuel map and I'm running 11.8's from like 4000 rpms on - car loves it. I did a 1-4 gear pull after I had it dialed in the best I was going to get it that night and it took me 11.7 sec. to get from 11 mph to 108 mph. This included shifting and the slight delay waiting for the car to spool in 1st gear (didn't launch it). I got the info from my log seconds and took from where it went 100% tps in 1st to where i lifted in 4th at 7200 rpms. I had 1 count of knock in 1st gear and the rest was flat lined...Best part was smelling clutch at the top of 4th gear (held 23 psi all the way in 4th) - wonder how much longer the stocker will last? I am very much looking forward to gear based boost control
I am overall extremely pleased with the car.....I honestly don't think I can ever go back to 93 octane.

Yeah, mrfreds latencies are dead nuts on for 1050's and they also work for 1150's. The only other major adjustment is adding nearly 3x more fuel for cold cranking around the freezing mark.
The performance is seamless. I let an extremely picky car guy drive my evo on E85. He's the kind of person who can find faults in driveability of a stock evo, let alone one that has the power to spin third gear on a damp road. His impressions were how darn smooth things were and how much power their was. I think your doing something right when you ask the driver "how high were you revving it and how much boost was on the gauge". The driver replies "I don't know, I was glued to the road". This driver was only taking it to 6000rpm's, had no clue what speed he got it to (he got it to 120mph), and really didn't know what the boost was.
Trav, how is your gas mileage working out? I got 18mpg last tank really railing it hard.

Cold start this morning was one crank - it was about 35 degrees out, very nice. The warm start needs a little work, when it starts it gets a little blubbery and the rpms jump to like 1200 then fall to 500 then go up to my normal idle setting. I will get that squared away in time....
Yeah the car is ridiculously smooth......the 1050/1150 are a great injector.
Nice, I have the FIC 1050's too, and I don't get any popping or backfiring on decel in mine.
E85 is fun, and I think you are learning the same things about it I learned awhile ago with the mileage; There is no point in really "trying to conserve" it to get more miles out of a tank, so you just lay into it all the damn time like I do.
E85 has really made my car more forgiving, and much more fun to play with. I really feel as though I don't have to monitor the knock with a hawks eye nearly as much as I did before with regular gas.
Just make sure you start to tune the new maps that were found to help in start-up. I used Bryan's (razorlab) advice and added a ton more fuel to aid in start-up, and it helped tremendously.
And you are correct, the FIC 1050's seem to be a fantastic injector.

On 93 it didn't matter what I did my car always was picky with knock and it was quite annoying. E85 has changed that completely - knock is almost non-existent and I find myself finally not having to care. I run like 7 deg. at peak and 17 deg by 7500 rpms, keeping it nice and conservative w/ 23/24 psi tapering to 21.5 at 7500.
Yeah I have been tweaking on those new maps since they were found, helped out a lot with cold starting and stuff.
