1680's installed. Physical install was a cinch, took maybe 20 minutes; the fuel rail is right on top/front on the X so this was completely painless.
Initial settings I had from the guy I got them from didn't work worth a crap, the car idled at 8:1 and sputtered and died. Tried some more settings published on evoM with again, no luck. Then I realized that mrfred had posted some values from a car he had done with a cobb AP.
2.625
1.395
0.825
0.660
0.600
0.555
0.540
he posted E85 scaling: 943
Pump scaling I guessed, ~1.3*943: 1329
Last summer tephra figured out that the original algorithm used to display latencies and I could apply that and use mrfred's values for the cobb car. (link: http://forums.evolutionm.net/evo-x-e...hm-change.html) Still no luck. Car starts and runs good for a few secs above 2000 then as soon as it goes below 1500 it just goes pig pig rich again.
Dropped MinimumIPW down one notch from .040 to .032. flash, start car, bam, fukin starts perfect, revs to 2000-3000 w/o any stumbling or issues, and it idles like a champ. Took the car around the 'block', initial short-term fuel trims look fine so I give it a few brief wot runs, just around 4000, into a little boost to check afrs.
Sad news, wideband in the car is flatlined at 0v again. No knock on the wot runs though, so I guess I'll just be driving around nicely and checking fuel trims until I get a new sensor.
*edit* hit the recalibrate button for the LC-1 and it's come back to life. I'll be testing this setup a bit until the tank is dry....then it's time to sell my soul to the corn gods :P

Oh also, changed the oil today. 3100 miles on this oil, the car didn't burn a drop. I don't say it often enough, but I want to thank MAP for a stout shortblock and DB Performance for a solid head. And while I'm at it, CBRD Speed Factory for such a bad-ass 100% stock-appearing turbo!
We'll see how well it holds boost once we turn it up to ~30 for the e85 tune.

Car was on E and flashing the gas light leaving my garage, drove about 5 miles and then filled up. I fired it up on the pump gas map then after about 20 seconds switched over to the e85 scaling on the alt-map. Drove around after filling up and dialed in injector scaling, settled on ~850 which still seems way low to me. Stopped by jim's house and we went for a rip. I logged and looked, the car is fine in midrange but lean up top, like high 12's. Gah! Also I smell fuel, alcohol fuel...fuel rail is leaking wtf!? Oh, one of the bolts is loose!???!
Yea, minor freak-out moment, but after closer inspection, I realize what I had sorta thought when eyeballing the new injectors: they are taller than stock. The stock spacers were just free to spin and the whole fuel rail was tweaked leaning forward, sitting cockeyed on the injectors. So I snugged it down for the drive home and then checked my garage for just the right spacer. I believe these are old metal center sections out of a 1G shifter base bushing or something, but they fit great! They're metal though, so I hope it doesn't come loose. Also I hope the rail not being cock-eyed helps flow and helps richen things up. I will report back!
Initial impressions--the car freaking rips on e85! I left boost alone for now, ~26psi across the board, and after initial logging, I added 2° of timing, it just hits 15°*at like 7500 or so, still very very mild but the car just feels smooth and powerful and absolutely no knock.

YES! Finally, you have been converted...enjoy the corn The 1680's idle and drive all good? I will for sure need to "borrow" some initial scalings from you
The fun comes a few months from now when you realize that you haven't given a thought to what fuel from where, knock, different "pump gas" tunes and boost settings because that shit just doesn't matter. The car is always set to "kill" for the summer and you never missed an opportunity or worried about pesky things like knock or bad gas. The biggest worry will be "Where is the nearest E85 Station?" which sadly you will memorize about 30 of them before year end and you also start to wonder if the MIL light is broken since it never ever flashes again.
Car felt good, can't wait to see that thing run 30+psi and more timing. 475+hp anyone?

Thanks man! You've been pushing the stuff for years and while I ran I for a while on my 8 it was through winter and always a pita just due to circumstance. I hope it stays convenient for me because as of now it seems way way worth it!

Sorry man, this was literally a fuel stop for me, iv been planning for a while and done it so many times with others, the process was easy. Off work at 6, dinner, fill up, drop off stuff at jim's (I've had a few of his tools since last fall!),around the block and then back home. There will bs plenty of tuning and other fun time, don't worry

No prob. So far it's been dead easy, the X is really really easy to tune and a lot of base values are already out there. I'll certainly be posting mine once I'm done.
