GD we got some smart folks in this bunch.
Serious question: are there any other online communities that are this technical and knowledgeable about this kinds of ****? Seems like other forums I go to, changing an intake tube or swapping your own trans fluid is a really big deal. But I'm not real deep into like national subaru or anything, I think that's smart folks too.

In other news, I siphoned my tank, dumped 4 gallons of e85 in, bumped req fuel by 40% and started the car... fired right up... WBO2 warmed up and showed ~.0.65 lambda (like 10:1 on the gas scale) loool.
Shut it down, set req fuel back, fired it up, let it idle for a bit, it slowly leaned out to 15-16:1 on the gas scale, so I flipped my "rich switch" (flips to a fuel table 20% richer across the board for hot restarts) and waited until that was at 15.5:1 on the gas scale, then shut it down, flipped the switch back, bumped req fuel again, and fired it up again.
Got it idling at 15:1 on the gas scale with req fuel 40% above "normal" so I think that means it's all e85 in there now.
Then it started POURING rain, so I went inside.

So the MS3x potato schematics are useless but I've been told that it is a direct connection to the MS3 input pin. Which according to this already has a 10k pullup. I need to double check on the pull-up but otherwise the filter circuit should still be added.

Up and running and driving around on corn.
Ohhh the smell!
Still running my 460cc injectors for now, just tuning my NA fuel cells and low boost low RPM (spools quicker!) while monitoring my duty cycle (keeping it below 50% because I'm a ***** bitch).
775ccs go in today after work, and then it's time for real-tuning!
Also, with my super open exhaust, and the increased exhaust flow, my car is louder now. Like, it sounds like previous WOT at about 50% throttle. I'm curious if I'll be under my autox noise limit now...

Been a few days on e85 now. Fuel map is getting close to dialed in, going to start tuning timing soon.
I went 2 steps colder on plugs when I went turbo with gas. Should I go back to stock heat plugs? Something different? Leave them colder?
Ev14 4 lyf btw

Interesting behavior since going to e85: car backfires like crazy when I fire it up. I tried dropping cranking pulse, and it helped a bit, but now the car seems like it's barely getting enough gas to start.
If I just crank the key, the car goes BOOM, i'm talking like duck-and-cover-oh-****-who's-got-the-gun.
If I turn the key, let it prime, and then wait about 5 seconds before firing the car up, there's no bang.
If I wait about 2 seconds, there's a much smaller bang.
Seems to me I'm possibly pumping too much gas on prime.. I tried lowering priming pulse and it seems to have helped a bit more, but I think I need to drop it even further.
Is this normal?
Is it okay to make my priming pulse practically zero, and then just give the car it needs during cranking?
Is there some other fix?

its not normal. IMO, the trick to proper startup is that ALL of the affected/affecting areas need to be just right.
that means: VE map, Spark map, prime, crank, ase, wue, etc.
I struggled with this for EVERRRR until I figured this out. I think I messed with cranking fuel for like a week or two on the previous car

Thanks Vlad, that all makes sense. I felt similarly when I finally got my car up and running on ms2 (took nearly 4 hours of tinkering). Then I got my ms3 basic from rev and the car just... Started. Such a love hate relationship with that.

I still remember when I got the car running and was out tuning and stopped by a Miata buddy's house to show it off and he was like "it's idling a little high, isn't it?" and I nearly throat chopped him..
