Depends on the tuner, not the hardware ;)

Ok, from that I get that it will run it no problem. Got it. Thanks. :)

Yeah you just need to adjust for injector size since you will need about 30% more fuel compared to gasoline.

what AFR should the tuner go for? Same as Gas?

No the stoich for e85 is different, something like 10:1 but its been quite a while since I read up on it. There is a great thread at NASIOC that has all the e85 info you could ask for. Make sure you have a few hours to read though lol.

I left the settings on my wideband alone(gasoline). My LM-1 displays both lambda and AFRs anyways

I just aimed for 12:1 at wot(turbocharged) and 14.6-15 at crusing speed.Just like pump gas but running E85.I also was more aggressive with the timing advance ;) The inner beast in my KA-T came out :eek2:

Yeah those Subaru guys are crazy. I have a friend running a stock WRX Td04 on a 1.8 motor in his '96 outback wagon. He's always running 20lbs with nothing but STi 550's and an AFPR. Stock ECU. How the hell that thing runs on E85 is beyond me. Runs like a champ too.:eek2:

Thanks for that. I've decided to go with the Calum realtime, since it's really not all that more expensive and will give me more tunability.

I've also been running E85 for 6 months or so and I'm loving it. I use a Calum RT and I began looking at lambda instaed of AFR. I have an N60 MAF, 480cc injectors and 4bar fuel pressure, and I just recently installed the turbo. :) I've found that after switching from gas to E85 it's easier to think in terms of lambda than AFR. I shoot for a lamdba of .78 at peak load with 6 to 7 psi boost.
