Very risky! 30/70 mix is easy...run tank down to about 1/8th tank...add 10 gals of 93 and 4 gals of E85.

The new alpha firmware on map5 is the E85 map of choice at the moment but its still in testing.. Map 7 is for the brave

Negatory. None around here, just straight 93 octane in my tank.

I've been running 70/30 - 93/E85 for almost a month now on the old map 5 and I thought it was great and the car ran great... but then I uploaded the new beta 5-1 firmware on Monday, and WOW does it really run great now! The extra power is noticeable, but man it is sooo smooth now! I don't see how it could get much better, but Terry seems to find a way to make it better every time I've tried new firmware.. So now I'm uploading the revised beta 5-6 firmware as I type, so we'll so how that goes! Then on my next tank of gas I'm going for 55/45 - 93/E85

You sure can, but if your on the older firmware you shouldn't run more then 30% E85 IMO. My fuel trims were close to maxed out when I was running 70/30 on map 3 with my meth additive set to 60, but thats what got my 11.98 @ 114.08 at the dragstrip

But with the newest 5-6 firmware, Terry has said that ALL the maps have the auto tune function now, and the only thing that makes map 5 different is that it targets boost. So I can't wait to try map 3 again once I get my meth tank filled up again

the car feels smoother on acceleration to the point where the speed is deceptive with a 93/E85 50/50 blend. My Wastegate cycle duties max out, so I my current 18 ohm board isn't taking full advantage of the mix.

This is my feeling with the older 0325 firmware. Can't wait to try this on the new firmware.

also running map 5 on the 5/1 firmware, on a 70/30 mix with no meth... as many have stated already, it pulls strong. i updated to the 5/6 firmware last night, but it was too late to run logs. will have to wait til tonight.

i am calling my local dyno shop today to try to get in this weekend... i need to know! LOL

below 2500 vibration is Knock!!! be carefull

**UPDATE**

just went for a 30-35min hard drive... car runs perfect.. no vibration.. just smooth pulling .. i think the map needed a few more 3rd gear pulls. the other thing i noticed (during hard driving) i usually see oil temps in the 240-250 range.. today i couldnt get it to go more than 220? not that im complaining could this just be a coincidence or is there something to do with the cooling effect of the E85 resulting in cooler oil temps? i could just be overthinking this whole thing too
