yeah I've heard united often runs up around the 90% too

race car smell is always good especially when mixed with bridgestone's finest

yep, it certainly does!

Corn is amazing fuel, youll be suprised how much you can lean on it. Im making well over 400rwkw with corn and a gt35/40 on a v6 ecotech

Wow thats awesome power! One thing that is good in a way is not being as fuel limited for advance, but also means the knock sensor is next to useless now. No pinging just hammering bearings instead! Need to figure out a cheap in cyl pressure measuring system ... mmm more sensors

the solution to your advance issue is increase the boost, that will limit your advance a bit if it doesn't then the boost isn't high enough hehe

Thats why you tune to the minimum advance value to produce max torque. The torque plateau and then drops once you go too far. You want timing to be the smallest when that plateau starts.

you'll never had excessive pressures then.

Yeah I know, tune the same way as on petrol. I wasnt saying tune via the knock sensor! Just that you cannot rely on the knock sensor for feedback anymore to retard advance like you do on petrol.

Its a very different fuel, burns faster so less advance is needed where on petrol it was not fuel knock limited, but where it was fuel limited can get more advance in.

haha yeah thats the way!!

Took a reading of some United E85 straight from the jerry. Not sure if it will be 100% accurate as there is no flow, just fuel sitting in the sensor ...

Maybe you can calibrate it with lab grade anhydrous in 100%?
