Advice with E-85 and dsmlink

[Calan]

yea I'm running version 2.5, I'm just making sure so when I start running E85 I can get the correct AFRatio est. So is it 0.796 if I'm always running E85?

.796 is the SG of pure ethanol (E100). The SG of E85 is somewhere around .785, if it's truly E85. And it varies a lot depending on the gas it's mixed with and other additives.

You may want to check out this thread over on the link forums. I found some interesting stuff when I tested a bunch of different fuels.

Thanks, I'm in MN so avalibility shouldn't be a problem for ethanol. And during the summer it's 85% ethanol and winter is 70% but since this is a summer car that doesnt matter. As long as .785 is ball park of what SG of E85 is I should be fine. The guys test were with 91octane and gas can be mixed with plenty of different blends/%'s of ethanol.
