[QUOTE="lowranger96, post: 14676352, member: 80449"] for e85 tuning: first make sure fueling is all in terms of lambda, there should be a fuel afr stoich scalar that is currently set to 14.08-14.7 something like that, you'll want to change this to the stoich ratio for e85 which is 9.7. then you'll want to increase your cranking fuel pw by 25% (multiply cells for pw by 1.25) i would do some datalogging to make sure that everything is working well (your wideband will still read out gasoline numbers so if it was at 11.5 wot afr then it will still read 11.5 now.. this is because the wideband reads the lambda and converts it into gasoline numbers.. so unless you have a wideband that you can change to e85 numbers then it'll read the same as what gasoline read. keeping in it terms of gasoline afr often makes it easier imo) after that you can add a few degrees of timing to enjoy all the perks of that added octane ps: watch your injector duty cycle with those 80s at 700whp on e85, you might run out of injector [/QUOTE]
