Since it is very hard to source both e85 and ethanol in my area, I appreciate any helpful answers
no. you need a flex tune and an ethanol sensor to do something like that
or have your tuner set up a slider into the Custom Inputs of ecutek and you could set realtime the ethanol percentage in tune based on fuel trims.. but you need to know what you are doing
but do not run e30 with e85 tune it is just not a smart thing, you ll run rich with huge timings
