okay i'm trying to fill up my e30 map but i have a half tank of 100 octane in my car still, and there's only 91 at the pump next to e85. Does the current octane in my car matter or should i just calculate like normal as if i didn't have 100 octane in my car? I had like 3 percent of e30 in my car before i just filled up with 100 so i'm assuming my ethanol in my tank at the moment is around 10% or so since i just filled up with 100 and still had e30 in my car. My IATs are running high both on my E30 map and my 100+ octane race map on BM3. Should i just use the normal calculator like i'm normally filling up with 91 and not worry about the octane level in my tank?
