Hey guys!. Finally going to be getting set up with a Flex fuel tune on my car and trying out some e85 for the first time. After talking to Ted today we'll be aiming for e50 so I wanted to ask for you guys that do a similar mix of pump gas & E85 like e40/50. What's the best way to go about getting that specific mixture in my tank on your fill ups since there isn't an E50 only pump? Do you start with a near empty tank and just add half 93 and then a few gallons of E85? This will be my first experience using it and I know several of you guys probably already have a good formula down on how to fill it up with e50 every time.
I do have an Aeroforce gauge with the latest firmware so it should read Ethanol content % but wasn't sure if you have to start and stop the engine several times to see how close you are, etc.
Thanks Fellas!.
