I'm in a similar boat. I want to try out E85 but I'm actually running Procede v5.
The problem is it's not easy for me to switch map files on the fly, and currently I'm running the 4_23 maps. I could upload the 9_10 maps but can I run the non-e85 maps and try out something like a 20eth/80gas mix for any benefit? Because I know I won't be running e85 very often.... and it will be a pita for me to switch back and forth.
