If the EMS has a map select wire or circuit, then yes just as B said you can use a gm sensor to trigger that wire either directly, or via a relay circuit. Typically controlled by just a switch to ground. That ethanol sensor is just an overly complicated switch in the end.

I don’t know of an aftermarket EMS that doesn’t have that map select wire/circuit these days. :ponderMotec, AEM, Hydra, OBR, Autronic, 034, MS, etc, etc all have it. I’m sure alot of those Honda PnP’s/etc do too
