What exactly does the fuel selector do on my EFI ZR, I've heard if you unplug the wires (on 2002 sleds) it will increase fuel by 3% for use with ethanol fuel. I was just wondering if this is true and if it would hurt if I ran in ethanol mode with regular fuel on cold nights for example just to prevent lean conditions.

Not sure about your year, but on my 00 ZL 580 and 00 Pantera 580 you keep it plugged together for regular gas and unplug for oxygenated gas (reformulated). I live in metro Milwaukee area and never use local gas for my sleds.
