EFI Conversion

it's the hand held. Fitech has stated they didn't think anyone would want the handheld to stay plugged in and visibly mounted, so it's not designed with that in mind. Simply unplug it when you know it will be sitting. It won't lose anything, mine hasn't anyway, and no longer drains the battery
A fast 2.0 is designed to be mounted , and run all time, its the way u keep up w/ the engine .
