What kind of energy savings are we looking at?

What is the risk of blowing expensive ECUs?
Here are MetroMPG's results and discussion: Plug-in Blackfly: going alternator optional nets +10% mpg - MetroMPG.com. My own "non-scientific" results seem to be at about a 5% FE difference when I run the alt plugged in, versus running without it. My ECU is fine after months unplugging the alt. My deep-cycle battery is fine too. I've been away at Yosemite for Christmas, and can return to this... thanks for input all.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
