As mentioned by Insight owner and hypermiler Randall Burkhalter in the first Hybrid Fest video posted, the MIMA system is an electronic retrofit which allows the driver to manually control the Integrated Motor Assist in the Honda Insight. At Hybrid Fest 2007, I got to meet and interview Mike Dabrowski, who invented the system and is building and selling them to Insight owners.
The simplicity and the results of the system are remarkable, however, Mike is running out of the control boards that make it possible. He's working for cheap because he really wants to do the green thing (check out his personal Insight) and do what he can for the environment, but if people aren't going to order them any longer, her can't invest the money into having more boards made. So if you own an Insight and want to maximize its efficiency, call up this self-proclaimed "mad scientist" now, and thank me later.
