Eric, I've got a relay that I installed next to my ECU that cuts all three fuel injectors, reducing fuel consumption to zero. Mine's wired to a momentary switch. Wire yours to a toggle switch and combine with MIMA, and you have EV mode. However, you can't stop the crankshaft from rotating, so you wouldn't save any engine friction. It would still be fun to take short trips on zero gas.
One thing I've wondered about lately: can the Insight's IMA motor and inverter stay cool when you're doing full assist continuously? Well, I guess you or Mr. Perkins would be the ones in the know. Had any issues at all with it?
I believe that by energizing fuse #24, you can power up the HV contactor, MCM, and BCM with the key in the "off" position. If you add that to your plug-in routine, you could add another 6.5Ah from the traction battery. You could also power up DC/DC converter pin 1 to charge your 12V battery for another 3Ah-equivalent.
Hi, Arctic! I envy your patience and hypermiling skill. Do you P&G around town? With a few mods, I hope you can get up to 120mpg.
