Now that I've put my fuel injector kill relay on a toggle switch, installed MIMA for manual control of the electric motor, and have a strong battery in place, I've got EV mode.

It works! I can go places using zero gasoline.

It's not great. Range is predictably short, acceleration requires everyone on the road to be patient, and charging takes so long that I can pretty much only do it once a day.

I mostly used it for cruising today, due to traffic. It looks like I can cruise at 40mph for about two miles, going from a topped off battery pack to 3/20ths indicated SoC. My best guess is it'll take 0.6KWh (8hrs) to recharge.

I usually get mid 60's mpg on this 5.5mi route with 14 stops, and today I got 93.2mpg + 109Wh/mi, or 57.0mpge. I saved ~0.025gal of gas today. Do that 200 times a year, and I'll save five gallons at the expense of $14 of electricity.

I expect I can displace more gasoline consumption and use my charge much more efficiently by using it to accelerate instead of cruise. Time will tell. Still, I had fun today.
