Here is a close up picture of that curve. I didn't realize it was
that bad.
I tried some engine off coasting and bump starting today. I liked it, and because I have the power steering disabled, the only difference is that the power brakes run out after a few presses. I didn't like having to turn the key, though, so I finally made a kill switch (using info from
here). I tried it out, it works, but my ultragauge turns off, too. Not too big of a deal for me, I mainly use it to see how different things affect mileage, not what the exact numbers are. I mounted it to the side of the shifter with velcro in case I have to move it for some reason. I haven't driven with it there, yet, but it seems like it work well.
(yes, my car is messy)
