I tried this for a while and while it works, it doesn't work all that well.
However, the IMA system also disables auto-stop under two other conditions: when outside air is below 40F, and when the climate control is set to "auto". I'm thinking I might feed the computer a 50% battery signal all the time and disable auto-stop by either telling the computer it's cold outside, or by figuring out what signal the climate control sends to keep auto-stop off. I suspect it's actually just going to require cutting a wire.

Can't you use the arduino to change the MPH cutoff for Autostop to something like -1 MPH, so Autostop never occurs? If I remember correctly you said it was possible to change the "SOC" to where you could get Autostop whenever you put it into neutral, maybe something using that?
Also, where is the ambient temperature sensor located on the Insight? I want to move mine so Autostop isn't disabled under 32F..
