And it does give assist at lower speed in S-mode, I just don't get why it cuts out at higher speeds, why is it speed dependent?

At least, that was my observations on my drive home. Does this look like what you got NASA?
I'm wondering is S-mode might be a better way to pulse given that you can get up to speed faster without battery use. You use more gas during the pulse, but the pulse is shorter, so it may actually use less gas overall. Plus, less regen hit later. More experimentation is needed...

Can someone straighten me out?
