That looks great!! My goodness, I haven't looked at the code in quite a while. Could you type "config" and post that here?

Do you have max-regen-position < min-regen-position < min-throttle-position < max-throttle-position?

Here's a sample that would be good if your range of throttle was
0 throttle == 315
max throttle == 800

Try this:
max-regen-position 320
min-regen-position 400
min-throttle-position 450
max-throttle-position 800
