First test (RTB found this one): deceleration column has some values different from zero.
A lot of people complain about the idle staying high if revved in high range and trans in neutral or park once the engine is at operating temp. This coincides with the map differences in the 0% throttle column.
We were hoping for improved engine braking by setting all bins to 0. Turns out the revs drop to idle instead of improving engine braking, see youtube link below.
