Got my firmware updated today on my 2006 HCHII, in turns out that the free thing they were doing on my car was a safety recall to do with wiring on the DC to DC converter, the firmware update was not free and I paid $63 for it.

The car did seem to pull away from a stop smoother and a little more urgently, but I only drove it less than a mile to work so I will have to drive it more to really see if its made a difference.

As an update, the harsh engagement is absolutely gone. It drives *way* better now, especially in stop and go traffic.
