Thanks guys. This is at the end of the list due to potential of drivablility issues on a dd. Its a long list also, but I will post progress.

Exactly. The concept is from motorcycles, where engine braking during shifts is not desired. Historically this has been done through slipper and sintered clutches. Now, the ECU's are being programed to stay slightly open to reduce engine braking. Hopefully the software and controls will bleed over, and we can extend it to full WOT.

This should improve narrow window of speed P&G in tighter traffic, and remain legal (since EOC is not in some areas).
