So I'm trying some Hyper-Economic driving in my 1995 E320T now that its beginning to cool down.

There is a three mile stretch between my house and work where I can put it in neutral and coast. Because the transmission doesn't like being put into drive while rolling in neutral, I'm trying to work out how much to push the gas pedal to turn off the engine braking without adding more fuel.

I feel about an inch of no tension motion in the fuel pedal before it starts adding fuel. The Question is, how far do I need to push the pedal in to cancel the engine braking.

This morning I'm going to leave it in drive during the 3 mile stretch and see if I coast as far as I do in Neutral with the fuel pedal pushed just to the end of the tension free zone.

Any info regarding manipulation of the engine braking would be extremely helpful
