Thanks Rolls, some good insight to be had from those comparisons.
I was wondering whether you had any more info on the Decel Fuel Shut Off. The Params seem to have slightly different names (coasting fuel shut off, DFSO, fuel shutoff, decel fuel shut-off, CFC, DFS) which makes searching for them hard as there's no common term. Not all are grouped in the Coasting Fuel Shut Off top level either.
In particular do you know anything the references to 'profile correction' ?
The 5.0 seems to re-enable the injectors when coasting at a much higher rpm/speed than the 6 cylinders, I'm looking to correct this to help with city cycle economy.
