FICM/ECM Rollback Passes Final Test (Cold Start)

[MJ365]

Went out to start my 04 the other day when it was -5 F all night and only 0 when I fired up my truck to see how it would start without any inductive heating and not being plugged in just to make sure it would. To my surprise it starts better now with no IH than with the old death IH strategy I had previously. I let it warm up until the high idle kicked in (3 min) and down the road I went nice and easy as always until it warmed up. Gone is the jumpy clanking idle, the big flat spot off idle, the shifting is way nicer, and its alot quieter when cold. Before it sounded like all the rod bearings were gone when it was cold. Another thing good is it's still getting 16+ mpg in the cold when it usually was down to about 14 by now with mixed driving.
