E38 Crank Fuel to Run Fuel Transition

[Wazzup13]

Anybody know what parameter controls the crank fuel to run fuel transition? I get a big drop in injector pulsewidth in between the initial crank pulsewidth and the run fuel. This causes a hitch in the engine run-up after crank. I've tried about every parameter with no luck. I can adjust the base crank fuel and the run fuel but there is a dip between that I don't seem to have access too.
Crank Fuel Blend Factor only effects the magnitude of the run fuel vs. crank but not the gap between.
See attached file for a picture of what I'm talking about.
Vehicle is a 2009 2500 Van with a 6.0L
Thanks for any help.

Have a look at B0181 and B 0182. These should help.
