No. and if by "hot" you mean 68F, then I guess it depends on how long it takes your intake to reach 68F. That's when a properly functioning IAT sensor tuns it off.
It closes off the pump's internal pressure regulator bleed port. Pump pressure increases and moves the advance piston against its spring. Then the piston rotates the cam ring so the rollers hit the lobes sooner, advancing timing.
None of that can happen until after the engine is running. Base timing is what it is. Most people who have tuned their VE's much have already advanced the timing beyond what makes the 6-8 degree KSB effect even noticeable.

Could be, but did not seem like it to me. I keyed on the part about the KSB having something to do with starting:
There's no "retardation." Like I said, base timing is what it is. And the KSB has nothing to do with starting. It's a post-start pollution control device. That's all I'm saying.

Gotcha, and I was simply trying to say base timing is "retarded" compared to when the KSB is doing it's job, I understand that the KSB only advances, does not retard.
