car started up pretty good as it was. but was curious if I could improve it a little.

looking around the DA3 code and found that the Crank Fuel Delivery Delay vs MAT was mostly 0 to 1 reference pulses, compared to 8D which was a lot of 4s, 6s, and even 8s; and seemingly not even in any logcial order. Not sure why GM put such a delay into the crank fuel delivery, but I ended up putitng in the DA3 values. Starts up quite a bit snappier now.... nice improvement.

for anyone curious, DA3 is 0 from -40 to 44, and then 1 from 56 to 152.

I personally would leave the crank fuel delay. I feel a couple of revolutions of the starter before the engine actually fires helps give the oiling system a head start which equals less wear and tear over time.

it still cranks over a few times, so it should be fine.
