"Post Start Fuel Adjustment"

What is the extra fuel added - % or INJ msecs - at the setting:

Post Start Fuel Adjustment = 0% ... at 31 Celsius (for example)?

And is it entirely independant of the cranking pulse within the first few secs after firing or is there a phased cut-over?

Is it compensated for by
-injector size
-fuel trim/pressure

Can you share what is the programmed

Post "Start Fuel Adjustment" INJ correction % at each ECT band

for step 1, 2, 3?

Is it approx 22% fuel compensation at 31 Celsius for step 1?
