How does the PCM compute the shift times for shifts?
I set my desired shift times to 0.3s for all gears and logged the shift times. Average shift time was 0.12s for 1-2, 0.22s for 2-3, and 0.77s for 3-4.
How long does it take for the trans to "adapt" to better hit these shift times?
What does it adjust to better hit these shift times?
It's a 4L80E with an HD2 shift kit. I've heard that with a shift kit it's harder for the trans to learn and adapt to the shifts, so many people recommend setting the desired shift times to zero.
