Idle Tuning - Idle Advance

alright so let's see that Idle Advance channel in action

note the numbers are a little bit off, but that's because I got rid of the decimal point and also there is a bit of a lag behind what the actual timing is and what HP Tuners reported, but it's close enough

again, the most important take away is that this Idle Advance parameter is the difference between the actual timing (Timing Advance) and what the timing should be (Base Advance) it is the PCM's attempt to make things right (how and why, coming up next)
