I've done a pretty heavy search on here and google but all the answers I found were pretty vague.
Can someone explain the different tables that control the air conditions system in the pcm. Inertia tq, ramp in/out, spark retard, ect. This might be a stupid question but I'm having a hard time understanding what these tables tell the pcm to do.
Is the inertia tq table something that tells the pcm how much tq the a/c clutch will take to engage? So if your rpm drops when engaging, the numbers in the inertia tables should be increased?
I don't understand what ramp in/out is at all.
Why would the pcm want to retard spark advance when the clutch engages? Thanks guys
