What is the name/description of B1940...?
The knock balancing rates are used to balance the sensitivity of individual cylinders which may be more prone to detonation.
These balance rates will be applied on a per cylinder basis to the final knock retard values.
The cylinder designation of A-H is used instead of 1-8 because it cannot be guaranteed each platform using this ECM will conform to a standard wiring pinout.
Essentially, this table will always pull this much timing at said RPM and call it KR. -Nick

It is closing the throttle to make torque.
Please explain then why the delivered torque is plummeting post throttle closing?
Nick
I think because it is trying to make the requested torque by closing the throttle. I should have worded it more specifically. This happens when the requested torque is too high. It also raises IATs.
Interesting, it didn't do it when I commanded 175 so I suppose you might be onto something. Just seems counterproductive.
Have you guys seen throttle openings higher than ~83% or is that typical?
Nick
Nick, are you using the ETCTP PID or SAE.TP? SAE will only show ~83ish, ETCTP should show 100% at WOT (and ~13-16ish at idle).
