The Flashpro help file describes knock control as the way the ECU has determined the fuel octane you use.
0% Knock control means you're using 100 octane
100% Knock control means you're using 90 octane
In a perfect world, people running 93 octane will see 70% for this value.

Normally aspiriated
If the car is tuned on a dyno, and the main ignition timing tables are set to the proper values, should the knock control value be 0% all the time, or does the ECU still try to compensate?

Another question... I know the knock retard backs off timing, and you can actually feel the engine losing increments of power as it does this, but what does the knock control do?

Edit - Is there any difference in ignition timing or fuel values from the ECU when the k.control is 0% compared to k.control at 70%?

The knock tables were created using RON octane ratings, not pump octane numbers.

If the ignition tables were set all below the knock threshold then the knock control should set low. In practice, this is very difficult to do on pump fuel.

Knock control will change the ignition timing, but not fuel.

Hondata unfortunately in the FlashPro of still difficult to determine where the detonation.
And it can be seen in the picture below.


In K-pro as in Aem tune detonation has been recognize much easier
than in the FlashPro .





I only see the two options:
1 -Add knock level voltage to sensors
2 -
