The knock sensor does not currently interact with the fueling, but the EGT Safety feature can add additional fuel if the EGT temperatures rise too much.
Is it possible that knock control will also use "over fueling" to get control of knock?
Current knock code only adjusts spark timing.
Is a wide band knock sensor capable to detect knock in all rpm ranges?
That depends on whether the background noise gets to be too loud and interferes too much.
And what about knock contol on boost?
Is no different than knock control at lower kPa levels.

Good Job cortina I see you are using the ms to do the hard work. Good idea. Some day we will get to perform a
side by side comparison. The performance should be similar given we are using the same chip.

:shock:
