I got this issue were after 100% throttle to 14% throttle. The RPM will still increase 200-400RPM before it actually goes down. I get knock when this happens. any cure to stop the knock during this throttle hang. I dont mind the hang but the knocks suck.

 

Hmmm ... I never got knock with this issue ...

But, I just posted a new map you could try ... https://www.evolutionm.net/forums/sh...226466&page=21

 

ya I had already read through that whole thread by search. But it seems all the threads just talk about the hang and not knock.
my timing is not jumping around and is conservative. my a/f is 11.3 so definetly not to lean nor rich. Really weird how the hang causes a knock?
