Hi!
I am currently using cobb stg 2 with AMS intake.
(Cobb AP firmware is v1.6.5.0-2223)

I would like to check knocking of my Evo X so I tried to log some data but somehow I couldn't find 'Knock Retard' on any Cobb AP menu like Set Live Data List and Set Data Log List . There is 'Knock Sum' instead of 'Knock Retard'.
I actually repeated to look for the 'Knock Retard after I reset ECU. However, No luck..

Do you guys have any idea??

Knock retard = 1/3 Knock count, ie 3 knocks = 1 retard :-)

So Knock sum = Knock count?
What % of Learned Knock is good ?

xhomm02

1) yes
2) 0

Not entirely true. Most cars you will see a little knock off idle from a stop so 0 is almost never the reading in learned knock on the AP from what I've seen.

i haven't updated my AP or logged my car in a while. They used to have Knock Retard and Learned Knock Regard as a loggable/viewable setting. I guess now it's just changed to knock sum?

Hmm, interesting...

I have a self-tuned MR and even though I see some knock here and there, I have never seen any Learned knock retard. Maybe because I invested so much time fighting knock

As long as you aren't getting CONSISTENT knock at any one RPM ( always getting knock at 5000rpm) 1-2 counts is fine. It must be random though. You will NEVER get rid of all random knock (considering some of it is clutch noise, road noise, etc..)

^this. couldnt have said it any better myself

if you update you accessport they did change it to knock sum and 1 knock sum is .35 of a degree its alot easier to log and read
