Default Need some help from someone....Rogue!

This problem is annoying

It makes me want to rip off the Gen 5 and put back the Gen 3 and run the set-up I had last year.

Huge KR

14 degrees

But only if I stab it a little bit to bring the revs from 1200 rpm to 3000 rpm, (A/F is 12.5 when this happens) then I can let off slightly and the KR drops to 0. I can then get back into it and go full throttle with only 1 degree of KR

I can go WOT from a stop and I don't get any KR.....maybe 1 to 1.5 at the upper end.

Power also seems to drop off at the top of 2nd gear but I don't see any significant KR

A/F at WOT is 10.9

The Injector pulse width does not go above 18.

What else should I be looking for

Have you tried pulleying up to see if your part throttle KR goes away?

I am running with the largest pulley I have. A 3.4".

It makes no difference if I run with 100 octane either.

I can't believe your car is knocking with a 3.4 and 100 octane. If it is showing a lot of KR then it must be false knock that the sensors are picking up from somewhere or you have a fueling problem. Have you checked fuel pressure? What are your LTFTs when you see the KR?

Are your KS'* wrapped with a false knock kit?

Fuel pressure is good. LTFTs are -7 Like I said it is running 12.5 A/F when I get the 14 degrees of KR and it isn't at WOT, it is at half throttle stab from 1200 to 3000 rpm.

No I don't have the KS wrapped. I didn't have this problem before the Gen 5.

Take off the SC belt and see if you still get the part throttle KR. If not then either the KR is real or the false knock is coming from noise in the blower.

Haven't done it yet. Too many other distractions.
