Help EVO gurus...

I have the Bucshur Stage 4 setup and Stage 4 SAFC2 settings, is the knock normal at 160 - 200 when its at idle?

My knock reads 160-200 only when its very hot outside, about 98degrees Farenheight.

How should I bring my knock down to the safe side 20-50?

I also noticed when the car is parked in the shade for a long time the knock at idle is at 30-50

But when you drive it normaly for about 20min on a 98degree weather knock goes up to 160-200 at idle?

The other problem I'm having is when you go WOT and the knock is at 160-200 the engine misfires, feels like a fuel cut.

Is there a solution to this problem via tuning it on the SAFC2?

Thanks for helping me out on this....

Wow thats some pretty high knock numbers, you sure its calibrated right. I never went over 20 on the knock monitor(when I was using an afc), but then again you have to remember the AFC2 is not super accurate when it comes to knock readings.

 

Yes, its calibrated right.

When its at idle on the first start its at 20-30

But when you run it on the hot weather 98 degrees it bumps to 160 on idle.

 

i have buchsur stage one (with safc2) and mine runs high during the day too. im not shocked to see my knock at 80-90. only thing ive heard is that it is super inaccurate like gofaser87 just said.

 

The General forum is not the place for tech questions. Moving this to the Engine/turbo/drivetrain forum.
