Power FC Knock Level

[Auss15]

I'd be very happy with those readings, sounds like you have a very safe tune. My knock levels are between 10 and 25, which for an SR is considered normal

Yeh those readings are fine!

 

[R-Spec]

wonder if they change if you do the sensor bolt up tighter :wack:

 

[Matt_S]

Yep they do :wack:

 

[R-Spec]

thought they would... difficult to compare unit-less numbers then from case to case. If you've had a good map done with a tuner thats professional and uses DET cans (listens to DET in headphones) then you should be ok. When your getting it mapped check the PowerFC DET number (for your car) and write down safe limits with his advice

Would you guys think I should lean it up and tad more for a compromise knock of 20-ish?

I'd like to see my FC around 9km/ltr if not better? :nod:

I don't see why you should lean it up and get more knock.
It has already been tuned to almost perfect.

Also, If you lean it, exhaust temp will rise and the engine will be
warmer thus affecting oil temps, water temps and also engine bay area.

Whats your FC now km/ltr ? how many K's per full tank ?
