Default built motor knock sensitivity

Hi all,

I have a axis stage 2 SB and was wondering how loud the engine is compared to a stock ej257? What knock settings should I use In my utec for knock sensitivity? The thing is that I am getting some slight knock where I should be and was curious if the engine was just loud.


Didn't know if this belonged in here or the engine management, But I thought I would get more responses in the built motor section.


Any advice would be great! thanks all.

The only real way to tell if it is det or not is with a set of det cans.
I can tell you that on my "diesel", drop in piston motor I was able to up the sensitivity of my Utec by a min of 10 points across the board more in some spots. All so it took me a week just to tune the sensitvity numbers.

Yeah I was gonna rig some det cans up but haven't got around to it. When you said up the sensitivity do you mean MORE sensitive? Anyone with a drop in piston subaru motor have any input on the knock sensitivity?

Bump... I'm very interested in this too since I'm dropping in pistons in 2 weeks.
