Power FC knock sensor

[JDM-DC2R]

Reads about 10 after start up the car, around 10-20 on the street driving normally and about 30-40 if i rev on the street. Does it sound ok? Or i need to get it retune again?

Anyway how high is consider "HIGH" ?

You really need to ask the person that tuned your car or give Toda AU or Dyno Dave a PM about it.

IMO it's okay.
on my GTR i was averaging 30-40 everytime a i give it
and the Knock light on my dash never came in.
the car was on spot on tune and it was running clean.
so for a powr FC 10-20 is normal for street driving and 30-40 is normal for reving

adrien at toda told me anything above 40 is not so good, he tuned it so he would know, my one get to about 30~35 on a hot day when i pull big loads, go see him if you have any doubts hes the man

anything below 50 is alright, dont forget that the knock sensor is not always acurate which means if you get 100 knock it dont mean ur engine is stuffed

below 30 i have been told....... when i was between tunes i got told to watch it and that it was bad if it goes over 30ish.

dam, i guess 80 is no good then. Don't drive to brisbane from sydney!!!

Above 60 is dangerous. Below 60 is safety. Between 30-40 is normal. If the reading show above 60, the cpu light will flash. You may try to retard 2 degrees of the timing on that point.

Is this boosted or an NA car? If it's NA, then mean best torque will probably be further back from knock point than 2 deg.

[JDM-DC2R]

It's a NA car and it only reads 60 when i really rev alot
normally it reads between 10-30

Rev it a lot? Do you mean under load or just free spinning it?

Hmm.... when i rev to 8000rpm on 1st and 2nd gear or even 3rd
I rev on the streets or when i enter the freeway
