Hi guys

how are you

hope you are fine

I have c7 2015 header , cold air intake , thermostat and upper pulley

when I went to tune my car


I was looking at the tuner and see what he did

I saw hi doing something strange , he was adjusting knock sensors sensitive for each cylinders

do you think guys he should do that's with only bolts on

kindly look at my log file for normal driving run and full throttle and also tune file

I wish you advice me

regards

Faisal,

Its not uncommon to soften up those tables on that car. Since a knock sensor is really a microphone designed to listen to the frequency of knock it can also pickup other noises which will trigger a knock retard request. By desensitizing them a bit it can filter out noises that are not knock related.

Thanks a lot for fast response


do you think he need to adjust the knock sensitivities for just bolts on?

the car has no cam or misfire !!

Yes. Keep in mind however from my experience your premium fuel seems to be 90 octane at best. (much more sensitive to knock than US fuel). I'm sure your tuner is well aware of this but just something to think about if you are comparing your car to combinations tuned here.
