Its my opinion to leave the knock sensor on as it is a HUGH safety for your engine , yes you may see some knock on gear change but thats perfectly normal because of tip in timing adding timing on tipin in among other things

Please leave your KS on at all times unless you have a SVT

I agree a knock sensor is a nice backup if something goes wrong (gas, boost,etc) but the focus ones are not calibrated right. they pick up the noise from the drums on the dyno, road noise, wastegate, and shifting.

Pulling 5.5 degrees (not 5 like i thought) is not normal. the car fell on it face everytime.

Also you know as well as i do that chris focus blew the ringlands with a J&S on it when you tuned it. there was deto marks on the piston head. I bring chris car up cause it had the J&S on it and still went. I would love if we had a company that would make a nice External knock system for our cars that get away with the factory one.
