You tuner needs to be addressing this issue , you do NOT want to turn off the KS

^Totally different boat.


Also begs the question of, 'how do you know how much timing the engine wants'?

LOL i didnt run the knock sensor on my car. Chris is still driving it now.just a good tune i guess ;)
Knock sensor would pick up the wastegate opening and it would pull timing hard in between gears when i would slam them.

Correct, same thing happens on megasquirt so I done away with it. Most non-oem boosted cars do away with the knock sensors. Cars that come factory with a turbo (srt4 comes to mind), have had more success with knock sensors.

Most cars do away with the KS because they dont work properly from the start or the tuner doesnt know how to adjust for it , the KS is basically the last line of defense no good tuner would ever turn off a knock sensor if it worked right and the Focus sensor works perfectly once you know how to adjust it

MS is a turd to start with doesnt shock me that the KS cant be adjusted properly in there

I have no issues running them with big HP and shifting hard , there is actually a way to adjust for that in the software if you tuner knew how to adjust it Jim

Tom this happen even when we tuned. We started remote Tuning the first time and you said you won't remote tune it cause of the ks. I had to drive to your shop so we could tune it there. Knocks sensors are junk.
