Ktuner Crazy knocks and misfire

[JimmyGangSI]

I was wondering if anyone else was having the same problem as me, I tuned the car for 21psi and turned off artificial knock control. While I was doing pulls I was getting 41 knock count total and misfire cylinder 1-2-3-4 every pull. Then I change it back to factory to see if I was still getting knocks/misfire left and right on ktuner graph. I was getting 10-20 knock count total and still misfire on all 4 cylinder but the car felt fine. I was wondering if this is normal for 11th gen si or something was wrong with ktuner application.

But like I said the car felt completely fine no check engine light or anything weird was happening just ktuner graph seems off.

This is not a significant amount of reported misfires / knock count. The sensor is VERY sensitive. There are no issues with your car or either tune. If you any significant amount of misfire your check engine light will flash during the occurrence and eventually stay illuminated when/if an error for the misfire is reported by the ECU.

Consider it a false alarm. Enjoy your car.

We relay data from the ECU. 41 for a total count is nothing and the ECU will alert you with a CEL flash or error code if there's a serious problem.

Hey! Had the same problem. Have u installed an aftermarket motor mount lime 27wons? I just retorqued both bolts and All of my knocks went away. I was freaking out because the car drove fine but I did notice a significant increase in vibrations leading me to retorque the mount. If you don’t have one, just grab a 19mm (or 3/4?) ratchet and try tightening the front motor mount. Cheers
