JT-Imports

Ok im just going to add a little more even though this is answered.



Apexi themselves say the communication between the knock sensor and the PFC isnt the most accurate thing in the world. Things you can do to be safe. Retorque it when and if you can along with a little lock-tight, and like EVERYONE mentioned monitor it.



Just watch what it does, the knock being high at first start (doesnt matter) I had high knocks changed my oil a couple times that worked. So what you can do also if its around the time. Change plugs, wires, oil and monitor. Could be nothing could be something.



At 130 knock though you should be hearing some engine noises too.
