Okay guys, I've been getting different opinions on the knockbox. Is it necessary? Some say yes, some say no. I'm just curious. I'm going to do a t2 swap and want to know if I should get one or not.

Also, if anyone knows how to wire one into the S4 NA wiring harness, let me know.

Are you using a standalone? if not u need to change ur wiring harness to a turbo and use the knock box or get a rtek ecu

 

I also hear that if you're not using the knockbox, you can still use the existing s4 na harness, without going standalone.

 

WTF where are you going to get the nock sensor? Did you rebuild it with a TII Iron? Besides that the FC Knock sensor is basicly useless.
