I bought a block that did not come with the Knock Sensor - the selller took it out. So before I go buy one I am wondering if I would really need it since I am going turbo with Hondata after I break the motor in.

Will difference will it make if I use it or not?

Thanks.

 

Bump for some opinions

 

Yes you need it. And yes its important.
If you run hondata it is not something you must have but is still recommended.

 

I think the only way to run the knock sensor with Hondata is if you're using a P72 or P30 ecu. I snapped the plastic on mine a while ago, but since I have a P28 and Hondata, it doesn't matter. When inspection time comes around, I'll have to get another one so I don't throw a code with my stock ecu.
