Knock Control Box?
Hey guys,
First time pulling the engine harness through the firewall on my current rebuild... thought I had all the plugs unhooked before I started tugging. Well I folded the knock control box circuit board in half. lol.
Is this needed to run my car safely? I have the last minute things to install/check before my car is ready to fire up for the first time again. Will it be fine running and driving around without this until I can source one?
I'll be in the break in miles so no boost and well under any real load and 3k rpms.

the s4 knock control system is pretty crude/ineffective by their own admission:
The s4 system used an analog system in that external box, and a knock sensor in the middle iron. Mazda redesigned the knock control logic and integrated it directly into the s5 T2 ECU while also relocating the sensor.

Gotcha... well from what I'm reading it really never made a difference anyway due to other vibrations and "noise" that it was ineffective? I just want to be positive b/c there is no box plugged in at the moment and I'm finishing up my rebuild. I will hopefully have her started today and want to start putting some miles on it if it goes smoothly.
Thanks for the reply!
