No, I did not have a wideband on my setup. If I could do it all over again, I'd have a nice wideband and knock sensor

 

I have a wideband runnig all the time. Quickest way to notice a problem and save your motor in my opinion.

 

I have a wideband 24/7.

 

FACT

If I'd had the wideband, and knock detection, I'm fairly sure I'd still have the Civic today

 

probably a dumb question for someone as far into a build as me but... whats a knock sensor? where do i put it? where do i get one? and what the heck does it do?

i dont want fourty incident

 

I would liek o know also about the knock sensor. and also what you guys think about cast manifolds apposed to tubular.

 

i don't pretend to know alot about them, but this is copied from Car-Stuff.com:

A quality Knock Sensor is more important than ever thanks to today’s increasing gas prices. Your Engine Knock Sensor enables your vehicle to obtain the optimum combination of timing and fuel/air mixture to generate power and efficiency and that means less wasted gas.

 

Knock sensor is bolted to the block and detects when your engine is detonating or pre-igniting(or knocking).

 

Only the Y series motors have them, and they're crap. Knock sensors are pretty useless I'm afraid, it's extremely difficult to detect knock via only soundwaves and that's how knock sensors work. Which means that any "abnormal" sounds that the knock sensor reads as knock (which may or may not be detonation) it will retard timing and try to save your engine. Good in theory, poor in practice.

 

I've seen the homemade ones in action and they seemed to work pretty good. I don't konw, its one of those "better safe than sorry" sort of things. Had I been running one, I wouldn't have driven while detonating for so long.
