I guess Ill just get a new oem one or try to find a used one. Cheapest oem one I saw was around $120. Anyone know of a cheaper new one?

 

Search the forums real quick, I'm sure multiple people have replaced them and someone may have a part number for a cheaper one.

I was reading this before

 

That's an interesting read. I wonder if any of the guys touting 'only run an S2000 knock sensor because it's tuned for the S2000 engine' have any issues running the same knock sensor when the internals have been changed (ie. sleeved/bored/stroked)?

 

Good question

 

most tuners i have read about or spoke to dont heavily rely on the oem knock sensor. they either use it as a point of reference to make sure they are not horribly off or they just use a stethoscope style mic for true knock monitoring.

 

I know my Haltech has knock monitoring where it will modify timing if it starts picking up on knock from the OEM sensor.

 

aem does as well. but the resolution and reaction time of the knock sensor is not the greatest.

 

I see... I know very little about the topic; wasn't sure if that monitoring function existed on other ECU's as well.

I guess if you're confident in your tune or if you don't use knock monitoring anyway, a cheaper alternative wouldn't hurt.
