Knock sensor question...

Would it be okay to just delete my knock sensors? About a week after the cam istall and dyno tune, the #1 knock sensor went bad. 3 weeks later, #2 goes bad. I haven't changed out #2 yet, because I'm not sure if I should even worry about it, or just get them deleted. Any thoughts??

They may be just fine:
If you have EFILive try this, .

Change the burst KR to zero from 40c to 100c across.

then bump the sensor frequency, and filter. At least this way they are not turned off and just bumped up.
