The thing is that there are plenty of cars that dont and never had a knock sensor and there are new cars today that dont have them, they are a fail safe to keep the engine from allowing the car to detonate when it thinks that its going to pre-detonate.
As long as you take care of your car and not being a retard, any car can run just fine with out a knock sensor. None of the pre computer cars had a knock sensor and they all seemed to run just fine.
I took a picture off google images of a piston with a hole in it.
You can't foresee everything, for example: bad gas, failed MAF, etc.
Pre-computer cars burned holes in pistons and/or didnt run as advanced timing.
Let me ask you this: Why would Nissan install the sensor if it had no practical use?
Good gah. Why do I even try?
