Default Knock Sensor. Easy question

Hi again:

I'm getting a bit of a ping when I punch the gas pedal, so I switched to a higher octane and it still pings a bit. Could it be the knock sensor? If I change it, how it affect my performance? Thanks

no, ping is caused by either too much timing, too hot of spark plug or at times, lean conditions from not enough fuel in one or all cylinders.

on top of obviously too little octane for a given compression

91 octane should be a given in the corvette

have you checked the timing? do you have an aftermarket chip? do you have mods on the car?

i would check to see if the timing is set correctly first before anything else.

If the KS has been removed and replaced, I know for a fact that it's possible to overtighten and get it too sensitive.

If nothing else has changed (including fill-up source), I'd be inclined to look at the ESC as the culprit. Or, change stations to be sure. As stated, use 91 (or higher octane).

In the winter, I sometimes wonder if complaints could be related to moisture in gas.

Or the engine could be on it's last legs. We tested it with the thickest oil we could find and that was able to bring down the knock count and the oil pressure.
