Does it ping with premium fuel. Might need to check timing.

Any codes set? If not, trouble shoot the ESC, anyhow. The ESC should trigger the ECM to suppress the knocking.

RACE ON!!!

The knock-sensor should be stopping it but until you get that fixed: Use better gas and less timing advance. That will protect your motor. If it starts any pinging, take your foot out of it now. A little detonation can do a lot of damage. One more cheap thing to do. Add two bottles of fuel injector cleaner to the tank premium gas. If your fuel system is a little dirty, it could be leaning out under load. The computer should still stop the pinging, although obviously it isn't.
