A better way to explain its is, if i put a stopper on the throttle plate to stop it from going beyond about 98% throttle, it would never ping, no matter how quick you stab the throttle and at whatever rpm, no ping, but you open that throttle plate that last 2% and it pings. So when the pedal hit the carpet, its fine, but put more force on the pedal to force that last tiny bit open, and here is the ping. Its not a lot but its enough and i want it gone so it doesnt hurt anything.
