And they do test a lot, even different exhaust changed the way knock sensor worked.
He did not treat knock sensor as tuning device, more like a suggestion.

True, but remember that the WRC engines are alot "noisier" than ours. Solid lifters, straight cut tranny gears, ect all create more noise to filter out to hear a true knock.

As for the last statement, definetly. If you crank up the advance and hope the knock sensor saves you, good luck.
