It would; however, most manufacturers "dumb down" the timing to be on the safe side. It can *usually* be increased safely by at least a couple of degrees, but yes, there should be knock detection. I can't speak for all cars, but my car has two timing maps (one standard and one for when knock is detected). You'd really have to crack the ECU's coding to know for sure. I'd recommend checking online forums for people with similar cars who might have already messed around with the ECU.
