knock signal #2 isn't used. Knock Signal #1 is the same as used by the ECU to determine correction but it is generally worthless to log due to the lack of resolution. The reason why feedback knock correction is useful to log is because there's a delay that ramps it back to zero in steps after the knock signal is clear.
