It's roughly 3 counts per 1 degree (2.8x IIRC). The Octane tables also have some effect on timing retard, but in normal use they don't really have a significant impact (we don't knock for loong periods of time, DSMlink resets octant on every start as do most chips, etc). The max the 1g ECU will retard is 43 counts, or 15 degrees. 2g max retard is 12 degrees, but I'm not sure what the max count is. I believe it is also close to a 3:1 ratio, but all one would need to do is take a log of raw knock counts and knorck retard and do the math. The important thing is that there is a direct relationship between the two, and the octane tables can affect it as well by a couple degrees but rarely will.
