Just to mention one ecm ignored so far in the 101 stuff on the late 1227165s 128K prom 0008 ID 6E, you might find a spark table starting at 002D. If you also look at 01C2, 01C7, 01CC, and 01D4, you might find the knock variables, and the math would be similiar to whats been mentioned in 101, already. Diagnostic flags start at 01DD. Bruce
