I'm not sure how to check the timing that everyone is talking about, but i think it's the value of spark advance at WOT?
From what I see the value of rpm and my throttle input, I can imagine there's a table from 700-6800 rpm, engine throttle position and interpolated in between the points. So the one way to see consistency is the WOT value (the max value of the table)
Bartly, at WOT, what kind of spark advance number you see? It should be a solid number, mine is 22 from a canned tune procharger. So the KNOCKR at +4 would means that it's at 18 timing? I don't know how a car tuning works but I do tune PID loop 2500 hp blowers, pumps at my engineering job, so I can't imagine this can be whole lot different.
So as long as your Lambda 1&2 at 0.78, Air fuel at 11.8, spark advance at 22, it should be alright to let the ecu pull timing to do its job. Maybe if they use 18 at top of the chart it will show 0 KNOCKR but I'm just talking out of my butt

even my car locked to 16 degrees will show KNOCKR in negatives at WOT at 7000rpmI'm not sure how to check the timing that everyone is talking about, but i think it's the value of spark advance at WOT?

Isn't 16 degree at -2 the same as 20 degree at +2 on tuning?
