Scanner not consistent with editor

[Dom]

I did some WOT runs and I had a constant 25deg of timing advance. Some 26s and even a few 27s. In my high octane table I have 24s in the large area where my WOT runs occur. Nothing higher. In order to dial in my timing exactly the way I want it, I need to understant this phenomena.

The problem is that I'm getting 2 deg of knock at certain RPM under WOT, not always. I need to know wheter lowering timing will actually lower timing. Or what other factors also influence this addition of timing to the octane tables. Any ideas?

There are other factors that add and subtract to come up with the final timing value. Usually a 1* decrease on the High Octane table will show a 1* decrease in final timing

How do you figure out from which cells it's taking the timing from?

[Dirk_Diggler]

It should be plotted in your histogram(spark for timing, retard for cells that showed KR)... If that doesnt answer you question can you re-ask it with a little more detail.

Be sure you log the Dynamic Cylinder Air PID
alond with RPM, these are the two spark table
axes and you should see the value from the table
at the indicated coords. If not you have to look at
the modifiers (KR, burst knock, IAT/ECT/EGR adders
and like that).

Thanks for the help. Next time I can get a laptop I'll log Dynamic Cylinder Air.
