2 step question
Since im seeing some knock on the 2 step would the ecu switch over too the low octane map?
And load percentage does the motor usually see?

It's normal to have knock, when 2step rev limiter is activated
ECU will not switch to the low octane map, as far as I know..

-15 is WAY too much, but aside from that the ECU won't pull that much timing anyway. The IX is limited to -10 and the VIII is limited to -8 or something I think.
To get 15 psi on the 2 step you can run +6º or so ... no need to pull that much. I get knock anywhere above 13 psi or so anyway.
