The adjustable parameters on the intune 1000 DCX includes spark advance adjustments. What is the difference between WOT spark, and WOT MBT spark? And if you advance the WOT spark, is the increase in timing over and above the factory setting, or is it from 0degrees? There is nothing in the user manual to explain any of this. If I can pick up some horsepower and torque by adjusting the spark advance, that would be great, but I don't want to do something that is going to have an adverse effect on my engine.
