This is physically impossible, as I stated before the minimum mivec for intake is +10* and 0* for exhaust. Since most tunes (stock Ralliart, JDM, GST, gunzo, etc.) idle at those mivec settings you cannot decrease any more overlap since they are already at minimum. Even if you set the numbers to be lower in ECUFlash, the actual will only be 10* intake and 0* exhaust. Try logging actual mivec and you'll see what I'm talking about.
