Thanks Ed,
That makes more sense that the graph is reading % duty of the HSV. I understand it's an iterative process, I just want a base to start from and I seem to have it now.
Using the 3D graph from Richard if I set his maximum water injection rate of 65% duty at somewhere around 20-25% water:fuel and scale the rest of the map I'll come out fairly close. So at very low boost and medium load you are injecting (~5% duty on graph) or 1.5-2% water:fuel.
Why do you encourage water duty >25%? If you drop below that duty are you getting pulses of water such that each cylinder is not seeing a homogeneous mix of water:fuel. I'm cool with doing it, just wondering want the reasoning is.
