The volumes will have to be dialed in to your application. Start off with 0.05 gallon in each of those. When you go to change from one fuel type to the other watch your fuel trims as the transition occurs. If stoich changes to quickly the fuel trims will show a sudden change due to the wrong stoich ratio being used for the fuel in the rail. Same will occur if it changes too slow. If you are on gas and fill up with ethanol and your fuel trims go positive during the transition then delay volumes are too high meaning it's not seeing the ethanol quick enough. Conversely if the fuel trims go negative during the transition then the delays are set too low.
The Axis don't get changed. They are fixed axis on your tune. What I'm saying is HPTuners has the axis labeled wrong. The labels are actually 0,10,20,50,80.
