Staged Injection

Looking into staged injection for mega squirt. I'm loving Tuner Studio - it's great software. I'm having a very rich idle - but perfect afr (wideband) under any load. My new fuel injectors I've been tuning 2 weeks have spent one week on E85, now I'm back to a gasoline tune, where it's harder for good idle afr using the 1000cc Delphi Low Z injectors. I love and need the top end fuel they provide. After working out the dead time I'm looking into the staged injection settings of megasquirt. I'm really liking ethanol - but I'm also interested in opening other doors like meth injection in the future. Right now I'm hoping to get my afr off rich at idle. I'm getting great number's where it counts though!

I'll follow up w/ some tune and data later when I've my laptop charged. Thanks!

What's your planned setup for stating? I'm running a small set of injectos for gasoline then right about 150kpa I stage fully to my large set that has a separate fuel tank that I mix 116 and 30% ethanol into. It makes for a great street setup.
