Howdy guys, I've got a car here I'm working on that I'm having a fit trying to get straight with fuel. I'm using the Ver 3 ECU w/ the hand controller and the cartridge software (V3.1). The Aux Injection staging setting is confusing and the manual is not very informative on how exactly it works. It appears that it's got conditions it has to meet before engaging the secondary injectors and that's what I'm trying to nail down (appears to be 4500rpm). Is there any newer version of this software that's more intuitive or allows the user to set more settings according to any of this aux injection staging or is there anyone here who's got experience with this ECU that knows more of the specifics concerning what conditions must exist for staging in the first place? I understand how the Aux Inj Staging % figure works; I just need to know why in the world the car acts the way it does. I'm having to do some pretty harsh manipulation of the fuel map to get anywhere with it.

Thanks a bunch,

B
