Hi Chris,

Just wanted to mention that when you used the "Injector = Disable" switch to
turn off the primary injectors - the EC2 will then automatically turn = on the
secondary injectors regardless of whether you are above or below the = staging
point. They in effect become your primary injectors. This is assuming = you
have the injector switches wired per Tracy's recommendation and of course
the "disable" switch is ON for your secondary injectors.

So assuming your EC2 is set up properly the engine should idle on = either
pair (with perhaps some minor tweaking of the mixture = control).
