Hi Chris,<= br>
Just wa= nted to mention that when you used the "Injector Disable" switch to<= /span>
turn of= f the primary injectors - the EC2 will then automatically turn on the
seconda= ry injectors regardless of whether you are above or below the staging=
point. = They in effect become your primary injectors. This is assuming you
have th= e injector switches wired per Tracy's recommendation and of course
the "disable" switch is ON for your secondary injectors.

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