In comparing the pinouts between my 82 Fbody manual, 84Ybody
manual, and the 747 pinout from the archives, it seems that the extras from
the crossfire all relate to emissions. Is this due to the 747 being a truck
ecm and them(trucks) having less strict emission?
I'd bet the 91 emissions for a truck are much tighter than a
82 car.
How did you that made the conversion handle this? Just drop
the systems like evap and air injection, or find other ways of running
them.
I didn't have that problem <g>. Evap is in 747
as I recall. Might get away with just a straight air injection without
the cold engine switching. As I recall (gee that sounds boring), the air
magement valve is just to use air by the ports hot, and the cat cold for
lighting it off. Unless you need to pass a cold engine start emission
test just leaving it so that you have it right for warm engine, is something I
won't tell anyone about.
Between the manuals, they list high gear, 3rd/2nd gear
inputs, and the 747 has a high gear input. My 82 Z28 has a '84 T-5 5speed with
no connections other than backup light. What function does this connection
relate to(anything other than converter?)and should I leave it disconnected or
tie it to something else?
I thinks your comparing auto tranny 747 to manual xfire, try
manual 747 to manual xfire.
