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.
