RE: single vs double batch fire



The bin I'm currently using uses single fire for low bpw..... when bpw gets
so low it switches to single fire..
Gonna play with it when I throw the 30lb injectors.

	Looking some bins and the air fuel mode words, working on a
different
	problem i have found  that (89 Code) only the 305 5 speed bin uses
the
	single fire mode.  All other F&Y body bins that I have looked at use
double
	fire mode.
