single vs double batch fire

[Mike Rolica]

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.
