So one driver, Got a question then, the 1227808 (Au) version is the
same as a 1227165 with out a serial driver, right.  Then how come they sell
V-8s with that ecm.  They fire all 8 at a time off pins D15+
D+16.......
Or are you possibly wrong, or did I get some bad info about what an
808 is??????????
Worst case senario is making a new output What 2 resistors,
and enough for a LM 1949?

I can e-mail ya a delco manual showing the 8 injectors off the D15+16.

I'm too ignorant to know what it looks like, if it works it works.
