Whew, that's not what I have.  What FAQ are you
referring to?  And where did you come up with (I
assume you mean) x86C6?  
According to my hacking, bpw is not a single byte
value.  It starts with a "Base Pulse Constant" that is
a 2D lookup with EGR flow.  This table is at x8761. 
If you go through the math, this gives you a injector
constant of 14.9 lb/hr ... IIRC.  

Have you changed your injectors?  If not the point is
probably mute anyway.  
Also, how did you pull this ecu together?  Do you have
a hack you could share with the class?

My $A1 stuff is here if ya wanna check it out (It's
not ready for prime-time yet).

PS  I'm fairly certain $A1 never control and auto
trans.  Perhaps you're thinking of TCC control?
