Benching ecms

[Bruce Plecan]

Well if your playing with a 747 onna bench,  if you can apply a vss
of at least 90 mph all the auto tranny .bins, I've found have the TCC
apply at this speed.  
    The manual tranny bins turn on a shift light that runs off of the A7
pin which is used for TCC solenoid for the autos.  It works mainly
off the TPS.
    Also, the cylinder number select is in the prom on the 747's.
  I've tried several netres, and they don't affect the rpm displayed 
whereas proms do affect it.   
More to follow.
Cheers
Bruce
