[Gmecm] Injector Impedences and other Q's (was '747 multiport)

[DV Fagan]

Michael,
Yes, but..
TBI Injectors are low impedance saturated coil
devices.  TPI Injectors are high impedance
non-saturated devices.  That means they like a
modulated current source (Peak & hold).  TBI Current
drivers are on or off.  Driving TPI injectors from TBI
drivers should cause both the drivers and the
injectors to run hotter than designed.
