To Tracy,

Question no. 1  What is the size of the Programming Control Module, I
understand that it goes on the instrument panel.


The control panel is 4.7" W x 1.7" H

Question no. 2:  I will be using 4 AC Delco coil/igniter units in place
of the Mazda ignition modules.  Will we get the wiring instructions for
that?

Yes.  Make SURE you specify that you want the AC Delco coil version when
ordering.  Don't rely on me remembering this email conversation!


Question no. 3: Injector Failure Backup Mode
I am trying to decide if I want to install the 2 switches for that
option but I do not have enough information to make a decision.  There
seem to be two possible failures with the injectors (a) an injector
stuck open, and (b) an injector stuck closed. Are there other
possibilities?

That about covers it.  As far as I have been able to determine,  the most
common failure (which is still very rare) is an open solenoid causing the
injector to stay closed. If an injector were to stay open, there isn't much
you can do about it.

What are the concequences to the engine when an injector is stuck open
or closed?
Can one faulty injector Kill the engine?

Not quite that simple a question, but generally , no.

What if I have a switch for each injector instead of one switch for each
bank of 2 injectors.

Thanks

Rino

A separate switch for each injector would be very akward to handle.   I
would suggest doing it the way I outline in the installation guide.
