Bill,
According to the manual, the flow rates
are:
Red 69-78 ccm/15s
Blue 118-133
Yellow 89-101
I’m assuming the 15s means 15
seconds. So, multiply these values by 4.

What is the actual size of the stock Renesis injectors? I was
under the understanding that the red primary was 295 ccm and the blue secondary
was 610 ccm. I heard that the yellow injectors from the hi power 6 port
were a different size, but have never heard what size they were supposed to be.
Don, did you say you had your injectors cleaned and flowed? What
did they flow?
Where can this information be found? Is is listed in a Mazda book
somewhere?

Mode 6 would handle it
but that is for normal staging only. The 'injector set
disabled' is a special case In which the EC2/3 does not know which set
has been disabled and therefore can't know exactly what to do. It's up to
the pilot to make the appropriate response on the mixture knob if the injectors
are not the same size.

are
feeding the engine almost twice the fuel (for the same engine
conditions)
as you did when on the primary injectors. The engine is choking

too much fuel.
Unless, of course, you have made the mode 6
adjustment to compensate for the difference in the flow rates – or will
mode 6 not handle such a big differential.
