Tim,
One more thing has occurred to me, you indicated you are
using secondary injectors that are a bit larger than your primaries. In
that case, adjusting mode 3 adjusts the flow to both primary and
secondary. So IF you do manage to get the flow down enough on the
secondary injectors using mode 3 so the larger secondary injectors are not
injecting too much fuel (causing the engine to bog), you may find your primary
injectors are now not injecting enough because mode 3 reduces/increases the flow
to both.
So I would turn on only the primary injectors and run the
engine and use Mode 3 to get the fuel flow right for the primary injectors
(sounds like you may be ok there). Then activate the secondary injectors
and use Mode 6 to adjust the secondary differential - this mode will adjust the
flow (on time) of the secondary injectors without affecting the flow to the
primary injectors. Might give it a try.
As Steve mentioned, you need to try and separate the two
injector systems and try to pin point which one is causing the problem - right
now it sounds like it’s the secondary system.
