So order of events today:
I wondered previously what the seals
where like so having received a new $22 pressure transducer I took out
trailing plugs and
grabbed some pressure data while cranking.
See
plots in WORD file attached - (File to big, I’ll have to reduce before
posting)
All faces around 80psi when cold. Rotor #2 has one pulse down by max of 6
psi compared to the highest pulse. Does this mean that side seal is
leaking?
We then went after 3 key possible problems:
1st being
Engine monitors holding Injector #1 open so:-
A. Disconnected Dynon engine
monitor to isolate it as a cause of disturbing Injector #1. No change.
B.
Disconnected EM3 to isolate the same as above. No Change.
2nd being
Pulses in the intake manifold messing with EC2 fueling.
We inserted a 0.6mm
restriction in MAP sense line. (This line then ’t’s’ of too A and B Computer
MAP’s. No Change.
3rd Renesis CAS generating higher input voltage.
Tracy recommends 1K across CAS’s.
I think this mod may have been done. See
photo of EC2 PCB below pin 4 & 23 both tied back to pin 22 via something
inside the heat shrink.
Note to Tracy. - Did you incorporate in your
code any way of knowing if the EC2 entered a watchdog routine?
So I’m stumped for the moment.
At least we know more of what the
problem isn’t, Which is helpful.
Appreciated any
input.
Cheers
