Interestingly from the EC3 manual:
"TACHOMETER CONNECTION
The EC3 sends engine information over a serial link to the EM2
engine monitor (if used)
including engine speed and many
other parameters. It primarily derives engine speed and fuel flow
by monitoring the injector drive signal on J1 pin 3. If you are
not using the EM3, this pin may be used to drive a tachometer if
it is capable of working with a one pulse per revolution 12 volt
signal. Consult the maker of the tachometer you are considering
for compatibility with this specification."
This is what lead me to think I didn't need to connect the EM3
tach input to the EC3.
But I don't see engine speed in any of the 28 parameters above,
unless it's TPL and TPH. Still haven't figured out what "TP" is.
Timing Pulse? Or maybe
IPWCR?
EM3 does display MAP correctly, just no RPM. Need to review the
EM3 program.
Last night I also found I'd reversed the A/B switch. Program
states: Switch open: A, closed: B. If B selected and hear relays
in EC3 releasing when turning off power to it.
PFUN only displayed in mode A, apparently. Happy to find that I'd
at least wired the mode switch correctly.
