I'm flushing the final quirks out of a new G3X install, and the last one is an inop fuel flow indication. I have the SDS EM-5 ECU, which has been happily supplying fuel flow to my old AFS4500 panel for years...but the G3X is reading 0gph.
Can anyone who has successfully connected the SDS EM-5 (or I assume EM-6 is the same) fuel flow pulse output to the GEA24, confirm my configuration is correct?
- EM-5 pin 2 "brown wire" -> GEA24 J243 pin 23 "Fuel Flow" (I have confirmed continuity of this wire from pin to pin).
- No other fuel flow connections (gnd, +12V, etc)
- GEA24 Fuel Flow input active. I have tried setting it as a "Floscan", an "FT-60", and "Custom 0-5000Hz", and K-factors of 304, 3040, and 30400 (my former setting was noted as "304").
My EM-5 also had a software update to support the newer style programmer, so it's possible the issue lies there, but I unfortunately don't have an ocilloscope to test the pulse output is active.
