Has anyone with the "new" red ECU foregone the red cubes and hooked up the Dynon Skyview for fuel flow calculations? As I understand it the Skyview does not have the ability for duty cycle as a fuel flow input. There are two wires from the grey sleeve in the ECU loom for fuel consumption, a white/blue which outputs is a duty cycle (no good) and a white/red which outputs 48l/hr or 170 pulses/sec. I assume the white/red wire is correct. That wire should go to P14 on the EMS? Has anyone with a UL and Skyview done this and is it working correctly? This topic is hazy to me.
I have a 350i engine and it did not come with red cube flow meters. So I just connected the white/red wire from the ECU to P14 on the EMS. Once this was done I had to calculate the new K factor to put in Skyview. Since 170 pulses/second was equal to 48L/hr, I converted liters to gallons and 170 pulses/second to pulses/hr and doing the math it came out that 1 gal/hr was equal to 48265 pulses/hr. Once I had this number, I went it Skyview and entered the new number. So far it seems to be giving me an accurate flow rate. However this is based on ground runs and taxi tests only. I just completed my airworthiness inspection yesterday and it will be at least a couple of weeks before I can fly and get some flying data. Hope this helps.
Thanks Larry, that is what I needed. Congrats again on your airworthiness inspection. Now the fun begins! Let me know how it goes. I am doing my first taxi checks this week, so it won't be long for my Airworthiness as well.
Guys, Thanks very much for this info. I had it wrong and never would have figured it out without your input. Tom (old not very computer savvy guy)
