Sandor and I did some preliminary "fuel consumption" tests today on the CTU. Sandor did a test setup using his Rebel Hot with a Kingtech K70G2 in it. He used an external fueltank with precisely 1 liter of fuel (approx 820 gram) and did a engine run with "simulated flight maneuvers" with varying throttle settings (you can almost see him doing this if you close your eyes
)
The fuel consumption was measured using the CG wizard as well as the Digitech FTU unit. The fuel consumption from the CTU was logged together with the FTU measurements (basically we used the FTU and the CG wizard to verify the calculations I do in the CTU). We then extracted the log from the Jeti transmitter.
The result was pretty good! We consumed 1 liter of fuel and the CTU claimed we had used 1041 mL of fuel, so very close!
It is worth mentioning that the calculations done in the CTU is solely based on pump information from the ECU as the Kingtech ECU does not provide any "fuel consumption" info by itself.
Below is a few pictures of the setup and a screendump of the jetilog.
More to come later....
