ECU reset

REF> This engine is in an Unmaned Aerial System. Super Big Drone!

The ECU is reset at each power cycle.
There is no master reset.
A Re-Flash of the ECU Firmware might do something. but unlikely.

Does your telemetry monitor the LANE Warning lamps States remotely?
It is not uncommon for the lanes to go into alarm if the voltage sags during the engine start.
If they remain in the WARNING State, the engine will revert to POWER (Not ECO) Mode.
Can you Cycle/Reset the LANE Power remotely after start?

What is the Fuel flow rate, RPM and MAP at various power settings?
This will indicate if you should be in ECO Mode or not!

Good Morning Bill, 

This is in a pretty decent sized drone. Enough to meet Group 3 classifications. 

Thanks for the input on the ECU. Seems we may have a problem if the ECU is not reverting back to previous fuel consumption rates. 

Our telemetry monitor does monitor the faults and relays any and all faults to our ground station. After start we do have a way to cycle the lanes. No faults are indicated currently. I dont have access to drone currently as its at our flight test center but will have access in the coming days. I will be able to pull the files to should the correlation between the RPM and MAP. As for fuel flow rate our first 200hrs we had an average of 2.7/hr and with 100LL we jumped up to 3.7/hr.   We have since switched back to MOGAS and the consumption rate is hovering around 3.5/hr. 

Thanks again for your help. I appreciate it.
