I think this problem has been masked by the majority of the users since they enter the Fuel On-board and then go through a flight without cycling power. When you enter the Fuel added the display flashes a "SAVE XXXx" and gives the impression that it is writing to the EEPROM but it actually is locking the new value into RAM and this value is not stored into non-volatile memory until its normal EE write in the main loop of the code and this can take anywhere from 15 seconds to a minute depending on if other switches or inputs are received. We did find in the code however that after the Save flashes if you press the "TEST" button it forces a write to EEPROM and you can power down immediately. We are evaluating the best course of action to take to get this information to all the users and also Socatta or to see if a software change is warranted but I wanted to get this to you first. Thanks for bringing this to my attention and I hope you have not been inconvenienced to much. If you have any more concerns please feel free to contact me. Brian
