engine operating hours measuring

Hi I'm using an iEFIS to monitor a Rotax 912iS Sport engine using the CAN Bus communication. I'm finding a difference of 5-6% between the engine operating time measured by the iEFIS and the time measured by engines ECU. What is the logic in the iEFIS for the time measurement? When does it start coun...

This difference of 0.5 bar is greater then the allowed Rotax tolerance of 0.2 bar. In some data analysis software I worked wit...

Differential fuel pressure

Hi I am running a Rotax 912iS engine on an iEFIS system. The Rotax fuel pressure regulator is regulating the pressure relative to the air pressure in the airbox, and keeps a 3 bar pressure difference between fuel and air pressures. Since I could not allocate an adequate and reasonably priced differe...
