Fluctuation CHT with ROTAX 912uls

[fernanmanu]

We have a problem with right CHT 's information of an EMS-D120 with ROTAX912uls motor. After 15 minutes of flying, it constantly starts to fluctuate from 90º to 124º. Due to this, the motor gets off and oil temperature sensor doesn't dissappear. We have exchanged left sensor by right one and right CHT sensor still marks fluctuation. So, we have dismissed a motor's problem. In addition, we have updated 5.6 version firmware and the problem continues. Do you know what causes this problem?

Thanks

Re: Fluctuation CHT MCR aircraft w/ D180 & Rotax 912s

CHT and oil t° are fluctuating as well as showing high values. MCR aircrafts seem to be known for  overheating. Other sources blame the way wires are being channelled to the Dynon. Any clue as to how the wires should "travel" from the engine compartment the Dynon and other précautions that should be taken.
