Hello Guys,
I hope that somebody that have a Rotax 914 can help me
Last weekend, when I was going to take off, I advance the throttle to full and then advance the lever to engage the turbo, I fill when the turbo kick in for a few seconds but then then I fill the engine loose power like if I move the lever back to disengage the turbo. I abort the take off and get back to the hangar. Thinking that the problem was old fuel, I remove completely the fuel, put new fuel, new plugs, clean the air filter, clean carburetors, start the engine and everything was OK. Since is was late, I don't fly it.
Today I start my engine ROTAX 914 Turbo and during the warn up, around 3 minutes of engine running at 2,000 RPM, the Amber Warning TCU light, blink 3 times and then stop blinking.
The Engine is installed on a Magni Gyro and it has 248hrs
This was my EIS reading when this happened:
Fuel Pressure: 6.5psi
Engine RPM: 2,000
Oil Temp: 95ยบ
EGT: 1,000
CHT: 120
I was checking the Rotax 914 Trouble Shooting Manual and its says that if this Amber TCU warning light blink, its mean that there can be a problem in:
Wiring Sensor
Sensor damage
TCU Failure
Air Box Leakage
So where you recommend me to start looking for the problem?
