Rotax 914 Turbo - TCU light Blinking

[Turbo_Boss]

Hello Guys,

 

Here is my problen with my ROTAX 914 Turbo

 

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 carburators, start the engine and everything was OK. Since is was late, I dont fly it.

 

Today I start my engine ROTAX 914 Turbo and during the warn up, around 3 minutes of engine runing at 2,000 RPM, the Ambar 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 Presure: 6.5psi

 

Engine RPM: 2,000

 

Oil Temp: 95�

 

EGT: 1,000

 

CHT: 120

 

I was checking the Rotax 914 Trouble Shoting Manual and its says that if this Ambar 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 recomend me to start looking for the problem?
