Why is the rpm at 4800 rpm trying to shoot into turbo.

Prop is set for 5550rpm.

Waste gate and trottle is calibrated using the lap top .

    Hi Seamus,

    Could you please rephrase your question?

    "Shoot into turbo" is not a term we are familiar with, so we want to make sure we fully understand what you're asking.

    Thanks!

    when flying at 4700rpm or 4800 rpm if I want to increase to 4900 rpm  it will not do so but will try to go into Turbo

    Hi Seamus

    The MAP for the 914 shows that this is a turbo "boosted" engine, not turbo normalised.  In looking at the data the engine is boosting to hit the setpoints shown in the data.  Even if you are at a low pressure day, or altitude ( up to 5000 meters) the TCU will hold the wastegate closed enough to hit the MAP to RPM value.  

    Think of this, without a turbo this engine is a 1211 CC 80 HP engine.  

    Cheers
