2011 F60 will not go over 3400 rpm

[69-north]

Hello all

Hope you can help me.

I have a 2011 F60 and the rpms will not go over 3400.
I have cleaned the fuel system with no luck and there is no check engine light.
There is no damage on the prop.
It used to top out at 5600.

Could it be the ECM that is going in some kind of limp home mode?

limp mode should be around 2000 not 3400

What all did you do so far? Saying you cleaned fuel system has no real meaning if you do not say what all has been tested and cleaned/replaced.

If fuel pressures stay in spec at all RPMs then injectors may be your problem.
But a computer hooked up to motor would be a good idea also

Did not do anything else than check spark plugs and they look good and with computer hooked up, there are no faults.

It accelerates slowly up to 3400 rpm and stayes there

So you have not tested fuel pressures and cleaned/ replaced any screens and filters?

[69-north]

No, I have not replaced any filters, just cleaned them with compressed air.
The engine has only run for 15 hours

[99yam40]

fuel pressures at problem RPM will tell if there is a problem with restrictions

Ok, I will see if I can borrow a fuel pressure gauge.

Thanks for your help
