My merlin 160-2 has a low acceleration rate : 7 seconds from idle to full RPM (118000).
It seems that usual spool up time is 4 sec for this turbine.
I cannot change the acceleration delay in the ECU as this Fadec is access limited. I can only change max rpm in the run parameters.
One of you could help ?
Thanks.

If it's a new problem, I would suggest it's a blockage and you need to look at your pump voltages. Just a thought anyway. Filters? Are they clean?

I'm not sure that it's a new problem. It's the first time I measure the spool up time precisely.
I already checked my installation : fuel lines, filter.
I tried today another fadec (a generic one, not limited) with standard parameters for the merlin, and the spool up time was normal this time at 4 sec.
So I think that it's a fadec problem.
