Hi Chris,

I have had my JJ1400 since early last year and apart from a blocked fuel needle and a rebalance
it has behaved flawlessly.

By the way the rebalance and needle unblocking were carried out after the videos below were taken

apart from a blocked fuel needle and a rebalance I have not had a problem.

It does sound from your engines symptoms that it could have been caused by a faulty starter motor.
If the starter motor was dragging on the compressor nut then the FADEC will keep pumping fuel at
an ever increasing rate to get the RPM's up to idle thus causing the high EGT's.

The setting I used on my FADEC ECO with Hausel pump are below.

Full Power Speed: 160k
Idle Speed: 45k
Stop Speed: 28k
Start Temp: 100ºC
Max Temp: 800ºC
Acceleration Delay: 30
Deceleration Delay: 30
Stability Delay: 40
Pump Start Point: Auto+1
Pump Start Ramp: 6

These are the settings that you should only need to adjust, you will probably find that with the FlightWorks
pump you might have to tweak a few setting but the one above should be a good starting point.

Here is link to a discussion of the JJ1400 and a few videos I posted a while back (forum name is GROGGY).
