If you have the engine apart still, try checking that you have even fuel flow to all the fuel injectors. You can do this by taking the fuel ring, running gas through it and then lighting the needles (it takes only a veyr small amount of gas). If you have an uneven flame from one or some of the needles or no flame, then that will be causing a hot spot, which may be aligned with your EGT probe.
The ECU will be holding the rpm due to high temperature. If the pump was a limiting factor, then the PW would continue to increase as the ECU tried to get more fuel flow.
Good advice, if all thing mechanical are OK
Try Gaspers advice below (he built and designed most of the current FADEC-ECU working today)
1) Test if your TX is correctly aligned. Just go to the second screen on the fadec ("Pulse=.." ) and check that at full throttle the percentage at right side of the first line is 100%. Then check that at "OFF" it is at zero and the value increase linearly with the throttle movement. If not, check your TX.
2) Set the throttle curve to "Full Expo".
3) Set the accel delay to 60, decel to 20 and stability to 100.
4)Start the engine and accelerate to full power click by click.
5)Once at full power look at the pump power (right side of the RPM reading), and anotate/remember this number.
6)Set idle.
7)Move to the menu "pump limit" and set the value to a 15-20% higher than the value you read. If the engine arrive at full power at, say, 300units, set to 360. If you do it with the engine running could be that the rpm drop at idle, simply ignore it, it will self calibrate in few seconds.
8) Go to full power again. The engine will take longuer to arrive, wait for that the fadec calibrates the full power again.
9) Once at full power, decrease to idle, but by one click at time, waiting 2-3s between clicks to give time to the fadec to calibrate the curve.
10) Once at idle, calibration is done. Now you can play with the throttle. If you find that now it is too slow, just decrease the accel delay to have faster accelerations and decel delay to faster decelerations. Usual values are <20, but this depends of your taste.
This is the "complete" procedure. No need to play with anything else.
