It seems to me with turbine manufactuers trying to extract more and more thrust from existing size turbines then surge problems at critical altitudes and temperates can be a real problem.The fix that JetCat have done to the 180RX ECU mapping might be fine hear in the UK at sea level and our moderate climate but be unuseable in Saudi, Denver Colorado,or parts of high altitude South Africa.
I wonder if it is possible to have different ECU mappings user adjustable depending on your location. Not just fast throttle responce but different mappings you could select yourself.
Maybe this will be standard in the future and must be technically possible.

That's indeed a problem with these "small size" upgraded engines. I made my GR180 with 19kg/42lb thrust in same size P80 cannister and increadable, superfast (almost scarry) throttle responce at sealevel, holland. Great for escape's should shortfinal be too short....
Next thing I'm in Dayton at the JWM, very hot and a bit high elevation at 1000'ft. All fast responce was gone, had to regulate acceleration from just 2 sec's back to 7 sec's to prevent surge/stall. Best way to cope this is a superfast electronic feedback system in ecu which regulates mapping instead of a fixed one. Of cource this commes with a price, I think AMT has this system. I saw Marijn's F16 with AMT pegagus which had much slower acceleration than normal which seem to regulate itself. Jetcat seem to have a fixed mapping for all engines. I don't think manual adjustable mappings are the solution, a self regulated mapping is. But that's up to the engine manufacturers I guess.....
