Hello JetJoe Owners,
Anyway, I probably have the ECU settings out by a mile now. so I need help by asking a few questions.
1) So, does anyone know the default settings for the FADEC for a JJ1400? Factory settings?
2) Also, any JJ1400 owners who don't fly at sea level. How much tweeking do I need for our elevation?
3) what are normal spool up and down times for JJ1400? We were comparing against a Wren MrkIII my buddy was running beside me.
4) Any idea what caused the fireball? What did I sc**w up?
5) what is the normal start up time from when the kerosene kicks in till the engine hits idlw at 50K?
6) Or should I just give up and call this engine a boat anchor????????
7) Who or where can one call/email for technical support? The JetJoe email address is full and is not accepting any more emails.
I would GREATLY appreciate any help I receive. Hopefully, it will only take a week or so to build new rudders......
With much appreciation,

Hi Greg
What a memory
I'd forgotten those early posts [8D]

See previous posts

Not sure any manufacturer adjusts FADEC for elevation of customer, refer to Gasper for suggestions.
3) what are normal spool up and down times for JJ1400? We were comparing against a Wren MrkIII my buddy was running beside me.
Better to have borrowed the other flyer's pump and FADEC, to compare only
4) Any idea what caused the fireball? What did I sc**w up?
[:-][:-]The fireball occurs when excess fuel enters the engines, has insufficient oxygen in the chamber and the fuel and flame front moves out through the NGV in to the outside where there is plenty of air to burn. Nice flames
Causes (in no order), failing battery cells, poor or worn pump (get a Peter Hausel or Flightworks), FADEC ramp too high, accel delay no high enough, stab delay not right, one or more needles blocked on fuel manifold, the vaporiser sticks were the old non inconel curved style and have melted.
5) what is the normal start up time from when the kerosene kicks in till the engine hits idlw at 50K?
Depends all on the FADEC settings, pump and starter speed, but I'd guess from fuel entering the manifold it will be less than 20secs to FADEC showing 'running'.
