Hello JetJoe Owners,

On the weekend, I had a brain fart and fooled with my ECU settings. I purchased the engine mounted on a airplane. I ran the engine with the settings as it came. I should have know that EasyTiger would have it set right but......He lives in New York and I'm in Edmonton. An elevation difference of 2000 ft. So I figured that some tweeking could cure three quirks I thought I had. These were:

1) slow ramp up from 25K to 50K on start up. It took between 30 and 45 seconds.
2) Spool up was around 10 seconds
3) spool down was around 12 seconds.

And we occassionally noticed a slight hint of orange flame as it spooled either up or down.

So, I read the Fadec manual. Seemed the settings for a Wren 54 would work for a JJ1400. Also, as I understood the parameters, they looked like the right direction to go. Well it wasn't. The engine ran OK on the starting stand. And, it did seem to spool up and down faster,BUT. Three times while taxing, the engine exploded a huge fireball out the tail pipe and shutdown. The last time burned the rudders off the Reaper. The fireballs occurred while wiggling the throttle up and down at a low setting. Trying to obtain a nice roll out speed on the taxi way to the runway.

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,
