After 18 months of no progress, I’m finally back to building (almost).  I have decided on FADEC for spark and fuel, but not getting any response from the Aerosance people.  Is anyone having similar problems?  Is anyone getting good service from them?  Finally, do any of you have experience with Eagle EMS?  I know it’s not tuned to each cylinder, but it is FADEC-like.  I’m looking at FADEC for an RV-7/XP-360 combination…

Kathleen:  

   

We have talked to the Aerosance guys about FADEC for some Legacy engines.  They always refer us to TCM, and TCM always refers us back to Aerosance.  Ref the EAGLE system by Precision, they were supposed to roll the system out by the end of September.  I’m now hearing that it will be the beginning of the year before the bugs are worked out.  The system lists for $7900, about $3000 more than standard mags and fuel injection at today’s price.  

   

Hope this information is helpful to you.  Best of luck.

 I must be too old-fashioned and resistant to change but I

 am not enamored with FADEC.  Seems like a costly option.

 Have you considered things like the P-Mag?



 Obviously you can do whatever you wish and my opinion

 (perhaps not well-informed at that) should not dissuade 

 you from doing whatever you want.  But given X amount to 

 spend on an aircraft, I would think that going with some

 new glass panel with terrain avoidance, great mapping, weather

 etc offers more to the flying experience and safety than FADEC.



 Oh yea, big screen glass too!

And the Eagle system has FIXED ignition timing, hardly state  of the art, or even modern!

magnetos are fixed timing except for the impulse  coupling mode.

How much work are you willing to do to get something FADEC-like? (Almost 

nothing out there is really FullAuthorityDEC.) Tracy Crook (Real World 

Solutions) makes a dual-computer, redundant fuel/ignition controller 

that can work on a Lyc, but you'd have to install injector bungs on the 

intakes & develop your own plumbing to the injectors. It uses automotive 

style timed injection with high pressure pumps requiring a fuel return 

line to the tank.

These guys:

http://www.sdsefi.com/aircraft.html

make billet injector bungs you can use to mount the injectors. They also 

make an injector/ignition controller adaptable to Lycs.

Kathleen,  

I agree with Ron.  

I personally know of 2 aircraft with Fadecs.  One has fallen from the sky at least twice, the other is not working well.  

I fly with that one fairly often, and one time on a very long cross country.  

With 800 hr mags I consistently get much better fuel economy than the fadec as well.  

   

I now have an E-mag on the right and a 950 hr Slick Mag on the left, both are working well.  

Fadec and other systems may be a thing of the future, but that future isn’t here yet.  

   

As always, if your goal is to ‘experiment’ and help ‘blaze the trail’ for the rest of us, then go for it.  

   

Otherwise, spend your $$ on something else.

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  I'll second that Don.  I'll match my engine tuning skills against any  of the existing FADEC systems.  That's why the EFI system I use has a  manual mixture control and in-cockpit adjustable ignition timing.  

  

 Many of the so-called FADEC systems are not actually "FA" (Full Authority)  in that they have a direct mechanical link between the throttle quadrant and the  throttle butterfly valve.  To have any chance of being better at engine  management than a human being, a fly-by-wire arrangement is  necessary.  This of course adds yet another failure mode but that's the  trade-off.

I don’t have any data to pass on.  I got my information from one of the three engine shops that they have set up to sell the product.  Sorry I couldn’t be of more assistance.

Could you explain the reasons you are willing to spend several thousand dollars for a FADEC system on your XP-360?

  

 I am at a loss why new technology is so appealing to people "before" it is even realistically proven reliable in a critical area such as the powerplant.

  

 It ain't broke, so don't fix it.  

  

 I had my Lycoming IO-540 "gami-fied" by Don Rivera and it is absolutely running perfectly, and at less fuel flow than anyone ever thought.  I use 9.3 gph, at 21" and 2050 rpm, which is about 52%, and cruise my Harmon Rocket at 188 knots for efficiency.  Push it up to 23"/ 2250rpm, and burn 10.1 at 196 knots.  All validated by Vision Microsystems 1000, and good ole G.P.S.

  

 Can you in your widest dreams, ever save fuel over these numbers, or engine life span, or anything that will pay you back Three Grand?
