Michael,
I am setting up my single rotary engine with my own 44mm slide carb. This will be on a test stand to iron out any bugs.
There are simpler ECU's but Tracy's have the lean function which we all need, however like yourself I'm not comfortable with the setting up of an all electric system - to me it just seems way to complicated for what it is, and too may things to go wrong. Like many of us I am not much on reading manuals/instructions, to me it's always the last resort for anything. For me anything with a menu is a headache.
 
The plugs up is ok, I looked at that myself but didn't want the complexity of making the sump system, however it would be very useful with Renesis , because of the flooding issues, and maybe the 16X.

Ed:

 

Yes, I agree with that assessment. The reason I am making that choice is that at my current level of knowledge I am better prepared to deal with the problems of tuning and operating a carburetor than those of developing a functioning FI system and am reasonably certain I can make it work and am also willing to live with the limitations of a carburetor. As I progress this may change and I may be better equipped to handle the complexity of the FI induction. Right now I am aiming for a purely gravity fed carb not dependent on electrics at all.

 

In fact I was considering switching to a plugs up set up to make a gravity fed carb even more convenient. Beyond the new "side saddle" oil sump set up what other changes were necessary for you to get the engine to operate correctly on its side? did you need to modify any of the internal plumbing/oil galleries on the engine to cope with the 90 deg turn?

 

I will touch base with Oly for his input on the carb matter.

Also, do not think that choosing the carburetor is going to eliminate potential problems, you’re simply swapping one set for another.  While carburetor (like the EC2) will certainly work, I encourage you to check with my friend Oly Olson who can reveal some of those associated challenges.
