I guess this question is for David Ribbe, and anyone else that would know:

How noisy is the Sophia ECU (JetCat) and what precautions should I take with installing it. I have noticed that the ECU wiring came with filters installed, but what other precautions should I take to avoid RF noise? Any help would be appreciated.

I keep all of my High Power ECU Components in the nose of the aircraft (ECU, Fuel Pump, Battery)
I use chokes on the pump, battery, throttle, and aux leads.
I keep the Leads as short as practical.
I also 'twist' the Leads as practical.

I make sure the fuel pump has ceramic disc capacitors installed.... + to can, - to can, and + to minus. (Cuts brush noise... (Some motors may have some installed internally)

I mount the Rx at least 10" behind the ECU... and run the antenna aft. (or whip 'up').

This has worked well for almost 6 years.
(The ECU is Jettronic (Jetcad) V2.x)

FWIW, I ussally fly on 29, 31, or 33
