One additional thing to know about the ECCI pedals is that they do require to be 'grounded'....so if your cockpit setup is close to an electrical outlet, that'll do fine!
Why? Because the pedals are made out of metal and thus will create static electricity.
I've also noticed a few times when I moved the pedals and forgot to hookup the ground cable again, that during game-play, the gas pedal stops working for a few quick seconds. Once the ground has been re-connected, the problem goes away.
Food for thought! ;-)
