First, I have about 120 degree dfference between my front and my rear rotor via the EGT sensor. The rear one (near the prop) is running hotter. This seems to be one of those thngs I use to know...and what should do to remedy, but I can't wrap my head around it now.
The EC 2 has a mode for balancing the mixture between the rotors.
You need to determine which rotor peaks first, with regards to EGT.
Set the throttle above staging and making power (running), then lean slowly and watch one then the other reach their own peak EGT's then start back down.
The first one to peak is leaner. The second one is richer.
lean the rich one or richen the lean one to make them match as closely as possible. This will also smooth the engine further as both rotors will then be making uniform power between the two rotors.
The EC2 manual should have a procedure on how to set the mixture balance (or maybe its in these other replies ive not looked at yet)..
