Hello,
On the EMS-220 I can connect tank 3 on pin 22 and tank 4 on pin 23.
However on the EMS-221 there is no place to connect tank 3 even if the EMS221 on the rotax 912is has almost no wires or sensors connected to it because almost all the information goes via the CAN bus.
I want to know if there is any way to connect tank 3 on a system with an EMS-221.

Thank you,
Filipe
