What voltage source did you use for the trim potentiometers? If you used 12V, this could damage the EMS.
Your trim servos have three wires- ground, power, and signal. It's important to not hook the power side to anything above 5V, since the GP inputs on the EMS can't handle more than 5V. Just checking!
We do hope to have firmware for you in the future that will work. For now, if you really wanted to, you could define two of those inputs as fuel levels and they will move with the trim.
