You can do this if you use thermocouples for the CHT's, such as spark plug ring thermocouples. You can't use the resistive CHT's because we don't have enough GP inputs on the EMS.
We have 3 GP inputs. To these you would wire the coolant temp, coolant pressure, and OAT.
The MAP has a dedicated input on the EMS.
You'd run two CHT thermocouples to the dedicated CHT inputs.
You'd run 4 EGT thermocouples to the dedicated EGT inputs.
Be aware that on a Rotax, coolant temp is basically CHT, and few people run both.
To see how to wire all of this, please read our install manual, which will cover all of the wiring.
