Hi JJR,
Our EMS systems are compatible with the OEM CHT, Oil Pressure and Oil Temperature probes, and RPM senders that come with the Rotax engines. If those probes are the OEM parts they should work.
The first item you list is "pressure probe". If you are refering to fuel pressure, not oil pressure, then you need to use the fuel pressure probe which we provide. We are not compatible with other fuel pressure probes.
Our CHTs are type J thermocouples. Our EGTs are type K thermocouples. If that's what your CHTs and EGTs are, they will work with the EMS. If they are not these thermocouples they will not be compatible.
The hour meter is built into the EMS.
Additionally, note that our Rotax sensor package includes the following sensors and probes:
2 EGT Probes
Manifold Pressure
Fuel Pressure
Amps Shunt
EGT/CHT Harness
Main Wire Harness
And as mentioned above, we make use of the Rotax OEM:
CHT Probes (2)
Oil Temperature
Oil Pressure
RPM
Like always, the fuel flow sender is optional.
