Rotax 912 iS (Electronic Control Unit)
Table 45 below is the suggested sensor connections for a Rotax 912 iS engine connected to an
SV-EMS-221 EMS module. Note that the Rotax 912 iS engine does not utilize thermocouple
sensors to monitor CHT and EGT temperatures on the SV-EMS-221 EMS module, thus there is
no connection to the D25F connector on the SV-EMS-221.
