I have a SKyleader 200 with Rotax 912 fitted and with factory fitted EMS. At present the MOF/LOF readout is displayed disabled with a red cross over it and marked UND. Is this correct ? I could assume that as the 912 has a carb withautomatic mixture control that this is not a possible reading anyhow. If so can I disable this function. Any help gratefully accepted. PS I only have two EGT sensors fitted
