Im just starting in on my avionics and I intend to install the GEA 24 engine monitor. It seems the kit came with two egt probes. I already have egts on each cylinder. Are we expected to drill more holes? Is there a way to read out what the Rotax egts read to the Garmin g3X? It seems silly to have redundant egt probes and then to only have two cylinders monitored.
