How many EGT probes are people running on their motors, all nine cyclinders?
———- Scott, we use one CHT and one EGT probe each on our Model 12’s. We use the EIS system from Grand Rapids Technologies as they have developed an M14P specific unit for us that is set up for 9 cyl, air start pressure etc. Good people too. We did install all nine CHT and nine EGT probes on one Model 12, but it was a pain and really didn’t add much useful info.
