The engine monitor is interesting. It is the Insight G4 which is a 3.125" size – like my rebuilt-bigger EDM700 – and it does RPM, MP, Fuel Flow, Fuel Totalization, OAT, EGT, CHT, TIT, Oil Press, Oil Temp, Prop Balance, G-Force, TO Performance, HP%, Turbulence, and Data Logging. When we discussed it here, the company told me it cannot do oil temp.
