Full EM5 system on an IO375. During low power or idle descents 3 of the 4 egts will drop below 700ish degrees. Cylinder 4 stays up around 1150-1200. All 4 egts read within 50 degrees at cruise and climb and respond correctly during normal ops. There's always a some "lean popping" from the exhaust during extremely low power descents, but if this popping was coming only from cylinder 4, would it be enough to keep that egt higher than the rest?
Because installation varies absolute egt values, peak egt is normally 1550ish. Normal ROP/LOP range is 1350-1400, and very LOP is 1250-1300 range.
