Australian M20K Owner Posted August 30, 2025 Report Posted August 30, 2025 I just flew 25 hours over 2 weeks. My EDM 830 started to alarm "DIF" at low RPM (i.e. not in cruise) with #6 cylinder EGT being the hottest. I am thinking either a manifold inlet leak or an injector issue. Anyone else had a similar experience? The aircraft had it's 50 hourly last week and compressions were fine.
natdm Posted September 1, 2025 Report Posted September 1, 2025 That’s weird for sure. Mines always the lowest by a relatively substantial amount. The diff between highest and lowest on mine can be 47f, with #6 the lowest at 316.
PeteMc Posted September 1, 2025 Report Posted September 1, 2025 Typically #5 is the hotest on the TSIO-360 due to the air scoop blocking a good amount of the airflow. So maybe a bad probe?
