Description

This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 06/03/2026.

Key Technical Capabilities
  • Multi-Cylinder Temperature Scanning: Continuously tracks Exhaust Gas Temperatures (EGT) and Cylinder Head Temperatures (CHT) simultaneously across all six engine cylinders using high-precision Type K thermocouples, displaying both graphical bars and numeric values. 
  • LeanFind Optimization Mode: Features JPI’s proprietary leaning software algorithm to automatically identify the first cylinder to peak during mixture leaning procedures, enabling precise lean-of-peak (LOP) or rich-of-peak (ROP) operation to optimize fuel efficiency.
  • Dynamic Shock Cooling Alerter: Actively monitors the rate of cylinder head temperature drop during descents and power reductions, triggering automatic pilot warnings if thermal stress limits are exceeded. [1]
  • Onboard Flight Data Logging: Features an integrated internal memory module capable of continuous data recording, capturing detailed engine performance parameters for later download via USB interface to track maintenance trends. 
  • Scalable Sensor Architecture: Supports plug-and-play expansions for accessory parameters including Outside Air Temperature (OAT), digital fuel flow transducers, oil temperature/pressure probes, and manifold pressure lines.
