LeanAssist 1.2 is out

The 1.2 1.3 version of LeanAssist features a completely new UI which resembles the Engine Digital Management System 800 by JP Instruments.

  • Lean Find Modes accurately modeled for both normal (rich-of-peak) and lean-of-peak leaning.
  • Various other display mode accurately modeled.
  • "Cheat" mode for automatic leaning refined from version 1.1.

LeanAssist, a plugin for flying recips in X-Plane

Did you ever wonder how to lean your engine properly? How to get the maximum power out of it, when in climb? Or howto squeeze the last NM of range out of your fuel on board?

LeanAssist is a small plugin that helps you with leaning the engine. While you lean, it detects peak EGT and can then guide you to either best power or best economy mixture.

LeanAssist works with all airplanes having a fuel-injected, normally aspirated piston engine. As opposed to real-life,  in X-Plane all engines have perfect mixture distribution, so you can all run them lean-of-peak.

To install LeanAssist, simply unzip to your X-Plane main folder. To finish installation, you have to assign a key command or a joystick button in X-Plane. This is explained in the video.

To use lean assist, press the assigned key or joystick button and start leaning the engine slowly. A small screen overlay will appear, reading "looking for peak". Lean slowly until the indication changes to "Peak detected".

  • For best power mixture, enrich again. The indication will display the ROP EGT delta. At 70°F ROP, the display will signal "best power". Stop enriching. The indication will disappear after a few seconds.
  • For best economy mixture, lean further. The indication will display the LOP EGT delta. At 50°F LOP, the display will signal "best economy". Stop leaning. The indication will disappear after a few seconds.
