For Your Safe Flight ............................................. Page 33
Leaning Lean Of Peak (LOP) Detection: Note: This mode should only be
used when your engine is equipped with balanced fuel injectors or you
have a DIF value of around 80 degrees. When using the Lean of Peak
mode, you lean until all EGTs decrease slightly below their respective
peaks. The EDM has automatic peak detection and will sequentially
indicate leaning progress. When the first EGT peaks, the word LEANEST
appears and the cylinder I.D. box highlights the cylinder number. Each
column successively drops as leaning continues. When the last column
drops (last EGT peaks), RICHEST appears and its respective column
flashes momentarily. The last EGT to peak is the one you will use when
setting the final mixture.
Finalizing the Lean Of Peak Mixture: The Scanner® Information Area
displays the degrees below peak for the last (or richest) EGT to peak,
giving you precise information necessary in setting the final mixture.
Adjust the mixture to achieve the desired value below peak (using the
digital EGT readout) or before engine roughness occurs. Caution: do not
lean to the point where the engine runs rough. Note: the peak EGT value
encountered during leaning can be recalled by holding the PEAK button.
Do not exit until finished or all values will be lost. Tapping STEP exits the
lean find mode and automatic scanning resumes.
