The FYI above was to highlight the great allowable variation in engine timing that is not "too far advanced"
The adjustable variables above will shift those little bars around a lot on that round gauge.
But to make the statement implying the LAME has timed the engine wrong is made by an uneducated person on such topic, but happily bags out maintenance staff.
My opinion of the engine monitoring systems and balanced or Gammi injectors is they are great, but not always useful.
* In trouble shooting - they may isolate a cylinder but many times via wiring error be the wrong cylinder.
* They do not in any way shape or form indicate anything other than temperature of a cylinder - not a reason why it is different to others by a small or large amount.
* Extend an engine TBO. They have zero effect on wear on cams and con rod bearings also little to no effect on cylinder wall and valve wear. A top overhaul with new cylinders will give a better break down report for engine extensions than anything else.
But for private ops and on condition engines they can save the owner/s lots on fuel and reduce cylinder related maintenance costs. Just don't tell me the timing was too far advanced unless you can prove it is!
