I just found this, easy explanation, even I can understand.
Lean mixtures burn faster than rich mixtures and they tend to produce more heat. Richer mixture needs more timing to completely burn and they tend to produce less heat. Too rich will cause knock, too lean with too much timing will cause knock. 0.85-0.86 Lambda seems to make the most power on the LNF so find the appropriate amount of timing for the fuel you are using and mods.
