*edit* I know this isnt related DIRECTLY to ecu tuning, but it has to do with tuning. if a mod wants to move it, please do. thanks
Ive noticed that alot of people always say that its always better to run richer than to run lean. My answer to that was always that in some cases, detonation can come from being too rich. I havent really explained it and didnt feel like it, lol.
but i found a great article on this subject.

This is kinda like a guide as to what afr's you should run for the optimum power output, assuming timing is at its best of course.
This is in lambda, to convert to AFR multiply by 14.7.
Idle - .90-1.0
Cruise - 1-1.05
Overrun - 1.09+ (I believe overrun refers to being in the higher RPM areas with the throttle closed)
Transition (high load, not boosting) - .88-.90
Low/Medium boost - .82-.87
High boost - .80-.85
Dead zones (areas of the table not normally seen) should be reasonable values which follow the contour of the rest of the table.
This is a GUIDELINE. If you were running, say, an air-cooled & turbo Porsche motor you would want much more fuel to help counter the heat.
