ihave a few questions reguarding the safc and fuel curves

1.whats the point of the high and low throttle points
2. i read some where that you should get trims to cancel out?!?! <- what does that mean
3.whats the max desired duty cycle for a injector
4. what are fuel trims in terms of low mid and high and how do i use those for tuning
5. whats the desired o2 value

thanks in advance for all the help
