What do these mean.



and what should I set mine up as.



I have s5 high imp 550's.



It's currently at -10.5 but I have no clue what that means.





Thanks.

Are there 4 columns?

They should be all set to 0 I think!

The trims allow you to vary each injector's pulse width individually across the entire range. I've used it on piston engines where the intake would not allow even airflow to each cylinder. To properly set it up you need AFR or EGT readings from each cylinder or rotor. You build your map with the trims zeroed out. And then look to see if one cylinder/rotor is consistently more rich or lean than the other and use the trim to independently vary the pulse width across the board for an even mixture in each cylinder/rotor.
