Default Lemmiwinks CH10: Primary Fuel Tweak. what does it do?

Ch02 : Fuel Tweak (Accel Pump); Increasing Loads
-This channel adjusts a fuel enrichment under load
-Modulates Throttle Response

Ch03 : Fuel Tweak (Accel Pump); Decreasing Loads
-This channel adjusts a fuel enrichment term coming off the gas or decelerating.

Ch10 : Primary Fuel Tweak
Controls fueling on run, ussually change multiplicative fuel trims
- Higher number enrich the mix
- Lower number lean out the mix

most people use Ch2/Ch3 to get their long term fuel trims back to 0. but no one mentions or uses CH10. any ideas the difference between CH10 and 2/3?

Default ah finally found it from google.. details

Primary Fuel Adjustment - This variable alters the injector opening times to allow the injectors to open the necessary amount to meet fuel demands. Tweaking this variable up and down can alter the actual air/fuel ratio of the vehicle.

exerpt from APR's v-tune software. which in essence is the exact same thing as lemmiwinks.
