Tuning My AFC to work with my 550's

[xXEclipse]

I have a 1998 GSX With a 1G Swap, 2G Head.. I have 550 Injectors but theyre dumping too much fuel. I think (correct me if im wrong) that the airflow menu is what i need to change? These Are the current settings


1K 2K 3K 4K 5K 6K 7K 8K
-22 -22 -22 -23 -23 -23 -23 -23 = High

-20 -20 -20 -20 -20 -20 -20 -20 = Low


I dont know much someone please help tell me how to tune it to what i need, and also what does hi throttle low throttle mean??

I have stock turbo. Thanks in advanced

Lets say you set the hi-point @ 70%.
-That means @ 70% throttle the AFC will use your hi throttle map.

Lets say you set the lo-point @ 30% throttle.
-That means @ 30% throttle the AFC will use your low throttle map.

If the TPS reads 50%, the AFC compensates and uses the averages of the hi and low map percentages (aka if 4k rpm is -10% Lo, and 4k rpm Hi is +10% the AFC would not add fuel @ 4000RPM @ 50%).

Did I make this understandable?

NOTE: GET A WIDEBAND!!

Sometimes a quick google search can help out as well, thats how i found the guide below. *Dont believe everything you read though, and def. invest in a wideband, possibly a datalogger too! Good luck and adjust in small increments that way you don't grenade anything.

Exactly what they said and based on what your afc says...you either add or take out fuel.
