What are some of your all's settings for your vafc II . I Have a 99 civic si with the standard b16a2 motor i Have Full exaust. mugen thermo,greddy header,Skunk 2 intake manifold and a vafc II.Im asking what are some of your al'sl air fuel ratio's I need to know what level is best to set it at. If you cant understand this post its because im really tired and stuff. So sorry if I waste my time.

 

Take your car to the nearest dyno and have them tune it with a wideband o2.

You'll do more damage than good ******* around with the settings yourself.

 

yes.

dont tune it yourself without a dyno and a wideband.
dont use anyone else's settings. each engine is completley diffrent and will have completley diffrent tuning setups.
