From what I can tell from looking at apexi-usa.com, S-AFC allows for air/fuel mapping and V-AFC allows for air/fuel mapping and Vtec engagement control. V-AFC might not give out boost readouts, and other stats of interest to boosted cars, but the features of the V-AFC seem to be more indepth (even if it's only the Vtec remap). Someone who knows the truth, please explain.

S-afc is fuel mapping only V-AFC is the same controller with VTEC controls built in. Same readouts and fuel controls.

 

The V-AFC also has additional tools to compensate fuel between the stock VTEC point and the new one set on the V-AFC.

 

So, from what I can tell, S-AFC has nothing that V-AFC does not have. Just wanted to double-check before going with either. Looks like V-AFC will be the choice.
