A V-AFC is only fuctional if you have aftermarket cams and need to adjust your fuel mapping.

The stock VTEC crossover point is optimized for your stock cams. Unless you have swapped out for more aggressive cams, I would leave it alone. People who have installed VTEC timers to engage VTEC lower in their rev range are idiots, unless they have grinded their VTEC lobe to be less aggressive- in which case they're still idiots. When more aggressive cams are installed, the VTEC point needs to be moved up. Stock cams? Stock VTEC timing.

As for air/fuel mapping, this only becomes important late in the game- after FI, nitrous, or those aggressive cams we were talking about. Without these, expect maybe 2-3 horsepower at some points, with losses of 2-3 at other points.

Still worth the $400?
