Do you even know what a V-AFC is? It's an air/fuel controller, hence it's name... VTEC-Air/Fuel Controller. It's a version of the S-AFC, Super-Air/Fuel Controller, that comes pre-set for Honda speed density fuel systems and includes a bonus VTEC controller. This device is used to tune the fuel curve of an individual car
on a dyno.
I've personally seen a seven
wheel horsepower gain by tuning a car's fuel curve with an S-AFC to deal with basic bolt-ons.
The V-AFC/S-AFC is a superior means of fuel correction to a generic chip.
