I am planning on purchasing a chipped ecu from Kenji and was looking to get the V-afc to tune it out. I was wondering though, other than the V-afc being able to adjust vtec crossover, what is the difference between the V-afc and the S-afc in fuel tuning?

 

I believe the only difference is the V-tec controller.

 

Do a search. I'm sure it's been discessed before many times....

 

Just vtec controls.
