I am going to install V-AFC this weekend.
Is it safe to install V-AFC on S2000?
Also, what rpm should I set it up for V-tech? 5000rpm-5500rpm.
i need some advice ASAP.
Does it avoid the factory warranty?

It will void the warranty and VTEC should be set to 5600 RPM's. This should be tuned on a dyno when installed.

 

I wouldn't do it if I was you ... It's rarely done in Japan on an F20c for sure and I'll rather opt to change the whole ECU rather than just install the V-AFC thing. It's not that big of a deal changing the RPMs or the fuel controls, in my opinion.

 

Actually the V-AFC is the best 'bang for the buck' mod that I have seen to date. You can lower VTEC to 5600 RPM's and adjust fuel where needed. After mine was installed the VTEC transition was much smoother and I gained a fair amount especially in the high RPM range.
