Does anyone know about the A'pexi VAFC-II controller or does anyone have one?
Does it help out any?

 

many people have them. on average they're good for ~2hp gain so save your money.

 

i was thinking about getting one too.. i guess not anymore.. haha

 

I had it on my V6 Accord... NO DIFFERENCE. After it got totaled I sold the Apexi II for $175 to a friend. Sale the money for CIA or headers, something that will make a difference.

 

I have one Installed and I like it.
It may/may not help you make more power (I bought the car with), but just for the fact that it allows you to change the VTEC engagement point is a big plus.
I have tested many engagement points and prefer to set mine 600 RPM lower (4200). I find the engine power much more useable at those settings.

 

switching vtec lower gives you better top end but you lose bottom end power. I still have my vtec setting at the stock point which is 4500 I believe.
