The only diffrence between the SAFC1 and the SAFC2 is the the rpm increrments that you can change, 200 on the SAFC2 and 500 on the SAFC1 right? Your still cool to run open atmosphere BOV on a hot wire system right?

 

Amount of rpm set points and the button/dial change. I also believe there is a voltage input or something.

 

So is it really worth going for the safc II? Or would safc-I be suitable for most?

 

Depends on the price I would imagine. The second gives more flexibility. You should just chip your ECU.

 

Damn dude, you sure went word for word on that question.
