vafc question very good ? for people and such
 

if i got a vafc safc watever the vtec one is .. im just wonder u scale the maps for the injectors right but boost kicks in at differnt times so wouldnt it be running rich or lean if u scale it for boost at 3000 rpm but then your not boosting at 3000 cuz u are going on the throttle easy... how does it work or am i right?

Re: vafc question very good ? for people and such
 

you're using a VAFC which means the ECU is still running closed loop.

which also mean that the narrowband o2 is still correcting AFR's

so the vafc only programs it when im boosting.. if i got a wideband and 450s with vafc would it be pretty easy to tune or not?

no

just get a chipped ecu and then worry about tuning. there really is no way to adjust the vafc for only when your in boost.
