ok, my bro in law has a 94 GSR w/a jdm itr motor w/s2s2 cams and ef1 valvetrain and a jdm dc 4-1 header and jun ecu w/9.6k redline and vafc2.

Where should we set the vtec x-over and the cam gears before we start tuning the vafc2?

Thanks.

hope you have a wideband as well right? you would need a dyno to actually see where you are getting the gains and what it should be set to, anything else is just guess work and butt dyno experiences. why dont u actually search for dyno graphs for people with those cams and make an educated guess on your own?
