Ok so i've just fitted a DC 4-1 header on my '94 civic eg hatch B16a2 (I already have a full mongoose exhaust system and cat bypass pipe, plugs and leads and induction kit) and a quick dyno shows the fueling/air ratio is all to cock so because i'm going to want one anyways i've just ordered a apexi VAFC2 (http://www.apexi-usa.com/product_ele...=201&pageNum=1) and now my questions are:-
1*Is my car a OBD1
2*How do i wire it in, and has any one got instructions or pics/diagrams of how to wire in to which ever OBD? it is??
3*Can someone explain how to set it up? and what A/F ratio i should be looking for? Will i need a dyno to tune it?
4*Will i notice a big differance when the air/fuel ratio is sorted?
P.S my engine is stock apart from whats listed above, and i have the standard ECU which is not 'chipped etc etc' (p30 is it?)

Thanks for any help
