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

your car should be obd1, you need to go on apexi's website or PM me for the wiring diagram and Manual, its really easy to set up and yes you will have to dyno it again to tune it accurately.

 

cool, will i not beable to tune it by getting the the A/F ratio as close as poss to what someone recomends? it does show the A/F at each rpm on the display doesnt it?
Also ive looked at the instructions diagram on the apexi website but it says that is for the 01+ civic EX, will it still be the same fitting wise? thanks

 

Does anyone have a VAFC2 or know how to tune one??? If you do plz HELP!!!
Also if any1 can answer any of the above q's not already answered i would really appreciate it!!! thanks, ste

 

Ive got my VAFC2 and fitted it, it was really easy and took an hour to solder and heat shrink it in.
As for setting up its really easy, this website gives loads of info in the technical area www.g-motorsports.com. Its more just a game of just trying differant settings and seeing whats better.
