Does anyone have the ecm pinouts or any kind of directions on how to install the VAFC on the S2000?

Thanks

Try this.

 

that's the one .... you can also ref Apexi's WH-4 diagram off their website

 

thanks alot guys. i appreciate the help............

 

Ok I took a long time to install this but it was definitly worth it. Such tight/alkward positions you gotta get into. I was able to put my kick panel back in without much work. I had the V-AFC harness but it was just to big to fit back there.

Ok to go along with the picture above I have in-car color codes and instrucitons. Page 11 of the install PDF is helpful as well.

RPM- Signal goes to the GREEN on the V-AFC- In car Blue- silver dots(just tap in)

IGP- Tie RED AND ORANGE together and tap into Yellow/Black w/ silver dots.

Pressure Signal- Cut Green/Red in car. Yellow on V-AFC to ECU and White goes to the Car side.

VTM- Cut in car Blue(black dot or stripe maybe) and connect BLUE on V-AFC to ECU. Cap other end off coming from the car.

Ground- Tap in BLACK on V-AFC and BROWN on V-AFC though put BROWN closer to ECU.

VTEC- In car color code Yellow/green(maybe dotted too) cut that put PINK to the car side and PURPLE to ECU side.

TPS- Red/White in car color- tap in GREY on V-AFC.

I believe these are all correct as my car works correctly and all readings I got on the sensor check was what they should be.

I ended up using some male/female plastic covered connectors to hook up the wires that I had to CUT. I did them so if I were to take out the V-AFC I could just connect them back together in 5 seconds and just cut off the wires to those that I had just tapped into the factory wiring. I did not use SCOTCH LOCKS or "chicklets" as my installer calls them because of their perpensity to F-UP in no time flat.

Good luck all.

If there are changes/corrections please let me know so I can edit this message.

 

what does the vafc do? does it change vtec engagement? is it worth it? also, how much does it cost? thanks

 

It is a piggy back system that can make changes to the air and fuel. It also modifies the vtec engagement.

Costs around $300 and it is worth it if dyno tuned.

 

I'd hook it up in a way so that it doesn't interfere w/ the VTEC and only use it for A/F adjustments if at all.....
