I do have a S-AFC, but I also have the wiring diag. for a V-AFC.... The electrical diagrams are complients of Helms =)
It is the same that the Honda Dealerships around here use....
V-AFC has 2 functions:
Control the fuel flow to the injectors
Control the time at which the VTEC solenoid valve kicks in

You can't put a VTEC Controller on our cars but there is a substitute.
Apex i Super-AFC. We do not a VTEC Motor but with the S-AFC we can adjust our
fuel maps on a hi and low thottle scale... You can also set where you want to difference between
hi and low thottle settings.
I have noticed slight increases on my LX.. I think that is works the best when you are pumping NOS through a Venom Kit.

Hey boosted, I follow everything you said, about the installation, and I got it on, and the pressure, throttle possition are working but no rpm signal and of course, vtec not working because it works with rpm's. I think you said, the green wire of the vafc was supposed to be connected to the baby blue one, I wonder if you are getting the cables from the ecu or underneath the carpet, because in the ecu there is a baby blue wire a kind of blue-green wire (very similar to the baby blue one) and the same blue-green with a red line. I hooked it up to the baby blue one but no rpm signal no were, so whe I pass 4000 rpm's check engine light comes on and It wouldn't pass 4000 rpms, what I did was that I left the rpm cable (green) disconnected and I hooked the vtec wire as it was, everything is normal but I can only see the pressure and the throttle settings. What do you think,!!!!!

Here goes. I have took my digital camera and took pics out of the Honda book so that you can see exactly the (3) different locations of the Tach Wire AKA TDC Sensor.....
Since the pics are so big, I am just going to link them....

jiimy, did you wire it up w/ boosteds instructions just fine, or is there anything you can add?
also how does it feel? good? did you turn it way up to like 5500 yet [IMG]i/expressions/face-icon-small-smile.gif[/IMG][IMG]i/expressions/face-icon-small-smile.gif[/IMG][IMG]i/expressions/face-icon-small-smile.gif[/IMG]
I hooked it up with boosted intructions, the hardest part was to find the RPM signal wire, but he send a couple of pictures, there's one of them that I used, (the one showing where the tach test point was), what I did was, I used a multimeter to check continuity in that test point and inside the car, by the ECU, also I never ran wires through the firewall, he just gave me that idea and I used the multimeter to find the map and VTEC sensor wires in the sensors itself, checked continuity inside for each cable. But you can use Boosted intructions and you will get it right for sure, he's got the diagram. My is running fine, you can adjust VTEC and fuel but the system is very complex, I am taking my car to a shop to get it tunned and so they show me how to use this thing wright. As soon as I get it tunned, I'll let you all know for sure. hope I answer your question!
