good morning people!

i was wondering if i could use the ApexiV-AFC on my Integra LS even though i dont hav VTEC, and if i can, would this be a wise choice?

S-AFC maybe? wut's the difference?

well safc stands for super air fuel contreoller while the one with the the vtec is v-afc

so you'd need the safc, well what are your mods cause you might not even need that.

if all you are trying to do is make an adjustment to the a/f then you could get one of the chips as that changes those maps in the ECU for those...

Just w/ those 2 units it's a bit of $$,Especially for things you don't need or use right now, but if you are going to do like a Vtec head swap or going turbo or something the Apexi pieces would be nice...

well i'm going to turbo it and i dont want a hondata chip right now so which way should i go for fuel management? i mean is there a diff. in the super and the vtec apexi units besides the vtec... can i use the vtec one even if i dont hav vtec?..

here's my fuel stuff right now:

-450cc DSM injectors
-resistor box
-Walbro 255 fuel pump
-fuel pressure regulator

then of course wutevr Apexi unit i decide on....

will that be all i need for the fuel part of my turbo?.. i'll be running low boost 6-7 psi for the time being...

It will work. The wiring is basically the same......but why get the VAFC? Stick with the SAFC. It will be a wiser choice. You can also do a "blue wire" mod with it. You cant do that on the VAFC.

If you dont already know what a blue wire mod is, the SAFC has an extra function that Honda ECu cannot provide which is why the blue wire on the SAFC is not used. However, you can use that blue wire and tap it into your primary O2 sensor wire to read the voltage output of the O2 sensor. Every voltage reading equates to how much exhaust gas flow you are putting out. I cant remember exactly what the equation is at the moment. This will give you a ballpark idea if you're running rich or lean. Sort of an A/F ratio gauge... but in numbers. Useful for tuners. Goodluck
