im getting so cunfused with the whole air/fuel set ups, especially the fuel. this is newbie stuff but i got to get it straight. If i get aem cold air, Dc Sports twin Canister exhaust, DC JDM header, Skunk2 intake manifold, 01 itr cams, Spoon cam gears, Spoon valvetrain(springs, retainers), ignition, ok so if i have all of that, i am going to need do change my air/fuel. with cams i have heard it is good to get a FPR, do i also need a V-afc, or ecu upgrade? can i use both of those, becaue my computer will be maping out one thing then ill be changing it with the v-afc? then Fuel rail? i do not really understand how to regulate the correct amount of fuel, can anyone please explain to me what mods i can use together and how it will work? or the best mods for this set up i have told above? thanks alot, sorry for all the writing but im still learning and this is what ive been stuck on for awhile, thanks

 

a FPR would be good along with a VAFC or even better a hondata.

 

Don't count on us to figure this out...get a A&F meter..and check it yourself

no harm intended

 

If you really want a good setup to vary ur air/fuel ratio then go with Hondata.
