i got a 97 ex civic and it is runnin rich. i got a obx fuel rail and regulator. I also got a VACF. how would go abotu adjusting it to lean out the mixture. also my check engine light will come on at low speeds, could the rich mixture be affecting this. o and also have a chiped ecu.

 

So basically you have a stock engine that you are dumping a ton of extra fuel into? Or do you have any other mods besides just an chipped ecu, fpr and VAFC?

 

all of the engine mods i have are as followed.
skunk 2 intake manifold
obx fuel rail
obx fuel pressure regulator
VAFC
Chipped P28
Apexi N1 cat back exhaust
DC sports headers
Iceman intake
Nology hotwires

 

just get a fuel pressure gauge and set your fuel pressure to STOCK. then ZERO out your vafc until you get some decent mods and get it tuned.

exactly we had to do all that stuff on a 93 LS...it was fun

 

i was going to look for a shop near me to dyno/tune it for me. thanks for the info. i am going to change out the fuel regulator and rail. it was on it when i got it.
