me and my friend just installed the vtec controller onto my 91 civic si w/turbo b16a1 swap. the ecu is an Pr3, the problem is why isn't it able to lean or rich my 440cc injectors. we double checked the wires as well?? we tried setting the vtec at 4500rpm and it works but i don't know why it wouldn't work for my fuel...any opions??

 

Uh...cause the ECU think you have 240 injectors

 

What kind of controller is it? Does it have fuel adjustments on it? Did it wire into the MAP line at all?

 

evem if they are as big as 440s, you should still be able to lean it out, sounds like you dont have the MAP sensor tapped
