i recently swapped a jdm gsr into my 95 civ dx . it runs awesome but i am only gettin like a little less then 200 miles to my tank. I know im runnin real rich cuz i can smell some gas when i put my hand by the exhaust. What can i do??

 

What kinda of ECU are you running? Is it chipped out? If it's chipped out that's probaly your problem. Also check your fuel pressure. Do you have everything hooked up right (emissions crap). Also how old is your o2 sensor. I beleive civic's have smaller gas tanks then integras so you should get less to a tank then a integra. <- Dont Quote me on that one cuase im not positive but i do remember spending more on gas on my GSR then in my Hatch.

 

Im pretty sure your Civic tank is a tad smaller than an integras. You can however swap in an integra tank if you felt so inclined. Yea, what ECU are you using to run this? And what about your emissions equipment?

 

I HAVE SAME PROBLEM I HAVE A B16 SIR 2 WITH A CHIPPED P30

 

The ecu is the stock one , and the exhuast is a greddy evo 2 with a hollowed out cat. The gas mileage is wierd though because i remember getting almost 300-350 miles to my tank in my jdm b16 in my last civic. Is this normal or becuz of the tank size difference? Also the o2 sensor is the one that came with the swap.again HELP ME

 

SUGGESTIONS???

pull your o2 and see how bad it is
get a FPR

 

Have you done a tune-up?

Have you replaced your O2 sensor with an OEM Denso unit?

Most people complain when hollowing out their catalytic converter in terms of gas mileage depletion.
