Alright I have a 97 civic dx hatch back. Though the problem is that the dx has two o2 sensors. One before the cat and one after it. Well i temporarily bought headers and exhaust till i get my turbo. THe problem is the headers only can have one o2 sensor. Thus the computer will mess up and also i'll throw a cel everytime. I was to fix this by converting my computer to obd1 but the thing is they don't have chipped obd1 ecus for the dx. I don't need the vtec ecu. I still need it chipped and everything for when i have my turbo. Any suggestions on how to fix these problems. Please help me out. Thanks.

 

Also my turbo will only have one 02 sensor.

 

Your best bet is to run an O2 simulator such as this one.

 

any other suggestions?

 

add another o2 bung.

 

bump...

 

add another 02 bung hole.... you can buy the nut at a hardware store just use a spark plug as a reference..

Drill a hole big enough and weld the nut on and plug your o2 sensor in.
