Update* How to pass Chicago emissions (OBD2)
 

Sup guys a while ago i made a thread about trying to pass the OBD2 test and some people were interested to see what happened so heres the update.

The car is a 97 hatch with a JDM b18 motor and a obd1 conversion. Obviously the car cannot pass with the obd1 ecu but i gave it a shot anyways and i failed.
This is my setup to pass the OBD2 test:

USDM oil pump w/ crank sensor
Plugged up a secondary O2s no cat
97 GSR ecu (OBD2a)

this setup on a 96-98 civic with a JDM swap will pass.

I tried to use the 96-98 ex ecu but it threw a code 91 (fuel tank pressure sensor) 96-98 dx's do not have this sensor, i believe 99-00 dx's have the ftp sensor and can use an OBD2b ex ecu. I hope this helps you guys out https://honda-tech.com/forums/images/smilies/emthup.gif and kudos to me cuz i finally beat the "man" and passed without a cat https://honda-tech.com/forums/images...s/emsmilep.gif

they didnt look under my hood. the guy even noticed i had a turbo, he was a younger kid.

Well, you're damn lucky they didn't notice you didn't have a cat. If they had noticed you'd be out a couple grand in fines.

Basically you passed because they trusted what your ECU told them and didn't check your tailpipe emissions. In a year or two when your bumper's all discolored from running without a cat they might wise up and catch you.

You never know when you'll get a guy who actually bothers to do his job to the best of his ability, instead of just count the hours until his shift is over.
