I recently purchased a '96 Integra w/ a B16A2 swap. It is currently running a Hondata S100 obd1 ecu. The seller was nice enough to send me away with a 99-00 Civic Si OBD2b ecu. I am a full on noob and want to know if simply removing the Hondata S100 unit from underneath my glove box and replacing it with the 99-00 Civic Si unit will suffice for safe travel to the DMV and also passing the test?

My next question is...

Some people have mentioned to me that in Wisconsin they recently began only testing the ECU and not actual emissions from the exhaust. If this is true, would I be ok with my catless straight pipe? If I try and that doesn't fly, can I come back the next day with a cat no harm, no foul? Or should I just get the cat first thing tomorrow morning? I hate the raspy sound that is allegedly because it is catless so I may go with a cat regardless.

I did search but it seems like no one out there was as ignorant as I about this to make a thread. Either that or I didn't search using the right parameters. Thanks in advance!
