I'm looking at getting a Carsound / Magnaflow cat.
I'm using an obd2 b18c1 (97 GSR) with an obd1 p72 ecu (95 GSR) in a 95 civic.
My stock 95 civic cat has no O2 sensor in it. A 95 GSR cat has one. A 97 GSR has 2!!
Will I have to use a 1-sensor cat with that ecu to prevent the check engine light from appearing? If so, would I need to wire it into the obd1 p72 ecu?
Also, If I used the sensor-less cat, could I bypass the emissions part of the ecu and avoid a check engine light?
thnx!
