I have a B20 LS and i noticed the car has no O2 sensor. Where it should be there is a plug in the exhaust, now the car i believe has a obd1 conversion harness but shouldn't it have an o2 sensor regardless?
It's an OBD1 Honda ECU that has been chipped. The map on that chip could literally be anything.Any ideas
How about on this ECU can any one ID it?
