I have a 98 civic that in NY has to be plugged into the computer when inspection time rolls around.. My question is if i swap an obd1 motor and run a jumper from obd1 to obd2 nd put my ecu back in wen inspection time comes will i throw any codes? thanks

 

OBD2 engines have a knock sensor. and i think an extra o2 ? not 100% on the o2 so yes you will throw a knock sensor cel

 

yeah i was hoping that only jdm motors didnt have knock sensors..oh well thanks for the help
