Hi
I'm running obd1 Hondata with boost and a 4 wire o2 sensor.
After the motor blew up on the dyno when doing the last power run, I put my other motor in but now my car drinks fuel bad, tried changing the o2 sensor didn't work then I unpluged the sensor but got no check light.
Could the closed loop be disabled so the ecu don't reed from the o2 sensor.

Thanks to all.

 

yes you are correct, my car is the same way.

 

yup with hondata u can disable the o2 but u do lose some gas mileage from it
