B20 into ek O2 sensor
Im getting ready for my first start up on my swap, I still have my O2 sensor on my downpipe and my secondary one( on the mid piping towards muffler*forgot whats it called*) Do I have to run those sensors when running a chipped obd1 ecu ? I have a chipped p06 ( waiting on my honata s300 )

Re: B20 into ek O2 sensor
With an OBD-1 ECU, you will need to run the front (primary) O2 sensor but the rear O2 sensor is not needed. If you cannot get the primary O2 sensor somewhere in the exhaust stream, you could delete the sensor in the program on the chip and run "open loop"... not ideal, but it works.
