Okay,
So I recently have been misfiring after running on a solid tune for a month now and I notice that Fuel Status is 8 constantly. Now I read this:
If the Primary O2 sensor fails to respond to the ECU within a reasonable time after the car starts up, the car will go into an error status on the fuel (8). In this state, the ECU will run statically in Open Loop. Most (99.9%) of tunes are not safe to run in Open Loop statically. It is highly advised that if your Primary O2 sensor fails that you replace it as soon as possible and avoid driving the car except to get it to a place to get the sensor replaced.
But.. if the Primary 02 sensor fails.. wouldn't it no longer be reading AFR's completely?
Is there another problem that could cause this Fuel Status 8?

Hope it fixes the problem!
