Hey guys i was playing around with efi live V4 on my mates VX commodore v6
He was complaining about really bad fuel consumption.
So i checked the o2 sensor voltage at idle there seem to be no cross count just stays around the 500mv
See pic below
Also the fuel mode cuts in and out from open loop to closed loop.
Which makes me think the o2 sensor are gone. Coolant Temp checks out also.

Also when i rev the car to 2000rpm it will take its time to start to read normal cross counts.
