I got my nistune software and consult cable etc few weeks ago, now when I go to consult gauges with the car running, it show's u rpm, afm voltages, o2 sensor etc etc
I noticed that one of my o2 sensors is showing 0.08ish at idle while the other is showing 2.50ish
I disconnected the back o2 sensor nothing changed, plugged that one back in and unplugged the front one and both showed 0v now
Why is it when the front one is disconnected both go offline according to the consult gauges ?
It's almost like the front one is controlling both? But ones voltage is mega high?
What the hell is causing this
