I'm having a problem I think dunno. I let the sensor hang in free air and warm up for about an hour as the insutructions say. I turn the knob until it says "cal-" and I let it sit for 3 mins. I turn the ignition off cutting power to the unit, and then I power the ignition on again to check everything operated okay, and the AFX controller still says it's in "cal-" mode. Should it not kick off?
The instructions do not say what to do after adjusting the knob to say "cal" so I'm totally lost at this point. Is this something where I set it to "cal", turn the power off, then put the wbo2 sensor into the exhaust and run the car? Someone mentioned that as soon as the sensor reads the exhaust it will kick out of calibrate mode....
I'm lost, please help!
