Emissions and o2 simulators ect.

[infamousdiz]

Anyone ever beat Emissions, the readiness (Missing cats) with o2 simulators or OBD ll simulator....you know, not that I condone this behavior it would strictly be for Off-road use.

Yes. They work to some degree, though not 100% effective. I'd say better than 80%-90%. I'm talking the spacers that move the O2 sensor out of the direct exhaust path.

It sounded more like the OP wanted to know for his track ONLY dedicated use in Mexico on his private road.... if he can get back all his timing by electronically getting the car to reach readiness for the O2 reading? I'm not aware of a DPFix for the X5 yet?
