I doubt that you've done any serious damage to the PCM which would cause it to self destruct or anything like that.

As much as I favor doing some of the generic stuff, you would honestly be better off getting an OEM O2 sensor.

Is the sensor you purchase a wide band or a narrow band? The RX8's primary O2 is a wideband sensor. You might be better off getting one from the dealership which would be plug and play. If it's a generic narrow band the PCM is going to have a fit.

In either case, when you get a new sensor hooked up just be sure to do a PCM reset. Disconnect the battery, press the brake pedal for 10 to 15 seconds to totally drain any power and let the car sit for maybe an hour to reset all your fuel trims that would have been created from the faulty sensor.

With that and a new sensor you should be right as rain!
