The Burger DP fix will NOT interfere with the OBDII readiness tests. It is an O2 sensor modifier and not an O2 sensor simulator. The difference is:
O2 sensor simulator= No O2 sensor actually present. Device mimics an O2 sensor.
O2 sensor modifier = O2 sensor still present, but signal is modified so the ECU does not throw codes.
Think of it as the difference between a piggy back vs. full stand alone.
