Unless the sensors are different (which I HIGHLY doubt. As far as I know only the oil sensors are different/incompatible) and you used the JDM sensors instead of your old USDM sensors OR the ECU is damaged (in which case any ECU swap will probably correct the problem) then the JDM ECU isn't going to change a thing.
I suppose that a severe knock may cause a code 52 as well if the knock is so bad that the ECU thinks the sensor must be crazy. So you've replaced the old wiring with new wiring or did you just put new pins on the old wiring? The old wiring has been found to be the most common failure point in this circuit.
