PRA Kpro in JDM CTR

[bajantuner]

I have a 04 JDM ep3 type r which came with a PRD ecu my friend was selling his Kpro in the Euro ECU PRA so i bought it and installed it in my car. My question is since my car has a oem wideband and the PRA ecu cant read wideband i disabled the O2 sensors and used my AEM Wideband that is installed in the car to tune and keep an eye on AF in open loop, the car has no codes and runs well, with a good tune is that safe? are there any recomendations running this config?

As long as it is properly tuned it should be ok.
