O2 sensors with Power FC

[Yorl8]

Hi, just a quick question. I've just installed a Power FC L on my Evo 8 260, and I'd like to know if any of you has tried to remove the rear O2 sensor and bolt a the wideband sensor (AEM) instead. Any problem performancewise? Also, will the CEL light go on?
Thanks

youll need a narrowband emulator as the PFC expects the 02 sensor to be in the range of the stock one which is probably 0 to 1v
you cant just feed it a 0v to 5v wideband it wont work - the check light will come and youll have crap fuel economy - most 02 sensors can get an optional emulator for narrowband which will take the 5v and remap it to 0v to 1v output for the PFC or any other stock ecu
