Any info would be great, Thanks!

 

Since you using Hondata S300, then no, you don't need your factory O2. You can just put your wideband in the same bung and configure the Hondata to disable the factory O2 heater and to use your wideband for closed loop instead of your narrow band. Just make sure to hook your wideband into your ECU. With the AEM that would be the white wire coming off of the wideband.

 

Great info thanks alot!
