In the middle of a swap right now and can't decide which O2 sensor I need to use. Little help please? My logic seems to think I need to use the JDM O2 sensor from the DET.

I would think you should be able to use either one.

Use the JDM O2 sensor, it sends slightly different voltages than the USDM.

Yep use the JDM with the JDM ecu. I remember the SCC issue regarding this.

I'm using the JDM one with the JDM ECU.

I used my W10 Avenir O2 sensor with my stock ECU, SAFC and USDM SR20DE engine and it ran fine, my gas milage went up considerably but that was probably due to teh old one being bad.
Crusing around town and steady throttle was always aproximately 14.5-14.7 A/F ratio and WOT was approximately 13.4-13.7 but I leaned it out a bit with the SAFC. Remeber these are not safe A/F ratios for a turbo car, this was my NA SR20DE and it ran strong to redline.
