Which periphery is the rear o2 heater check? My monitors are labeled as follows-
heated 02- passed
o2- not ready
catalyst- passed
I have the rear o2 enabled under mods. My periphery0 hex is 54DA. My periphery00 hex is 5650.
heated 02- passed
o2- not ready
catalyst- passed

The rear O2 should pass with flying colors as long as the rear O2 heater check periphery bit has not been disabled.
Very strange about front O2 not showing readiness. There is no connection between the JDM MAP mods and the front O2 sensor. With the discussion we are having by PM, I'm kinda wondering if perhaps the ROM that you're using is slightly buggered. I had it happen to me once before. The car would run pretty normal except when I got on it, and then it wouldn't go near the boost target. I reflashed with a clean ROM, and all was good.

According to this info your rear passed - cause rear O2 is catalyst. The O2 that is not ready is your front O2. The first check you have is O2 heater (not heated O2)...

Interesting. The front o2 is new because wwhen I installed a new 02 sensor housing the stocker wouldn't come out. I noticed that the new housing relocated the sensor to a different location. It's not sticking out the front of the car but more toward the belt side of the engine. Could this be the problem?

You need to do at least half an hour or more part throttle driving, the same highway cruising, and about 10 mins worth of total idling. I typically drive the car 100+ miles before making changes. They will drift one way on startup, another when warm, and drift some more when weather changes. Find the best average.
