Ok guys.
The o2 Sensors did come back on to READY STATUS!
1. Also if you have the ADMINTUNE, set it to ' ECONOMY' mode.
2. Make sure you have HIGH FLOW CATS or some type of CATS as my emissions station checked here in Atlanta.
3. Do the below drive cycle.
4. Get an OBD Code tester with Emissions ready function or if you have ECUTEK, get the mobile app and click on OBD READINESS. Super helpful tool and did not know it was there as the emissions guy only told me it was 'NOt READY' and would not tell me why or what was not ready.
What I did to get it come on:
1. Drove over 160 miles total and had to do this over a weeks time due to time and work.

Pre-Conditioning Requirements:
Ensure the Check Engine Light is not on.
Gas tank fuel level must be between 15% and 85% during the drive cycle.
Engine temperature requirement is between 68 and 86 degrees F prior to drive cycle start.
START HERE - The Drive Trace:
A. Start your Nissan 370z and idle engine until coolant temperature reaches 160F (until normal operating temperature is reached).
B. With the engine warm and using a timer (for precision), idle the engine for an additional 1 1/2 minutes.
C. Begin driving. Accelerate smoothly to 56 mph with the transmission in Drive (standard power mode and transmission in auto mode) then release gas pedal and coast for 10 seconds.
D. Accelerate again to 56 mph and maintain speed for at least 10 minutes. Use smooth and quick acceleration and maintain speed as constant as possible.
E. Stop and idle your Nissan 370z for 10 seconds.
F. Accelerate to 25 mph in 10 seconds and hold gas pedal steady for 20 seconds. Use smooth and quick acceleration and maintain speed as constant as possible.
G. Repeat steps E and F eight (8) times. Decelerate (coast down) to 15 mph and then drive for 13 minutes at speeds between 15mph and 35mph.
H. Accelerate to 53-56 mph and maintain speed for at least 6 minutes. It is more important to maintain accelerator pedal position than speed in this step. You are allowed a 3 mph variance in speed, but must try and keep the accelerator pedal steady.
