Cat Monitor Not Supported

mults

So...I've been tuned by EcuTek for the past 3 years and today, I ran into my first dilemma. In 2017, I tool my car to Dynosty and had Hal tune my 40th Anniversary with my bolt-ons. The car ran so much better, and I am so glad that I had it tuned.

Fast-forward to today. I live in a county in Ohio that has a requirement to have the car pass an E-Check in order to renew my plates. I had to have this done in 2018, and all was perfect. When I went today, the screen flashed "Cat Monitor Not Supported" and the car failed. The tech showed me his screen where the cat monitors were turned off and asked if I had a tune. I said yes, and he suggested that I need to have the original, factory map reinstalled. So, my questions is: Why did it pass in 2018 and not now? Is Ohio monitoring more parameters, or did I not go through a proper drive cycle?

Lastly, has anyone used a EcuTek programmer from another vehicle (my friend has one for his GT-R). Once I get my factory map back, would his ECU kit work to get the factory map back into the Z?

Thanks for any information to help me figure out what the next step is...
