As mentioned, gotta jump it or flash the ecu to get rid of the code if you don't want to leave it plugged in. Ivans block off plates come with the plug. I just removed the smog off my 2016 ZX14R and didn't bother putting the plug in because I have the woolich device. Just realized the option isn't available to turn it off for my year of zx14r. So now I gotta go back in and install the plug.
