HPT doesn't have the ability to remove the test unless they added it since they updated to 2.23.
I actually have the newest version, which is 2.24, but honestly have not looked at the program since downloading his stock tune so I could license his VIN.

Found in the top sticky on this section. It looks like I can have the sensor functioning, but simply turn off the SES light and it would do the CAT test once, fail, then ignore. Is that not right? or am I still fuzzy on that whole 9 page thread?
