Yes, it must be complete, or they will tell you to come back.there is a limit to how many monitors can be incomplete older cars is like 2, newer is 1I believe, but I'm sure all locations are different, just call your local emissions and ask how many monitors can be incomplete.Also, down in north Texas, you get like 3 chances to pass on the original fee.
catalyst is the easy one, just disable P0420 and that will pass catalyst. o2 heater requires the heater codes be disabled for both sensors, and the regular o2 test requires codes be disabled for everything related to o2 sensors. Evap i havent found a way to disable that test, but you can pass with it incomplete.

Well I used the OBD Link MX+ and my laptop (Windows 11 on a Dell) had a very difficult time trying to connect to it. When it finally did I kept getting the "Unexpected response to STPX payload: BUS BUSY" with PCM hammer until after 6 tries it finally seemed to read. Then when I went to read the uploaded file from the PCM to download it to ensure that the changes were made, it couldn't do it and gave me an error. Thankfully I was able to start my car after this and the changes seem to be made.
I am not sure why I am having such a hard time connecting to the OBD Link MX+ via bluetooth. I am thinking of going with the wired version (OBD Link EX) to try and skip any blue tooth issues. I would assume going wired would be faster? Otherwise I should probably look into OBDX Pro
