633 is the code that everyone gets when they install the stage ecu's. it's nothing, don't worry about it. of course that is that you don't have a stage ecu then it's an issue. otherwise, it's just there to annoy you. won't throw a check engine light, but it's always there if you pull the codes up. the evap code is probably your gas cap. check it, make sure it's tight. then reset the ecu and see if it comes back.
haha it means that you're not doing it right. if you have no codes (which you do, anytime a check engine light is thrown there are codes) then it will display "done". you have to hold in the key lock when cycling it so that it goes to the "on" position.
