Geez, it's not that hard at all. Almost all vehicles sold in the west conforms to CA emissions standards. Just look at the Emissions label and it will say EPA Or EPA and California. A pickup bought in TX by a friend was CA emissions compliant.
Now as for the computer check, the issue is that regardless how many miles you drive, if you don't hit all they requirement points for the computer, you can drive till you run out of fuel and still never read ready. The best way is to follow what the manufacture states is the proper drive cycle otherwise you may miss one or two critical items and fail.
You have to have so much warm up. So much low speed driving. So much high speed driving. Plus you may need to have a certain amount of idles between different driving along with a possible turn off and ons to complete the proper breaking run cycle. On some vehicles you may be able to hit all the requirements through normal driving, but on others, specific things still need to be done. Just ask the dealer for the proper method (if not already specified in your owner's manual).
