Rick. Software updates are embedded in BUDS, and BUDS2 for that matter. The latest version of BUDS is version E3.8.2.1, last updated in 9/23/2016. (Menu Bar-Help-About BUDS) So, when you downloaded that, it contained the update for your 2013. Same stuff the dealers get, different delivery method. Everything about your 2013 is now up to date.
Unfortunately, your 2013 still has the old DESS system. That was changed starting in 2014. You won't be able to disable DESS. But, it's been so reliable that you don't need to. But, you can disable DESS for everyone else with a 2014 up to 2017. They'll appreciate it.
But, when you get your hands on a service manual, you can learn how to go through your sensors and make sure that they're zero'd properly - it'll steer better - and the VSS system will work properly. Start up BUDS without the MPI hooked up, go to Open a file, but go up one level in the folder, and you'll see an Auto Save folder. BUDS auto saves a copy of the Spyder's document each time you hook up. Open the latest Auto Save file and then just surf around with all the pages and tabs. You don't have to be hooked up to your machine, that way. And you can look at the Demo files, too, of course, but the Auto Save file is your specific machine. Have fun with it, but most of all, if it ain't broke.......
PS. A bit surprised that your 2013 was out of date. Would have thought the ECM was brought up to date when the 2013 recall was done. But, maybe this update came along afterwards.
