As far as user friendliness I would rank the Holley as one of the better ones. There are a couple of little idiosyncrasies but all in all they are good. You will basically have to input engine basics such as displacement, injector size, sensor types and so on. They do have a few base maps you can start with as a template and just plug in your data. This is good because it will start you off with a populated spark and VE map. The DBW stuff is probably the easiest thing to set up. That part is done with step by step instructions in the software.
