WAR chip sucks. Its not fully tunable. They provide a fueling and ignition curve and you can basically +/- the values from there within a certain range.
I am setting up VEMS on my car right now and documenting how to make the config file.
Go to
http://www.vems.hu/vt/ to check out the software (watch the videos too)
You can also talk to Gunni at GStuning.net about the system. He should be able to get a reasonable basemap for you.
VEMS is similar to MS in that its open source, but the hardware is SO much better. You dont have to solder crap together to get different functions, its all built in.
Nothing is really plug and play though and if you dont understand the concepts of tuning, the ECU can't magically do it for you.
