Having have used the product first hand. It is great the first thing you do if you don't have a base map is wire it so it can it learn the a fuel map for you. Then you rewire it so so you can get rid of the MAF and use the MAP sensor instead.
It has secondary outputs for a using it with nos and has the ability to do logging from say a wideband.
Overally it is a good product as it is basically a VPC and E-Manage type unit and a much better price with great capability.
