From the first steps in the world of karting up to the highest levels, the jetting is always the deciding factor to compete at the top, in fact, the tight regulatory constraints force you to work on details and optimal tuning of chassis and engine is essential to be competitive. For this we have developed the software for all major categories, thus allowing everyone to optimize the carburetion in few seconds. The software is intended for professional use, but given its ease of use is also ideal for beginners and inexperienced for which is particularly instructive allowing to make immediately a a quantum leap technical and of performance.

With our test team and the many users that we've in different countries of the world the software have a refinement continuous to be always updated at the technical and regulation novelties that are introduced.

We don't know the regulation in the different countries, but below you can see like the software SET-UP Carburetor has been developed for all the main model of carburetor and for all the main categories of kart then if you don't see your model write us to have information.

Thanks to the authors and their publishers. It is highly recommendable to read theese books.
