This application is a collection of all our checksum plugins in a single standalone package.

What are checksums? A checksum is a value that is calculated from a block of digital data with the scope of being used in the future to verify if this data has been modified in any way. So basically if you change any of the maps in your cars ECU the currently saved checksum/s will not be correct and your car in most cases will not start.

The licensing system allows installation on multiple computers and the execution of the application is permitted on one computer at a time by use of a usb dongle.

If you would like to purchase the application please contact us by email from the contact page.

All future updates are free and can be downloaded from our files repository when you login to our server with your account.
