Here is a deeper look at the limitations and benefits.<\/p>\n<p><strong>1. File Editing and Encryption<\/strong><\/p>\n<ul>\n<li>Slave Tuning Tools: These tools can read and write a file from a vehicle. However, the tool cannot open the file for editing or modification. The files read by a Slave tool are encrypted and can only be opened by the specific Master tool it is paired to.<\/li>\n<li>Master Tuning Tools: With the correct map editing software and training, a Master user can read, open, and edit their own files. They can also buy modified files from an unlimited number of file suppliers.<\/li>\n<\/ul>\n<p><strong>2. Provider Flexibility<\/strong><\/p>\n<ul>\n<li>Slave Tuning Tools: You are locked into a relationship. You can only receive tuning files from the specific Master Tuning System your tool is paired with.<\/li>\n<li>Master Tuning Tools: You have total freedom. You can source files from any provider, or write your own if you have the skills.<\/li>\n<\/ul>\n<p><strong>3. Upgrading Your Equipment<\/strong><\/p>\n<p>Many Master operators may not advertise this, but Slave tools can be upgraded.<\/p>\n<ul>\n<li>Slave tuning tools can be upgraded to the Master tuning tools platform.<\/li>\n<li>You typically only pay the price difference between the two tools.<\/li>\n<li>Important: You can only upgrade if your current Master gives permission for the release.<\/li>\n<li>Note on Upgrades: While some Masters may hesitate to release a Slave tool, VIEZU will always allow this upgrade. We can support the release of your Slave Tuning Tool to become a Master and assist with Training, Technical Advice, and Tuning Files.<\/li>\n<\/ul>\n<div id=\"attachment_9447\" style=\"width: 872px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/remap-staging.24livehost.com\/wp-content\/uploads\/2022\/02\/alientech-kess-3.png\"><img decoding=\"async\" aria-describedby=\"caption-attachment-9447\" class=\"size-full wp-image-9447\" src=\"https:\/\/remap-staging.24livehost.com\/wp-content\/uploads\/2022\/02\/alientech-kess-3.png\" alt=\"What is the difference Alientech Kess Slave and Kess Master.
