A single flexible device that can be configured as required, when the tool is initialized, you can choose the mode of operation.
 
MASTER :The configuration that allows you to edit software calibrations in a completely autonomous way. The read files can be interpreted by your choice of remapping software.
 
SLAVE: If you are not confident yet or sufficiently autonomous in editing software calibrations, thanks to this mode you can work with a network of trainers who will support you file requirements.

About KESS3 Subscriptions:

Starting from March 27, 2026, KESS3 subscriptions will fully adopt a new model. 
All subscriptions will be standardized to a 12-month term, with only the following three types: 
I. Pricing Structure (MASTER / SLAVE) 
MASTER
Early Renewal → €990
Renewal → €1,190
Reactivation (if not renewed for more than 12 months) → €1,390 
SLAVE
Early Renewal → €490
Renewal → €590
Reactivation (if not renewed for more than 12 months) → €690

No other types will exist; all cases fall under one of the three above.
 
II. Operational Logic 
Early Renewal
The customer's current subscription is still active, and the renewal is completed before expiration.
The new 12-month term starts from the original expiration date, so the customer does not lose any usage days. This option offers the lowest price. 
Renewal
The customer's subscription has expired but for less than 12 months.
The new term starts from the actual renewal date.
The gap between the expiration date and the renewal date will be automatically aligned by the system, with no adjustment required. 
Reactivation
The customer's subscription has been inactive for more than 12 months.
The new term starts from the reactivation date.
This is the highest-priced option (designed to encourage customers to maintain continuous subscription).
