Alientech KESS3 Master OBD Protocol activation for Cars and LCVs.

Included 12 months of subscription.

The Alientech KESS3 replaces the Alientech KESS V2 and Alientech K-Tag, which were probably the most popular tuning system and tool anywhere for the past decade or more.

Unlike Alientech’s previous tuning tools. It is also possible to set the KESS3 to operate as a KESS3 Slave tuning tool, as well as a KESS3 Master tuning tool. You can also activate it as OBD, Bench / Boot, or Both. With one device, the KESS3 can perform both OBD and bench/boot tuning.

The new KESS3 offers unprecedented coverage and flexibility. Additionally, regular updates, low running costs, and the ability to migrate from slave to master and OBD to Bench / Boot tuning adds even more value and makes the Alientech KESS3 the leading tuning tool.

You can add protocols (vehicle coverage). Select from Cars, Bikes, Agricultural/trucks, and Marine protocols, or any combination of the protocol packages. If in doubt, please ask If you would like a demonstration of the Alientech KESS3 tuning system. If you contact our support team, we will be happy to arrange this for you.

Alientech KESS3s purchased with Slave protocols must be linked to a Master KESS3, which provides the tuning files, software, and support. If you do not already have a master, we can do this directly. When you order, please confirm the details of the master tuning file provider that the KESS3 with slave protocols is to be paired with at time of order, and we shall do the rest for you.

The Alientech tuning tools, software and equipment are available with worldwide mail order, free technical support, set up and installation assistance. Alientech tools are offered at trade discount prices and tax-free sales based on location – worldwide shipping and training are available.
