Alientech KESS3 Slave Bench-Boot Protocol activation for Marine & PWC. Included 12 months of subscription.
The Alientech KESS3 replaces the Alientech KESSv2 and Alientech K-Tag which have probably been the most popular tuning system and tool anywhere over the past 10 years or more.
Unlike the previous Alientech tuning tools. The KESS3 has the ability to be activated either as a Kess3 Master tuning tool, or a Kess3 Slave tuning tool. In addition, it can be activated as either OBD, Bench/boot, or Both. So the one single Kess3 can offer both OBD tuning and Bench / Boot tuning from one device.

As such, the new Kess3 offers unbelievable coverage and flexibility. This combined with regular updates, low running costs and ability to move from slave to master. And OBD to Bench / Boot makes the Alientech KESS3 the leading tuning tool. The Alientech KESS3 does not come with tuning protocols as standard, this item is the hardware and basics cable set.

You can add protocols (vehicle coverage) in our online shop too.  Just 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 and we will be happy to arrange this for you.

For each Alientech KESS3 you purchase with Slave protocols, you will need to link it to a KESS3 with Master protocols who will provide your tuning files, software, and support. If you don’t have a master ready to support you, we can do this directly. If you do have a master tuning file provider ready to support you, please confirm the details of the master the KESS3 with slave protocols, so we can pair your tool as soon as you order.
