Where To Buy

Allientech KESS3




All in one tool

The Kess3 contains all of your OBD / Bench and Boot tuning hardware in one simple to operate the device. There is no need for an additional tool, or plugin extra modules into the Kess3 to enable BOOT or BENCH tuning. Simply pick the cables you need and get tuning


Flexibility, protocols are sold separately, so there is no need to purchase packages you don’t want. And new protocols can be added at any time. So a Kess3 that is only OBD active, can have bench/boot protocols added straight away. Meaning, you don’t miss out on work where new or different protocols are required.

Bench and Boot

Bench and Boot protocols are available to purchase individually. And by vehicle type for the first time. (Not sold by ECU manufacturer). Hence, making the tool set up much more specific, and cost-effective to your requirements

Light speed

Light speed! The brand new Kess3 takes advantage of some of the latest and greatest technology available to provide an incredibly fast reading and writing to both ECUs and TCUs, this means less time connected to the vehicle and means a faster turnaround remap you are carrying out.

Alientech Suite

The “Alientech Suite” program, which runs the Kess3, is an all-in-one program. No complex menus to navigate through. Select the vehicle you want to tune from the main home screen, select the method “OBD” / “bench – Service mode” / “Boot – Direct to ECU Circuit board”, then you can read and write.

Fast interface

The speed of the interface is faster than any previous Alientech program. Opening in ready to tune a vehicle in just a few seconds!

Quick filters

Quick filters to find the vehicle. No need to follow the drop-down menus in a long-winded order. You can now fast travel to the options you want. Filter by ECU or TCU – DONE! Filter by fuel type – DONE! It’s the easiest and simplest tuning interface in the marketplace.

Built for the real world

The new Kess3 has a protective rubberised layer around the outer edge of the tool to absorb shocks and bumps when it’s being used in real environments such as garages and “in the field” mobile tuning. Complete with none slip feet for added safety when working on a vehicle.

Clear instructions

Clear instructions are now presented to you before you proceed to the reading/writing screen when using Kess3. This prevents you from missing vital instructions and keeps you fully updated with the knowledge to complete the tuning safely.

Upgraded cable set

The new Kess3 cable set is so easy to use and comes with all the additional GPT style cables in the same simple to use plug and loom as the main power/earth, CAN high / CAN low and kline loom.

Warp speed checksum calculations

No more waiting around endlessly for checksums to calculate. The new processing power of the Kess3 crunches the data faster than any tool that came before it.
