Alientech just dropped the Upgrade 3.08 for KESS3, and it adds something many tuners have been waiting for — a new BENCH mode protocol for Bosch MED17.8.10 ECUs. These units are found on DR 4.0 vehicles with 1.5 engines from 2022 onwards, and now you can access full read & write functions straight through the ECU connector without invasive procedures.

This update expands what you can do in your workshop, giving you stable bench operations and complete control over engine strategy data with KESS3.

Make sure to update your KESS3 to Upgrade 3.08 and unlock this capability.
