ECU AND ENGINE REMAPPING
Our ECU remapping service is built around reliability and drivability just as much as performance. Every Autotech Tuning remap is custom-tailored to your specific vehicle and your personal driving preferences — because no two cars, or drivers, are the same.
All our remaps are developed and tested on our rolling road, ensuring real-world accuracy and results you can feel from the moment you start the engine. Whether you’re looking for a fuel-efficient remap to gain those extra miles per gallon, or a high-performance tune that unleashes your vehicle’s full potential, we’ve got you covered.
At Autotech Tuning, your vehicle’s safety and longevity always come first. Every map we create is designed to deliver smooth, safe, and reliable power — giving you the perfect balance of performance and peace of mind.
- We will not overstate our figures to make them appear better than our competitors
- We will not raise your expectation of fuel savings, to a unreasonable level
- We will tell you if the improvements on your car are minimal and therefore not worth doing
- We will never pass on or sell our customers data
What Our customers Say
KESS3 increases speed and safety in the workflow dedicated to Bosch MDG1 “Locked” ECUs, introducing new BENCH protocols that can be used after the unlocking procedure.
The development covers Bosch ECUs already supported in BOOT “Unlock” mode: MD1CS003, MD1CS069, MD1CP007, MD1CS012, MG1CS042, MD1CS004 HW80, MG1CS031, MD1CP006, MD1CS005 and MG1CS002, installed on a wide range of petrol and diesel applications from 2021 onwards.
The first operation is to unlock the ECU: using the Unlock Module accessory, access the ECU and perform the BOOT unlock procedure, applying the required patch.
Once this step is complete, you can connect directly to the ECU connector and work in BENCH, without having to open it again.
The benefits for everyday workshop operations:
Unlock protected ECUs directly in the workshop
Direct access in BENCH after the unlock
Complete backup of ECU contents
Greater operational continuity on latest-generation cars, LCVs, heavy-duty vehicles and tractors
The Unlock Module is the initial access point that enables a faster, smoother workflow for subsequent operations and allows you to independently work on some of the most in-demand Bosch MDG1 ECUs on the international market.
The new protocols are available to KESS3 users with CAR BENCH/BOOT activation and an active subscription. The KESS3 Unlock Module is required to perform the BOOT “Unlock” procedure.

KESS3 expands the range of operations available on the latest “Locked” Bosch MDG1 ECUs and introduces a new dedicated accessory: the KESS3 Unlock Module.
This new accessory is specifically designed to perform the “Unlock” procedure directly in the workshop on MD1CS003, MD1CS069, MD1CP007, MD1CS012, MG1CS042, MD1CS004 (HW80), MG1CS031, MD1CP006, MD1CS005 and MG1CS002 ECUs. Once the unlock is complete, the ECU can then be programmed in BOOT mode, accessing its memories to perform reading, writing and a complete backup of the contents.
This update expands coverage across a wide range of diesel and petrol applications equipped with protected ECUs, produced from 2021 to the present day: from commercial vehicles to high-performance cars and SUVs.
The benefits for everyday workshop operations:
Unlock protected ECUs directly in the workshop
KESS3 Unlock Module dedicated to managing the BOOT “Unlock” procedure on supported ECUs
Access to ECU memories after the Unlock procedure
Reading and writing in BOOT mode
Complete backup of ECU contents
Greater coverage of multi-brand diesel and petrol applications
New opportunities to work on commercial vehicles, cars and high-performance SUVs
With KESS3 Unlock Module and KESS3, you can manage the entire operation directly in the workshop, maintaining control over every stage of the process: from the initial ECU unlock to memory access and subsequent programming in BOOT mode.
The KESS3 Unlock Module is already available in Dashboard, in the section dedicated to KESS3 accessories.
The new protocols are available to KESS3 users with CAR BENCH/BOOT activation and an active subscription. The KESS3 Unlock Module is required to perform the BOOT “Unlock” procedure.
