What is an ECU unlock?

Newer Bosch MD1 and MG1 control units may use protection that restricts reading and writing with tuning tools. During an ECU unlock, we process the removed unit so that a compatible tool can subsequently work with it on the bench.

This mail-in service is intended for workshops and tuners stopped by a locked ECU. The exact method and support depend on ECU version, part number, vehicle and tool protocol. Every job therefore starts with a free compatibility check using the registration number and a clear photo of the ECU label.

Once complete, we return the control unit to you. Engine tuning can also be ordered in the same enquiry, allowing both the unlock and requested calibration to be handled while the ECU is with Revtech.

Check before shipping

We verify the MD1/MG1 variant, part number and your tool before providing delivery instructions.

Secure packaging

Ship the ECU removed and protected against moisture, impact and static electricity. Shipping is additional.

Bench after return

Use a compatible tool and protocol. We can help check support for FLEX, KESS3 or AutoTuner.

Frequently asked questions

Questions about MD1/MG1 unlocking

Which ECUs can you unlock?

The service covers compatible Bosch MD1 and MG1 control units. Support varies by ECU version, part number and vehicle, so we always check the label and vehicle information before shipment.

Can I use KESS3, FLEX or AutoTuner after the unlock?

After a compatible unlock, the ECU can be read and written on the bench with a tool that supports that ECU and protocol. Tell us which tool you use and we will help verify the setup.

How should I ship the ECU?

Start with a compatibility enquiry. Once confirmed, we send the address and instructions. The ECU must be removed, dry, securely packed and protected against impact and static electricity.

How long does the ECU unlock take?

We confirm the handling time together with compatibility before shipment. Total turnaround also depends on shipping to and from Revtech.

Can you tune the ECU at the same time?

Yes. Engine tuning can be added for SEK 3,995 including VAT and completed while the ECU is with us. We confirm the vehicle and requested setup before work begins.

What if my ECU is not supported?

Do not ship the ECU before confirmation. If the specified version is not supported, we will tell you during the enquiry before shipping or service costs arise.
