Stage 2 Bench Flash — BMW M340i

Some ECUs are locked against writing over the diagnostic port. On those, the unit comes out of the vehicle, gets opened on the bench, and is written directly.

How it works

1. Order here and print the packing slip we email you.
2. Remove the ECU and post it to us, wrapped in anti-static and packed properly.
3. We read the original file, archive it, and write the new calibration.
4. The unit ships back the same or next working day, tracked.
5. Refit and ride. No adaptation reset needed.

What we need from you

VIN, mileage, exhaust and filter spec, and the fuel you run. Put it in the order notes.

Bench flashing carries an inherent risk to the ECU. If the unit has been water damaged or previously flashed by someone else, tell us first.
