If you're not confident with computers, you can always send us your ECU in the post so that we can remap it. This option is available for all Bosch EDC15 (2.0 and 2.2), Siemens SID801 (2.0 90), EDC16 (1.4, 1.6 HDI) and Siemens SID803 (2.0 16V 136BHP)..

To use this service all you need to do is:

1. Remove the ECU from your vehicle. Make sure the engine is off, and for safety disconnect the battery. Remove the backing tray as this increases postage costs at both ends.

2. Tell us which remap you're after and any other options such as DPF or EGR removal. Include a note in the parcel. Important: Include a return address label ready to be attached to your parcel, also include a note with your name and the remap you require.

3. Wrap the ECU in bubble wrap ensuring the plastic plug connectors can't get damaged. The ECU is fairly tough, so there's no need to over do it. Remember, remove the metal tray with two 10mm nuts.

4. Post the ECU using or Royal mail. Make sure it is recorded/tracked. Please DO NOT use Special delivery, as this actually takes longer as Royal Mail won't leave in our designated safe place if we are not available to accept delivery.

5. Send payment of £150 through the online payment page (or for EDC17 £200).

6. As soon as we receive your ECU, we will remap it, and send it back to you using first class recorded delivery. It is important that a note is included with all details of the remap required and the return address as on some days we can get multiple ECUs delivered.
