TVR Car Club France

Hi,
My daily drive is a Subaru Legacy diesel, which has been remapped. The remap is not locked so, when I take it for its service, I need to be able to tell the garage that they must not touch, they must do nothing to the ECU, the electronic brain. Trouble is, I don't know how the French say 'ECU' and 'remap', can anyone help please?
Thanks.

Hi,
You can tell them that the car has been re-programed: re-programmée
And that they should not update the electronic: ils ne doivent pas mettre à jour l'électronique moteur (yes it's a software but I'm not sure that they will understand "logiciel").
Someone else has another idea?
Regards,
Zeb
