If renault service remap my car for a update,could I have problems after to conect rstuner to my car?
if he does that then whats the point of the ecu update ?No, you will be just fine, depending on what exactly they do you will lose the fastchip calibration, but can be uploaded again. Just back up your ECU should you want that back. RStuner should be able to do that.
