Hi, Have for sale a tuning box from RS250. Bought new car with the box, but will prefer some custom remap. Its been installed in http://www.renault-kirfel.de/ , for the company, it looks like they know what they are doing. Sadly i dont know what company exactly the box is, but maybe it is their own stuff. About the box, it haves the button/screw with 9 settings and its black coloured box, I will take some pictures later. They also told me that the box is unlocked, so any tuner can write a new software on it or change it. For the price, at first make me some offers if you are interested and we can discuss. Postage is about 30eur tops to UK.
Little search with the item no. from the unit, it shows that its for the 195kw version http://www.ebay.it/itm/SPEED-BUSTER...kW-10109576-/361191726476?hash=item5418b45d8c It was on 184kw version car and it was working fine so i dont know.
