Hi Edute, Mira Peugeot is a slightly complicated brand, I do not advise the change of ECU in any case and less for Ecu de Desguesses, now in any case you will have to take the vehicle to a workshop where you have a Escnner to be able to save the problem, both of the Biejo and the new computer and if you want I am interested in what was your original problem with the old ECU, when buying in them you have to be very careful because there are vehicles that are the same model of the same year and everything but the ECUs work with different systems, the case is given a lot, but for your tranquility a good scanner, not necessarily that of the house, can erase the codes of the ECU and the vehicle will work correctly, I tell you because I repair a Peugeot 307. The problem of this vehicle was that I did not raise speed and shit, an irregular relief and pulls in the walk, in addition the instruments went crazy and the car tended to stop O accelerare, quando ho messo questa vettura sul mio scanner mi ho lanciato, come 10 codici di errore, tagliando gli iniettori, bobine corte su massa, valvola EGR, TPS e altri, cancella la memoria e la fornitura, non l'ha mai fallito, non è mai necessario fallire. Ad esempio, faccio pagare circa 20.000 a 25.000 pesos cileni. Eye che prescrivere il computer non è uguale alla cancellazione dei codici di errore.
