Pankhaniyi, simuyenera kusintha firmware kukhala Euro-2. Ndikofunikiranso kumvetsetsa kuti firmware sichikonza vuto ngati sensa ya oxygen ili ndi vuto. Chipangizochi chiyenera kugwira ntchito bwino, ndipo pokhapokha ngati injiniyo idzagwira ntchito bwino.

Ndizovuta kwambiri kuposa chosinthira chatsopano chothandizira kapena firmware ya ECU. The unsembe ndondomeko samatenga mphindi 15.

Pomaliza, m'pofunika kufotokoza mwachidule mfundo yakuti eni galimoto ambiri amaona kafukufuku lambda chinthu chochepa m'galimoto ndipo nthawi zambiri amangochotsedwa pamodzi ndi converters catalytic, akangaude 4-2-1 ndi mitundu ina ya kukhazikitsa. Komabe, njira imeneyi ndi yolakwika kwenikweni. Pambuyo pake, pali madandaulo okhudzana ndi mowa wambiri, mphamvu zochepa komanso ntchito yosakhazikika ya injini yoyaka moto. Mkwiyo waung'ono uwu (poyang'ana koyamba, nkhope yosamvetsetseka) ndiyomwe imayambitsa chilichonse. Ndikofunika kuyandikira kukonza galimoto yanu mosamala, chifukwa kusintha kulikonse sikungowonjezera kuwonongeka kwa magwiridwe ake, komanso kuchepa kwa moyo wake wautumiki.
