Hello Ale on the other hand, I have been driving an IVECO 50C13 Bj.99 since recently rejected my 508 because taxes, driving bans and fuel prices have tightened the loop around my wallet. I am a little scared about the high consumption of the IVECO. On the transfer trip I had eextremely rushed and chased it with 120km/h, using 18l. The next tank filling was so 50% city traffic 50% highway, it was at 16l. Last WE on the highway with point 100km/h needed e r 15l and on the return trip I drove with the trucks with 88km/h and lay at 12,4l. For my feeling this is too much for such a modern engine, I have a big box on it, but I want to turn something there. First it would be appropriate to check whether the sensor technology works so well, unfortunately I lack the idea. If someone has a book recommendation, I am always open for it. Does someone have some tips on how to check the corresponding sensors? What do you think? Are you from Chiptuning at the engines? Greetings from Berlin! MAtthias
