After years of development and rigorous testing, it can be said to have been sufficiently mature and stable to become a standard business for foreign sales. 2. High performance and high value for money can increase by 8 to 15 per cent after a normal natural air-inhaling vehicle is brushed, while a turbo-pressure vehicle can increase more significantly, from 20 to 40 per cent. Maeten 1. 8 tsi, 250 nm for the original twister, 325 nm for the euu upgrade, 30 per cent up, 0-100 km per second. If the computer is not painted, it will cost at least 20,000 or more to achieve this performance, and the eu will cost thousands, so the value is quite high. 3. Low access to different car computer data is fully tested by equipment companies when developing reading and writing protocols, while protection mechanisms have been developed and equipment is automatically identified and stopped before operation due to operational errors or incorrect connections. The foreign calibration process is strictly tested, the computer itself has a self-checking function, and normally the post-testing instrument is normal and can be readjusted, even if there is a problem, and it can be restored to the original vehicle data at any time, since the data are backed up after reading the original vehicle data, so it can be said to be virtually zero. No negative impact. Odi a4l, a6l and q5 2. 0t have the same engines, a4l is 320 nm, a6l is 280nm, q5 is 350 nm, and we have swiped a6l to the level of q5 and are safe. The upgrading of the ecu is also an optimisation of the engine, which, because of the accuracy of the calibration and the more abundant combustion, will reduce the carbon accumulation of the engine and the emissions of the gas, which is why the ecu has improved its fuel consumption and reduced it. Since the process of upgrading the ecu was procedural, it was not apparent from the appearance that it would affect the annual inspection and review. The upgrades, again, are based on the original vehicle data and do not affect any electronic equipment in the original vehicle, nor do they affect normal computer diagnostics, so they do not affect the maintenance of the vehicle. With the introduction of internationally advanced equipment and cutting-edge technology in max, the upgrading of the euu has become extremely simple, with a vast majority of car-type computers free of demolition, so that vehicle detection points can be upgraded. Even for upgrades that need to be done by dismantling computers, all can be done with a small table by one person, as some of the upgrades have very few practitioners and few space. Technology is highly monopolistic, and equipment cannot be decrypted due to the fact that the epu upgrade equipment is purely imported abroad and requires online confirmation when reading and writing data. It is also a difficult project, which must be carried out jointly by foreign auto engineers and software engineers, and even domestic vehicles will have to use imported brand computers, which is far from universal. The equipment was tied to the programme company prior to its sale, the same equipment was not shared among different programme companies, the same vehicle could not be reused in other vehicles, the same procedure could be written only once and not automatically expired within 24 hours. So the upgrading of the euu is a highly monopolistic technology industry. 7. The low-cost, ceu-upgrading project is essentially a one-time smart choice for equipment, with no other administrative costs than a small annual fee for equipment in the second year, so fixed costs are minimal. For each car, it is only necessary to pay for the transfer of one car, overpaid, underpaid and balanced. Due to the low level of competition and the high level of technology monopoly, it is clear that the payments for the promotion are significant. It is simple to upgrade the euu, which can read and write data with a few mouse points on the laptop software for a computer-free car. Even with the computer upgrades, most of them are simply welded on circuit boards for reading and writing data. Only weld chip cars need a strong hands-on capability, and if you're an electronics practitioner, like mobile phone maintenance or computer maintenance, you can easily break weld chip. Data can be sent back in about an hour to a foreign reviser, plus about two hours to read and write, i. E. An upgrade of a car for about two hours, with extremely short and efficient working hours, and a few shifts per day or even ten times a day if all the cars can be changed together. Once the data are written, it can be tested, and it can work, and when it works, it can request money, so the funds are recovered quickly and there are no bad debts. As a result of the operationalization of the euu, tens of thousands of dollars of equipment can be spent on 10 cars to achieve the goal and achieve it quickly. Since the data are sent abroad for adjustment, because of the time difference between 2 p. M. And 11 p. M., the hours of the morning are closed, which means you have half a day off every day. The equipment upgraded by the eutu is small and light, plus a laptop that can easily access the house in a small bag, without any restrictions. The promotion process, because it takes about an hour to wait for data from abroad, is usually a time to have tea and chat with guests, to be able to make friends, to be able to run and enjoy the promotion with the owner of the car
