Who has ever used a small magnet? Does it have a negative impact on the car?

1.There are downsides to upgrading the ECU.

After upgrading the ECU, the most basic and one parameter that the ECU must modify is the ignition advance angle. The original car factory took into account the differences in oil products across the country, and adjusted the ignition advance angle to a most adaptable advance angle. After upgrading the ECU, foreign engineers will inevitably advance the ignition advance angle to achieve the best ignition angle.

Therefore, the problem arises, for most parts of the country to use unleaded gasoline, after upgrading with 97 gasoline, you can upgrade the engine of the ECU.

Play at your best. On the contrary, at present, some cities in China use ethanol gasoline, ethanol gasoline has the characteristics of flammability, short combustion process, appropriate ignition lag will make ethanol gasoline burn more fully, and then upgrade ECU is to ignite in advance, it will cause engine detonation, weakness, long-term use will damage the engine. However, if unleaded gasoline is the opposite, the appropriate advance will make the mixture in the engine burn more fully, the carbon deposit will be relatively reduced, and the engine life will be extended.

Therefore, for cars in areas where ethanol gasoline is used, it is like refusing to upgrade the ECU for it. At present, the three northeastern provinces are ethanol gasoline, and many ECU upgrade companies have greatly promoted it, and car owners who want to use ethanol gasoline think twice.

2.The second disadvantage is that a proper degree of modification with good gasoline is very beneficial to the car. However, excessive modification may exceed the car's tolerance and damage the hardware.

The first stage, the second stage ECU program will not have any problems for naturally aspirated cars, turbine cars for several years. However, in the racing mode of German REMAPS, so far, there have been many transmissions that burst after upgrading the ECU mode of the racing car, the transmission burst, the half shaft was cut off, and even the automatic wave of the BMW 530 has skiddled and cannot withstand excessive torque. Therefore, it overturns the current belief in many people's minds that the naturally aspirated car is upgraded to the ECU

It didn't make much difference. So if you want to upgrade your racing mode, you have to think about it beforehand.

Do you suck on the oil filter, oil pan or gasoline filter?

Magnets can only absorb iron filings, which is almost useless for aluminum alloy engines, and there is no need to use magnets to suck out iron filings in the casting process of current cars.

The use of all-magnets may adversely affect the car body, as the strong magnetic field buried as a magnet can interfere with the electronic devices and computer systems on the car body. These devices include the vehicle's battery, engine control module, audio system, navigation system, and more.

If the magnetic field is too strong, it may cause these devices to malfunction or malfunction, affecting the performance of the vehicle and driving safety. In addition, using magnets can also leave scratches or abrasions on the body, especially if there are fine particles such as particles or sand between the magnet and the body.

Therefore, if you are considering using an all-magnet, it is recommended that you consider it carefully and consult the advice of a professional or experienced car owner before using it. Also, if you decide to use an all-magnet, make sure it is installed correctly to avoid unnecessary damage to the body.
