Does Stage 1 ECU Tuning Damage the Car?

Stage 1 ECU tuning does not cause significant harm to the car. Below are the meaning and effects of Stage 1 ECU tuning: 1. Power Changes: Stage 1 ECU tuning only enhances the car's power based on the original factory settings without altering the hardware. However, the power improvement after Stage 1 tuning is not very noticeable. Typically, the power is increased by adjusting ECU software parameters. The cost of Stage 1 tuning is very low, involving adjustments to car parameters such as fuel injection and ignition timing. For car owners who are not into modifications, it is not recommended to try this lightly, as the power improvement achieved this way is not very significant. 2. Meaning of Stage 1 ECU: It refers to adding the most basic ECU program to the car's original factory ECU, thereby increasing the car's output power and torque. The car does not require any hardware replacement; only the original hardware is needed for matching, making the operation relatively simple. 3. Negative Effects: The car will require higher-quality gasoline. For example, if the car originally used 92-octane gasoline, it may need 95-octane gasoline after ECU tuning. The car will also have higher temperature requirements. Since the engine works overclocked, a better cooling system is needed. This disrupts the car's balance, requiring the replacement of systems like brakes and suspension to achieve a new equilibrium.

What Oil Should Be Changed During the First Car Maintenance?

For the first car maintenance, it is necessary to change to standard original equipment manufacturer (OEM) oil or fully synthetic oil, which can reduce internal engine wear and extend the engine's service life. The time and specific items for the first car maintenance are as follows: Time for the first car maintenance: The first maintenance for a new car is at 5,000 kilometers or six months, whichever comes first. The first maintenance is free, and you can follow the mileage and time specified in the maintenance manual. Specific items for the first car maintenance: Change the engine oil and oil filter, clean the air filter; check whether the levels of various fluids are normal; inspect the generator belt and wiper blades for any damage; check whether the tire pressure is normal and look for signs of uneven wear, bulges, or damage on the tires.

Why does the Mercedes-Benz make a loud noise when starting?

Mercedes-Benz makes a loud noise during cold starts because the arrangement of the exhaust manifold places the catalytic converter too far back. The catalytic converter must reach a certain temperature to effectively filter exhaust gases. Therefore, to quickly heat up the catalytic converter, the exhaust valve closure is intentionally delayed during cold starts, causing the air-fuel mixture to enter the exhaust manifold and combust, resulting in the loud noise during cold starts. Here is some related information: History of Mercedes-Benz: Mercedes-Benz was founded in 1926 by Karl Benz and Gottlieb Daimler. Its predecessors were the Benz & Cie. and Daimler-Motoren-Gesellschaft, established in 1886. The two companies merged in 1926 to form Daimler-Benz AG. Mercedes-Benz Logo: The Mercedes-Benz logo is a three-pointed star, symbolizing the ambition to dominate land, sea, and air. This emblem was created after the merger of Daimler and Benz. The original Daimler logo featured a three-pointed star, while the Benz logo had the word "BENZ" inside a double circle. After the merger, the Daimler-Benz logo became a three-pointed star inside a single circle. Making the three-pointed star shine globally has been Mercedes-Benz's dream for over a century and remains its relentless pursuit.

What is the reason for the tire pressure warning in the Mercedes GLB?

Mercedes GLB displays a tire pressure warning because the pressure in one of the tires is either too low or too high, but has not yet reached the warning threshold. It is necessary to check the tire pressure. Tire Pressure Monitoring: Tire pressure monitoring involves real-time automatic monitoring of tire pressure during vehicle operation, alerting the driver in case of tire leakage or low pressure to ensure driving safety. Common tire pressure monitoring methods include: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors tire pressure. Indirect tire pressure warning systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and a four-wheel indirect system is also employed. Compared to a fully direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires as effectively as a direct system.

Is it necessary to ride the motorcycle for the transfer of ownership?

It is required to ride the motorcycle for the transfer of ownership. Additional information is as follows: Vehicle inspection. Drive the motorcycle to the inspection site for external inspection, tracing the vehicle identification number, removing the license plate, and taking photos. Obtain the vehicle photo and attach it to the inspection record form, then proceed to the transfer hall for filing procedures. License plate selection. After obtaining a number from the number dispenser, queue up with the relevant materials to pay the transfer fees. Transfer and relocation: Required materials include the Motor Vehicle Registration, Transfer, and Cancellation Form/Application for Transfer, inspection record form, original motor vehicle property registration certificate, original driving license, original owner's ID card, original license plate number, vehicle photo, and transfer invoice from the trading market. Documents required for motorcycle transfer: Original motorcycle driving license. Owner's ID card and a copy. Transferee's ID card and a copy. Uniform invoice for second-hand vehicle sales transfer registration. Motor vehicle registration certificate. Motorcycle transfer process: Both parties involved in the motorcycle transfer should go to the Vehicle Management Office to collect the "Motor Vehicle Inspection Record Form" and the "Motor Vehicle Registration, Transfer, and Cancellation/Transfer Application Form". Ride the motorcycle to the inspection site for external inspection, tracing the vehicle identification number, removing the license plate, and taking photos. Obtain the vehicle photo and attach it to the "Motor Vehicle Inspection Record Form", then proceed to the transfer hall for entry procedures. After queuing up with the relevant materials for entry, pay the transfer fees (15 yuan). At the designated counter, a new driving license will be printed according to the serial number, and the old driving license will be collected. Update the information on the motor vehicle registration certificate.

Why Should Vehicles on the Main Road Yield to Those on the Auxiliary Road?

Due to high traffic volume, the main road serves as the trunk line while the auxiliary road functions as the branch line. Vehicles on the branch line should yield to those on the trunk line. Generally, main roads have more lanes and higher speed limits, so vehicles on auxiliary roads must yield to those on the main road. Below are relevant details: 1. Auxiliary roads in urban expressways should be located on one or both sides of the main road. For elevated roads, auxiliary roads should be set at ground level beneath the elevated structure. In urban areas, auxiliary roads should be continuously arranged, while in suburban expressways, they can be continuous or intermittent. 2. Auxiliary roads on both sides of the main road should adopt one-way traffic, whereas those on a single side may allow two-way traffic. 3. Elevated roads and ground-level roads should be connected via on-ramps and off-ramps.
