ECU flashing, currently also known as ECU upgrade, automotive computer upgrade, or ECU modification in China, is in fact officially referred to as ECU tuning. Below are specific details about ECU: Components: It consists of a microcontroller (MCU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), as well as large-scale integrated circuits for shaping and driving. Operating Range: The ECU typically operates within a voltage range of 6.5-16V (with voltage stabilization devices at key internal points), a current range of 0.015-0.1A, and a temperature range of -40℃ to 80℃. Primary Function: It controls the vehicle's driving state and enables various functions. This is primarily achieved through data collection and exchange via various sensors and buses to determine the vehicle's state and the driver's intentions, then manipulating the vehicle through actuators.

Can Temporary License Plates Still Be Used After the Official Ones Are Issued?

In theory, temporary license plates become invalid once the official ones are issued. If you continue to use them and are caught by traffic police, it will be considered as intentionally covering the license plate, resulting in a fine and 12 penalty points. More related details are as follows: 2. Continued use of temporary plates: The only purpose is to evade electronic surveillance using temporary plates, but this significantly increases the risks for the new vehicle and is highly prone to accidents. Taking such a big risk just to use temporary plates for a few more days is not worth it. 3. Precautions: It's important to note that in most cases, the DMV does not reclaim temporary plates, so you must destroy them yourself. When destroying them, make sure to tear them into pieces before disposal and avoid discarding them directly to prevent misuse by others.

What Causes the Abnormal Noise in a Cold Cummins Engine?

Cummins engine cold start abnormal noise is mainly caused by the following reasons: Engine oil related issues: The engine lubricating oil flows back to the oil pan. When starting the car, lubrication cannot be provided immediately, resulting in a ticking sound. Purge valve related issues: During engine startup, the carbon canister solenoid valve adsorbs gasoline vapor and introduces it into the cylinders through the vacuum effect of the intake manifold. This process may produce abnormal noises. Battery problems: If there's abnormal noise during cold starts along with failure to ignite, and the battery warning light and engine warning light illuminate on the dashboard, this typically indicates battery issues - either insufficient charge or expired battery life.

Is it bad to fill up the gas tank in summer?

In this case, it is not recommended to fill up the car's gas tank in summer. Here are the relevant explanations: 1. Filling up the tank too much causes gasoline to evaporate faster: Faster gasoline evaporation first leads to energy waste. Secondly, the evaporated gasoline smell can flow into the car cabin, and long-term inhalation can affect human health. 2. Filling up the tank too much can severely reduce the performance of the carbon canister: This ultimately leads to issues such as engine shaking and increased fuel consumption. 3. There are certain safety hazards: The car's gas tank has a vent hole at the top. If the tank is filled up, gasoline can easily overflow from the vent hole. If there happens to be an open flame, the overflowing gasoline is very likely to ignite.
