What are the symptoms of a faulty CNG conversion ECU?
3 Answers
When the vehicle's ECU fails, the following phenomena may occur: 1. The dashboard may display erratically or appear dim. 2. The onboard computer screen may show no display at all. 3. The vehicle may not display power or allow ignition. 4. In severe cases, even the car doors may fail to open. Relevant information about vehicle modifications: 1. Regulations: According to motor vehicle registration regulations, any changes to the body color, model, performance, purpose, or structure of a licensed vehicle, including replacement of the frame, body, or engine, must be reported to the vehicle management office for modification registration. 2. Benefits of wheel rim modification: Upgrading to high-quality rims can improve heat dissipation and achieve weight reduction, offering high visual impact both statically and dynamically while enhancing the vehicle's handling performance. Increasing rim diameter and width while reducing aspect ratio can comprehensively improve tire grip.
Ever since I was young and started driving, I've been tinkering with car modifications. The symptoms of a faulty CNG system ECU are quite obvious: the car simply can't switch to gas mode and stubbornly stays on gasoline; the engine shakes violently at idle, like it's having a seizure; throttle response becomes sluggish during acceleration, lacking power when overtaking, and fuel consumption suddenly spikes; the dashboard occasionally lights up with a warning light, but not consistently. These issues not only affect driving mood but can also damage the engine, leading to higher costs over time. I once experienced this on the highway when the engine suddenly jerked, nearly causing an accident. After replacing the ECU, everything smoothed out, saving fuel and giving peace of mind. It's important to pay attention to these signals while driving and address repairs early to avoid major overhauls.
As an ordinary person who often takes family trips, I pay great attention to safety. It's really scary when the LPG ECU fails: difficulty starting the car, requiring multiple attempts; unstable idle speed while driving, with severe shaking, especially prone to stalling at traffic lights; inability to switch to gas mode, leading to a sharp increase in fuel consumption; warning lights constantly flashing. This not only poses safety hazards, such as breaking down in traffic, but also increases expenses. After my personal experience, I found that timely repair of the ECU made driving smoother and significantly improved safety.
