The new car's electronic engine management system is designed to provide reasonable performance and emissions over a wide range of fuel conditions and a wide range of weather conditions. In a specific ECU fuel consumption comparison test conducted under laboratory conditions, they are also programmed to provide the best fuel economy. This means that the manufacturer's plan may not be suitable for your driving conditions and leave a lot of room for improvement. "Chipping" is a generic term for reprogramming an engine's electronic management system to improve performance, different performance characteristics, better fuel economy, or use different levels of fuel. This can be done internally by replacing the engine ECU and changing or reprogramping the internal or external chip by changing the signal from the auto ECU chip to the fuel injection system and igniter. Some ECUs can be reprogrammed externally in-situ through the OBD2 diagnostic scanner of a ca...

Generally, if cell phone device is tested as 200mA electric leakage when booting, the first choice is to replace USB tube. Of course, this is not absolute, the iPhone 6 we are going to fix today is not caused by the USB tube fault. Connecting the iPhone 6 with multimeter , the current shows 200mA. we directly replace a USB tube. The result is that the current is still in the 200mA position after waiting for a few minutes. So we wonder if there is another fault symptom happened, the last repair technician mentioned the iPhone 6 fingerprint is not good. When heard of this problem, we can basically judge where the problem is. Connecting multimeter and trigger the on-off current with 300-400 mA, this is not normal. There must be something wrong with the fingerprint 3V. Use the multimeter to test fingerprint 3V against the ground value, it is short. This kind of situation is generally caused by one of outside capacitance is short, dismantling it! Finally, we find out the...
