Computers have no influence, but if you use computer shunting equipment, you should be very careful when adjusting it greatly. Occasionally carelessness will bring disastrous consequences to the engine.
1. Its functions are very extensive, such as allowing the fuel supply and ignition to be changed greatly, boosting value of turbine engine, switching timing of Vtec and fuel cut-off limit of engine, etc. Especially for the modified car, the external computer can give full play to the potential of the modified car, and most of the original electronic functions of the car can still be retained because of the existence of the original ECU.
2. Plug-in computer is a tool to increase the horsepower and torque of each car by 10-35% without increasing fuel consumption and completely matching the original diagnostic system, which greatly improves the power connection when starting, overtaking and shifting gears.
3. The difference between plug-in computer and brush ECU: Generally, plug-in computer can improve certain power by adjusting some ECU signal parameters, which has the advantage of being safer and cheaper than brush ECU. In contrast, the disadvantage is that the power promoted by brushless ECU is larger. The external computer can be restored at any time, but it cannot be restored by brushing ECU. While there are advantages, there are also shortcomings in real estate: installing a plug-in computer without brushing ECU.
