Beijing Aisen BMW X3 brushes ECU to increase power
As an SAV utility vehicle, the BMW X3 has gone through three generations of development since its birth in 2003, and has an unshakable position in the domestic luxury mid-size SUV market with its excellent handling. The BMW X3 is the style of the BMW X3 with its comfort, tranquility, and enhanced luxury, but the handling and driving pleasure are not missing. Even if it is not lengthened, a more modern exterior design, a more luxurious interior, a more high-tech functional configuration and a sportier handling pleasure are all in one, and the protagonist of today's operation is this 2.0T low-power BMW x3.
Beijing Aisen BMW X3 upgraded ECU to improve gear shifting
Beijing Aisen BMW X3 brushes the first order
BMW X3 xDrive25i is equipped with a low-power B48B20C 2.0T engine, the B-series engine integrates the traditional combustion chamber and crankcase, adopts the world's first water-cooled aluminum turbocharger, the coolant is designed to flow through the exhaust manifold position, this design can effectively reduce the engine temperature during high-load operation, improve the high temperature tolerance of the engine, and in the cold state, can quickly increase the water temperature to let the engine enter the ideal working state. The output is 135 kW / 184 hp / 5000-6500 rpm, and the peak torque is 290 Nm / 1350-4250 rpm. The drivetrain is mated to an eight-speed automatic manual transmission from ZF. For a multi-purpose SUV, sufficient power reserve is a must to deal with complex road conditions, for the power parameters of this car X3 25I, there is still a suspicion of a small horse-drawn car, after all, the BMW 320 with the same engine is also equipped with the same power parameters, and this topic has also been fulfilled in actual driving, starting and rapid acceleration power lag is still very significant, in order to expand the best power and handling of this car in China within a safe range, one-to-one customized brush ECU is a good option.
Why can Beijing Aisen BMW X3 brush ECU to increase power
First of all, the system detection of the whole vehicle is carried out through special equipment to ensure that the vehicle is optimized and upgraded in a healthy state, and then the equipment for road test is installed to collect log information for road test, so as to provide the most accurate vehicle operation information for foreign programmers. Finally, the engine control system is read out through special equipment, and the objective information such as the read program, the log information of the road test, the reasonable needs of the riders, and the oil product of the vehicle configuration are transmitted to the foreign program providers to ensure the rationality of the program optimization.
In fact, brushing ECU is not a simple sense of the control system of high-power models directly copied to low-power, high-power engines still have room for upgrading and expansion, but the size of the expansion space is different. The orthodox program will customize the program according to the actual operating conditions of each vehicle, so as to ensure the pertinence and stability of the program optimization. The early work is to need the authoritative horsepower machine for the relevant models to carry out the data test under the relevant oil products, this early data development takes a long time, in order to come up with the best data baseline, when upgrading each vehicle of the same brand in the same year, the actual vehicle log collection of the car is required, and the optimized data can be fine-tuned according to the characteristics of each car on the stable data baseline, and the optimized data is written into the car after the log collection of the road test again, and the rationality of the optimization of the program is revised, so that the deployment of the program, the operation time cycle is short, stable, more targeted.
Beijing Eisen BMW X3 upgrade ECU actual effect
The overall operation is about three hours, and the customized and optimized program has been implanted into the engine control system, through the special equipment detection, the log information collection of the road test is carried out again, and the rationality of the program optimization is revised;
The actual road test results are summarized as follows:
1: Through the overall customization and optimization, the car can be felt lighter at the start, the acceleration continues to be linear with the acceleration feeling, the previous low-speed and rapid acceleration power lag phenomenon has been improved, and with the expansion of the maximum output speed, the explosive force of the rear end is more powerful;
Two: the shift logic is clearer and smarter, the shift is more positive and smooth, and the overall driving control feeling is very linear with the upgrade of power and handling.
Three: The sound is more deep and deep, and the BMW X3 brush ECU upgrade improves the power to improve the cost performance and safety of gear shifting.
As the saying goes, "motivation is like money in your pocket, you can do without it, but you can't do without". Brushing ECU is currently the most direct, effective, safest and most economical modification method in automotive power modification. The optimization and upgrade of the ECU is to give full play to the more accurate calculation of the car, that is, to accelerate the speed of ECU calculation, after the ECU upgrade, it will only improve the combustion efficiency of the engine, and will not cause any harm to the engine, but also increase the driving pleasure and make the driving more targeted.
