Brush ecu need to know the 12 questions
Each vehicle engines, like people, if given proper exercise and proper external conditions, in which the body potential can be realized. For automobile, it must be a car to find a balance in all aspects of energy consumption, reliability, comfort, cost, etc., and therefore will not play all the potential of the engine, it also gives a lot of the pursuit of power consumption by modification of leeway in the future.
Brush ECU, the technology more used to improve F1 racing and rally, depending on the track to improve engine power output in order to improve the car performance. In fact, for many drivers this civilian-level family car riders, still a novelty. The engine, the car ECU is equivalent to the relationship between computer software and hardware, should be more appropriate analogy, automotive ECU is equivalent to the computer BIOS on the motherboard through which can regulate the engine power output values.
1, brush ECU (ECU upgrade) What are the benefits?
Overall, the power increase of 8% -36%, 5% to 25% lower fuel consumption, reduced exhaust emissions.
A. horsepower naturally aspirated models increase of about 10%;
B.TURBO models to increase horsepower by 20% -30% or even more;
C. When shifting more smooth, dynamic convergence even better;
D. factory can not solve many problems, such as: easy to turn off idling too low, the transmission shift shock problem.

2, so why not the original car factory design?
The electronic control unit called ECU (Electrical Control Unit) which manufacturers are international multinational corporations, such as: BOSCH, SIEMENS, MM ...... production and sales of products to countries around the world use. Each country due to differences in the quality of gasoline, temperature, barometric pressure, humidity, engine form shall comply with the ECU software to set the conditions of each country to use, so as not acclimatized, plus must be durable, economic, and environmental protection multi-condition, so the original car computer more conservative set the scope, so reserve some space for retrofit upgrades.
3, after the upgrade would not affect the life and safety of the vehicle?
After the upgrade will not affect the life of the vehicle and safety, the reason is very simple, just brush ECU ECU and automotive engine optimization parameters, rather than letting the engine work in the limit state, optimization is built on the basis of ensuring the safety of life and carried out, but also to retain the absolute safe space, it will not affect the car's safety and service life.
4, the performance of the car's engine enhancements will hurt it?
ECU program to rewrite the destination, the optimization engine is running, to improve fuel combustion efficiency, so the engine will not have any harm, even in the running of the new car can be modified.

5, will fuel after ECU upgrade?
Control ECU upgrades are not a multi-injection to increase the horsepower, but fuel supply and ignition curve adjustment and re-match by computer optimum mix of air and fuel in accordance with the external sensor signal and engine valve lift and timing to achieve the purpose of increasing the horsepower output. Most upgrade customer response said the car will run more, but also fuel-efficient than the original, I feel very good!
6, how life after ECU upgrade?
For a majority of European models, can now read and write to complete the upgrade process data via OBD II diagnostic interface, only a small part of the need to disassemble the computer for processing. Application of the most advanced technology to ensure the integrity of the ECU, the computer will not be demolished in the future development direction of a tuned ECU. With respect to moving the solder under the chip to perform the upgrade process, and more secure. Just finished upgrading ECU without external damage, used car scrapped ECU is still available.
7. What is the upgrade process?
Read the engine ECU chip data, according to the driver's intentions, combined with local climatic conditions, the oil situation, the European (Italy, Germany), senior adjust one on one service. Currently the most cutting-edge technology is the way to avoid demolition computer, this upgrade mainly through OBD2 interface to read and write data, mode of operation and the safety factor compared to the traditional way of demolition chip considerable progress.
8, if unable to return to work after you upgrade the original computer to diagnose or failure? Are security systems function will be lost?
ECU upgrade, fully tailored approach to take, after reading the original car program under the original transfer from the car information required in accordance with the customer and only for the power part of the program be adjusted. Then return to install the upgrade program, it will not affect other functions of the original car, the original car any electronic system will be retained, including the original car based on the installation of electronic equipment such as: GPS, DVD, etc., but the original diagnosis fault code on the computer will not be unable to eliminate the appearance of relative security systems also will remain.
9, the same model modified ECU upgrade program is only one of each model it?
No, to AUDI A6L 2.0TFSI example, so far we have found this version of the model five computers, and this distinction differentiated hardware number, software number are different, the difference number of the software is divided into the same number of hardware and number of different hardware, and automotive manufacturers to protect their software often have complex computer plus self-checking, so the new car set-up is far greater than the difficulty of some of the old wide models. We are based on the vehicle ECU label on the computer case to row modifications and upgrades accurate ECU program.

10. What is the real meaning of a computer chip is an upgrade?
Currently without affecting fuel consumption (according to the owner to use that "fuel" is another advantage of the largest and most obvious) does not affect the return to factory warranty does not affect the overall dynamic performance improvement under the premise of cars examined, we know; mechanical modifications to a certain extent if the computer is not upgraded, the product is not going to change its maximum effectiveness, such as we change the exhaust pipe of a horsepower increase of 6, but may reach 10 after the computer upgrades, that upgrade added value PCs.
11, how to ECU working environment?
A: The operating voltage range ECU in 6.5V-16V, operating current of 0.015A-0.1A, can withstand the shock of 1000 Hz or less, operating temperature -40 ℃ to 80 ℃. Therefore, ECU failure rate is very small.
In fact, this project is mainly brush ECU from abroad, originated in the racing program, then gradually be applied to the family car, and widely popular. China is still in its initial state, many cities have not yet arisen.
12, car brush ECU technical analysis, methods and tools
About step brush, now there are two more common, in fact, there are three, but the first one is outdated, need iron to replace the original eprom, too much trouble has been almost eliminated. There are two methods to upgrade the current left,
One is through the obd interface directly connected to the car's diagnostic port to read and write data.
This method uses equipment produced by German ielec byteshooter, CMD (commonly known as the most expensive equipment), as well as Italian production KESS V2 (model upgrade faster)
The advantage of this approach is that without disassembling ECU, saving time and effort. But the downside is that we must ensure the stability of the voltage, or prone to interruption in read and write times.
The second method is the BDM way.
This method uses the device is produced by the German evc bdm100 equipment, as well as the now popular with ktag, there is now the latest model of the device.
The disadvantage is the need to dismantle ECU, relatively time consuming. Most domestic manufacturers should be used in these sets of equipment it. There are other devices, but these sets of equipment is relatively common in Germany, but also the country with the majority. But their prices are not cheap, relatively speaking, a single set in the above 20,000 RMB.
