Thrill seekers everywhere have a passion for driving cars. So, understandably, they opt for the characteristics of a sports car such as, BMW models. Some of these models are faster and more powerful models than others. In most cases, it’s not always possible to change the engine or car each time to satisfy your desire to go even faster. However chiptuning engine or chiptuning remains an alternative. Most models are equipped with an electronic box or computer having a series of parameters for the proper operation of the engine. In practice, chiptuning the engine lets you reconfigure the computer map.
How to chiptune the engine of a BMW?
chiptuning the computer begins with a mechanical check that allows the change of the defective parts. Several methods of chiptuning the motor exist:
Chiptuning by generating password:
The computer is removed from the vehicle and then connected to a supercomputer to generate the manufacturer’s password. Once authorized access, a series of engine management parameters (ignition, injection, intake, or pressure on the turbo) are optimized to provide better performance to the car. The chiptuning is then validated via a digital signature of BMW origin. Thus, the operation remains undetectable and mapping is recognized as authentic by the BMW dealer.
Chiptuning via diagnostic test:
This method requires opening of computer and hacking the microprocessor to disable the digital signature of the software. The computer is then reinstalled in the vehicle and chiptuned with personalized motor management parameters via the diagnostic socket. However, the settings remain detectable by the BMW dealer because the date of the last flash will not correspond with that of the last visit to the dealership, which may result in a loss of warranty.
The benefits of chiptuning your BMW engine
Chiptuning allows for an additional power gain between 20% and 50%, with maximum engine torque at a lower engine speed without having to change the engine or the car. Also, the climbs in revs stay more vivid, with more sensation. Fuel consumption is reduced significantly, while still complying with anti-pollution standards.
