POWER UNLEASHED !!
The VAITRIX team consists of some of the most professional performance tuners and engineers from around the world.
When it comes to remapping, there are multiple ways to read the data required to tune the Engine/Electronic Control Unit ECU. The ECU is a computer that powers your car and stores a file which contains all of the maps which we require to add more power to further refine your car. There are three main methods for connecting to the ECU, either through the OBD port, by ECU bench, or in boot mode, but what do these terms actually mean?
What is a dyno and what is it used for? A dyno is a piece of equipment/tool for measuring power output at the wheels of a car. Different dynos measure power in different ways. Some will give a figure of power at the wheels, others will use the deceleration of the car to measure the losses through the drivetrain and estimate the power at the engine's crank. Also, a number of factors that will affect the measured output and performance of the car such as the temperature, the humidity, and the cooling method to name just a few. A dyno should be used when developing a tune for the first time. It is a good way of taking a measurement that you can then compare against the next run until you are satisfied with all of the changes you have made.
Working on the bench is the term used for taking an ECU from the car and connecting directly to the pins the car's loom would normally plug into. For this, you require an external power source and a boot cable. You connect power to multiple pins along with a ground and other forms of communication such as CAN+ and CAN- or KLine. This is also known as working in service mode as it is the method used by the manufacturers such as Bosch and you are typically able to read the full memory storage.
Boot reading and writing is again work done on the bench and it is perhaps the most technical looking as it requires opening of the ECU and connecting pins directly to the chipboard. The basic principles are the same as in service mode, you connect directly to the connection pins. However, in order to bypass the security chip, you have to connect boot or earth pins directly to the board. You are then able to read and write the full memory, working around the TRICORE protection found on a wide range of Bosch (M)EDC17. Boot mode is often the first option to come to market when a new hardware solution is developed as from a developer's perspective, it is the first step in discovering all of the protocols and blocks contained within the ECU.
OBD (On-Board Diagnostic) reading and writing is perhaps the most common and popular tuning method. It has revolutionised the industry, making the accessibility of tuning available to a wider audience. It is used to gain access to the ECU from within the vehicle. It is often located under the steering wheel or around the glove box. It is designed to allow for fast and easy fault diagnostics to assist mechanics with finding problems by scanning the ECU for codes. Some cars allow you to take full data reads though the OBD and others will only allow for a partial read. In some newer cars, the software is locked so some tools offer VR (Virtual Read) files which are essentially original files stored on a server that match the software version within the ECU. The tool is then able to bypass the tuning protection and write your modified version of the file. When tuning a car through the OBD, you have to be mindful of the vehicle's battery strength as a break in communication due to low voltage can cause serious errors.
TUNING BY EVC WINOLS
When working on a car, the first thing we need to do is read the original file from the car. Once a file has been read, it is time to open it up in a map editor, the most popular is WinOLS. The file itself is nothing more than a collection of numbers, stored in binary format. The numbers would make no sense if you were looking at them for the first time and this is where the specialist knowledge comes in. In order to work on a file you must define all of the maps you require, for editing and reference. We then work our magic, optimising and adapting the software in order to unlock the hidden power of your car.
A good stage 1 file is designed in a way such that it works with all of the standard hardware. At stage 1, there is no need to push any of the limitations because the aim is to work with the standard hardware and merely improve it. So if you are working on two different cars with exactly the same engine and ECU software, the changes you make on one will be the same as the next car for a stage 1 tune. But both files are made from scratch with the software version read from your car so both are technically custom. Each tuner will build their tune the same way. We can retrieve the tuned file or we could push it a little further to suit a customer's needs and driving style.
ECM TITANIUM TRAINING
ECM TITANIUM is a remapping software that allows you to view and write the maps of any original engine and transmission control unit files.
Each map has precise instructions that can be interpreted, modified, and made perfect, thanks to the remapping software.
VAITRIX can perform, with the best tools and equipment, to bring the desired results.
