These specifications make WinOLS one of the most advanced ECU tuning software among the competitors. It is also able to show the tables in 2D or 3D views, which helps you to recognize the tables and change parameters via WinOLS. The software helps you to review the dump via an 8-bit or 16-bit data for the required table and make necessary changes as you wish. It’s important to mention that this ability is only applicable to ECU types that have their plugin in the software database. Another attractive capability is that it does the checksum correction after making changes to the file. The Software WinOLS, produced by EVC electronics, has become one of the best tuning software due to its unique capabilities in detecting parameters in the different ECU tables such as the torque limit, fuel injection, spark advance, and also ease of parameter change in ECU file. We will introduce some of the software that has the most application and popularity, meanwhile supporting a wide range of ECU types.

We will select them depending on the type of work we want to do. Each of the software is designed for a specific type of job.

Nowadays, there is plenty of ECU tuning software that companies have brought to the market.

To tune and make changes in the file we need software to be able to change the lookup table values such as fuel, spark advance, turbocharger pressure. In contrast, BMW M-power advanced engines with newer EMS systems have a larger file size, near 4 megabytes which are 15 times larger because these engines have advanced direct fuel injection or GDI, Variable Valve system, turbocharger and etc. This indicates that the ECU controls a simple 4-cylinder engine. As an example, in Bosch MP5 and MP7, the file size is 128 kilobytes or 256 kilobytes which is quite low. In older EMS systems, the engines were simpler and fewer components were controlled by the ECU. The newer and more advanced ECUs have larger file size. The size of the file that is read is different for various ECUs. It is the binary number that is programmed on the flash, It is actually a bin file. The type of the file that has been read from the ECU is of Hexadecimal type.

When you have successfully read the ECU file, you can save the file on a laptop during the final steps of the process.
