RELIABILITY OF THE SERVICE confirmed by the long-term activity of the bmg Tuning brand!

You can verify the quality of available or possible to prepare ECU & TCU files on our website by looking at our BMG TUNING brand. It was the daily activities and thousands of files written for our own implementations and projects that contributed to the idea of building the website. The file modification options available on our platform, both in terms of increasing power, tuning, ecology or other modifications, can be compared to our internal implementations, published on our website and in social media.

The confirmation of these words are the opinions of hundreds of customers, as well as the projects available on our website, which you can read by clicking on both hyperlinks.

Your questions, our answers

How do I order a file on your site?

First, create an account on our platform. Second, prepare the soft you want to undergo a specific modification. Third, send the file, then pay for the order and wait to receive our modified software. To complete this process, you must be logged in and a registered user of our service.

How long will I wait for the file?

As a rule, files are uploaded in just 1h! If you care about time, write to us, communicate the need for an express order, and we will do our best to prepare the software for you in the shortest possible time. As a rule, we do it up to a maximum of 60 minutes! Keep in mind that you can usually count on urgent action during our business hours, from Mon to Fri from 8:00 am to 4:00 pm, but know that in other timeframes we can also respond at an extremely express pace. Just get back to us.

What kind of guarantee do I get from you guys?

All files that we send to our customers are the result of our work and experience collected in the case of internal implementations, so the correctness and effectiveness of their performance is 100%. Custom changes are also not made by chance, so you can rest assured, but if there was a need for correction, we can always correct the uploaded soft if you prove a mistake on our part.

The most important issue affecting the quality of our cooperation and YOUR map is...?

Your knowledge, experience and professionalism, because that’s exactly what our team is.

Remember that the purchase of even the most perfectly prepared file may not be sufficient in your own implementation if you do not have the knowledge and tools to verify the mechanical condition of the vehicle you want to modify. And it doesn’t matter if it’s a power increase, tuning, eco-tuning or environmental modifications.

You need to know that your final satisfaction or that of your customer will largely depend on knowing what you are dealing with. This requires technical and mechanical knowledge, as well as reliability, professionalism and attention to detail in the work performed. If you approach your projects with as much care as we do, then you don’t have to worry about the effectiveness of our files!

The best form of contact with you is...?

Definitely a contact form, email or text message on WhatsUpp! This is the most effective and efficient form of contact, favoring the quality of implementation and its handling time. Instead of calling us, just send us a message, because we don’t always have time for a phone call!

In our service you will find both ECU and TCU files, covering a variety of modifications. You can have us make them from scratch or download ready-made, previously created by us files. Using our services, you can be sure that the files available from us have been prepared in a specialized tuning workshop, verified during our own realizations, both in terms of computer diagnostics, logs of all key parameters and in the case of tuning – also on the dynamometer.

Chiptunig files

Chiptuning files is nothing more than a set of modifications designed to increase the power of a vehicle. Files related to wide-ranging tuning were created by us for each model individually in the form of an individual map. We subjected them to verification on a dynamometer, performed computer diagnostics, analyzed logs and, finally, recorded graphs of the measurements. In this way, we are assured of the quality of the saved modifications assigned to a specific vehicle model, stervo, engine and software version. So you can use our ready-made modifications as well as have us custom file for individual rework and we have no problem with that at all.

Remember that the best results are obtained through a customized approach to each implementation, so the priority on your part will be to subject the vehicle to a meticulous analysis of the technical condition, diagnostics and verification of all key components. Only such measures ensure optimal and guaranteed results at the time!

Tuning files

Files related to car tuning are mainly custom-made (by the way, in the matter of chiptuning it is similar), which should be preceded by meticulous diagnostics and verification of the vehicle’s condition. Ideally, the process of such an analysis should include the scope of work that we perform on our own dynamometer in our internal projects. The ideal scope of work is computer diagnostics, dynamometer measurements and logs of all key parameters.

ADBlue files

AdBlue files are a set of files designed to disable the exhaust gas treatment system with AdBlue urea or in certain cases of reduced urea intake. The AdBlue removal process is a guarantee to get rid of common system-related defects.


DPF and FAP files are software modifications that follow the physical removal of clogged and obstructed particulate filters. Both wet and dry.


EGR files are files that disable the operation of the exhaust gas recirculation valve in all sorts of vehicles.


Software modifications in the physical removal of GPF, OPF and catalytic converters, which are most often part of tuning in terms of increasing the power of the vehicle, as well as to improve the sound of the car.


Deactivation of the Start Stop system, modification of the fuel start rate and other minor changes to the car’s software.
