Tuning File Portal

Click HERE logo to access the DC Tuning file portal. Registered agents can check here for vehicle stats, load original and downlaod modified files.

If you have any questions about anything we do or have a product enquiry, please do get in touch.

We are  seeing a huge demand for vehicle tuning over the last few months, and have now teamed up with some of the worlds best tuning file writers.

This means when we receive your original file uploaded to our file portal, we have the options to send your files to be tuned by the best relevant file writer for that vehicle.

What is vehicle ECU tuning?

Vehicle ECU Tuning is a process that involves modifying the files & parameters that are stored in a vehicle ECU from new at the factory. The vehicle ECU has a large table of data parameters which it uses to make real time adjustments as the engine is running.

By tweaking the parameters in the a vehicles ECU we update the engine's computer software allowing more flexibility within normal operation of the engine.

This is done by simply connecting our tuning equipment to the diagnostics port fitted to the vehicle or in many newer vehicle cases we remove the ECU and pinout on the bench. We take a copy of the original file, then our experts tweak the parameters to your specification. We then re-write the new files back in to the vehicle ECU via the same method. Basically you will perform a software upgrade to your vehicles ECU. Nothing more! We always keep your vehicles original file should you wish to revert back in the future, although this is almost unheard of!!

Why don't manufacturers perform Vehicle ECU Tuning?

There are several reasons that manufacturers don't supply the vehicle already maximised as far as performance & economy goes.

Primarily, manufacturers focus mainly on reliability. Some people look after their vehicles by regularly servicing them, some don't do anything other than put fuel in. Manufacturers prefer to lean on the side of safety and supply their vehicle in a less than optimal tune, as the chances of it lasting longer are increased. This can then mean that the manufacturer gets a reputation for reliability.

The other is that manufacturers often have a range of vehicles, the more powerful vehicles in the range are usually more expensive. Manufacturers have been known to stifle the performance of engines to make sure that there is a clear difference in power as you step up the range. In many cases you can buy a cheaper version of the car or van and then remap it to equal or beat the next model up in the range.

We stock Dimsport & Autotuner which are two of the worlds biggest and best when it comes to tuning solutions.

Slaved to our sister company DC Tuning Files the New Genius is the stand alone device for the serial communication with the Engine Control Unit (ECU),through the vehicle OBDII socket or via specific diagnostic connectors. It does not require connections to a personal computers or laptop for the management of the serial communication: it has never been so simple and immediate to achieve programming operations of the vehicle stock ECU.

Intuitive operations to maximize the ease of use: New Genius is a true asset for every tuner thanks to the impossibility to perform wrong operations. Detailed instructions appear on the screen and drive the tuner until the vehicle is programmed.


Slaved to our sister company DC Tuning Files the New Trasdata is a unique tool supporting all microprocessors utilized by any kind of vehicles, for reading and programming operations in BDM, BOOT, JTAG, NBD, BAM and GPT mode.When the ECU microprocessor (CPU) is provided by “anti-tuning” feature, a software patch realised by New Trasdata unlocks the OBDII communication, which is therefore restored and supported.


Specific functions conceived for the tuning field like the mentioned reading of the whole ECU firmware, or the self-identification of the engine maps and important additional parameters (even if located in different components of the ECU),confirm New Trasdata as the leading tool available today on the market for reading and programming bench operations.One tool - available in both master and slave versions - to support all microprocessors in the automotive field.


Slaved to our sister company DC Tuning Files Autotuner is a universal tool able to read information from most ECUs and microcontrollers available on the market in boot tricore Infineon (BSL), in bench or via the OBD diagnostic socket.

Autotuner is being constantly improved with new reading protocols. You can freely benefit from it as soon as you start your Autotuner Software.

Ultra-fast process - Ultra-fast, intuitive and powerful ECU programming tool.Compatible with thousands of vehicles

Thanks to the ECU communication optimization and its Cortex m3 processor, memory content (Dflash, Eflash and EEprom) reading is ultra-fast. It then systematically performs a backup of the TriCore password online.

Specific help section is available in the software

Autotuner helps you locate the ECU or OBD diagnostic socket on the vehicle.

It then guides you step by step through the process of reading and illustrates each step with high-definition photos.
