What is ecu-remapping?

Ecu remapping generally is reprogramming the "brain" of the car for better performance.

As producers have to consider many different conditions and factors like temperature, air pressure, fuel quality (not every country has high octane fuel), the programming of the ecu software often is a compromise between performance and street legality in all countires..
Also the software is made to make the car run even under “unreal” conditions, that normally will never occur in your areas.

These factors still leave the possibility to optimize the factory setup. And this is what TD Performance is specialized in. We can help you to make impressive performance gains without influencing your cars reliability.

For doing this improvement, the ECU of your car need to be reprogrammed / modified.
There are different ways to do this:

- direct programming of the chip (eprom) in the ECU

The eprom must be desoldered from the circuit board. Then it will be erased and reprogrammed with the modified and optimized data.

- OBD-programming

Many new cars offer the possibility to read and write the complete ECU data via the diagnosis connector of the car. The advantage of this method is that the ECU can stay inside the car and needs not to be opened.

- serial programming

The ECU must be removed from the car and is programmed by special spring contacts without soldering on the circuit board. This method is used for example if a car has no connection from the OBD connector to the ECU or  for very new ECU versions. The best tool for this is the BDM 100

Which way of programming is used, depends on manufacturer, model, year and the ECU type in the car. Generally we use the “easiest” way of programming. So if a car can be programmed by the OBD port, we will do it this way.
As we still keep on investing in the latest programming tools and software, you can be sure you get the best results from our work.
