ECU (Electronics Control Unit) stands for electronic control unit. It is the "brain" of the vehicle's engine. It is where the behavior tables are housed, which Reprorace accesses and modifies to achieve power increases and variations in the electronic management of the engine.

Depending on the control unit (ECU) that your vehicle equips, the procedure can be OBD, Bootloader, BDM or Bench.

The most common connection system is OBD, which consists of extracting the original data from the electronic engine unit through the diagnostic connector.

In cases where it is not possible to read by OBD we will use one of the other 3 additional modes which require more time and more sophisticated equipment. All ReproRACE distributors are trained to perform ECU read and write operations.

The ReproRACE switchboard Reprogramming process consists of 3 phases: 

  • The ReproRACE dealer tests the vehicle's operation and extracts the original data from the ECU.
  • The original data read is sent to our central office, where our development department makes the pertinent modifications based on our client's requests.
  • Once the data is modified and made available to our dealer, he will write the modified data back to the vehicle and the vehicle will be ready for testing.

All modifications are always made from our central office in Madrid (Spain).

Offer a standard in quality and benefits. That is why we make sure that all modifications are made in the same way, complying with internal safety regulations. Only our development team is officially trained for this job.

Broadly speaking, we can say that Yes.

There are certain exceptions, especially older vehicles with embedded electronic systems that do not meet standards or without reading ports. Even so, there are a minimum number of vehicles that do not allow us to read. ReproRACE has the most advanced reading and writing equipment on the market.

Logically, the vehicle must be in good mechanical condition. We are not talking about excess mileage, since a vehicle with many kilometers can be programmed without problem.

We can service damaged vehicles as long as the purpose of the programming is to repair a fault.

If your vehicle does not have mechanical modifications, the programming that we must carry out is Stage1.

We recall that Stage2 and Stage3 are electronic calibrations for vehicles with mechanical changes that make it necessary to electronically adapt the new components. The minimum components to make a Stage2 are a high flow intake filter and the elimination of exhaust restrictions (down pipe).

Both are included in Stage1.

It is about determining what is the purpose of the programming so that our developers make the necessary changes to obtain the maximum fuel savings or maximum power.

It should be noted that both EcoRACE and MaxiRACE will get a power boost, although it will be more noticeable in MaxiRACE.

We call OBD reading the reading of the original data that the manufacturer wrote in the ECU through the connection to the diagnostic connector, which all vehicles have installed since 2001, regardless of the brand.

VR reading mode is the system used by vehicle manufacturers when updating the software at the official dealer. They wrote the data, therefore they do not need to do any reading, they simply connect to the vehicle, verify the software calibration and download the file to be modified from the server.

ReproRACE does the same as long as it is available, in order not to manipulate its electronic unit and carry out the work through an OBD connection.

It is necessary to intervene the ECU when we do not have any less invasive reading mode available for data extraction or when we need to read all the memories of the electronic unit to make a data transfer or cloning.
