Very frequently asked questions about which version of BUDS and what equipment use to diagnose vehicles BRP.

For the diagnosis of 2-stroke vehicles required:

1. MPI-3 adapter.
3. 2-stroke cable.
4. MPI-3 cable.
5. License key for B.U.D.S.

For the diagnosis of 4-stroke  vehicles required:

1. MPI-3 adapter.
2. MPI-3 cable.
3. DESS Post EFI/RFI/DI/4-TEC.  (for add keys for SeaDoo, SkiDoo)
4. License key for B.U.D.S. 

We have developed a DESS 4-TEC, which reduces the cost of equipment for those who do not work with 2-stroke engines.

More information on the use of kits for diagnosis you can get by downloading the file BUDS CHART

This depends on the model of your adapter. Today, there are two models of adapters: MPI-1, MPI-2 and MPI-3

MPI-1 - the old adapter, able to work in three main protocols: KW2000-250k, DESS, 947-DI. Communicates with the computer via RS-232, also called a COM port. It supports almost all models 4-TEC, which support the exchange rate 250k KW2000 protocol as well as the entire line of 2-stroke technology. Due to lack of KW2000 protocol with baud rate 500k is not able to handle E-TEC technology, and some models of ATV Can Am.

MPI-2 and MPI-3 - a modern adapter USB, which uses the protocol CAN, supports transfer rate of 25 to 1000k. For the diagnosis of BRP vehicles used KW2000-250k and KW2000-500k. As a standalone unit, supports vehicles 4-TEC and E-TEC, without the possibility of record keys. With prefix DESS Post is able to register the keys, and is able to serve the full range of vehicles BRP, including old-style, like his younger brother, the MPI-1.

MPI-1 adapter is no longer supported by software.
The latest software B.U.D.S. only works with MPI-2 and MPI-3 adapter.

Chip tuning - is an electronic increase the capacity of vehicle.
Chip tuning refers to changing or modifying an EPROM in vehicle's electronic control unit (ECU) to achieve better performance, whether it is more power, cleaner emissions, or better fuel economy. The engine's manufacturers are generally using a conservative ECU map to allow for individual engine variations as well as infrequent servicing and poor-quality fuel. Vehicles with a remapped ECU may be more sensitive to fuel quality and to schedule of service.
The ECU of modern BRP vehicles, together with advanced engine technology, makes it possible to control many aspects of the engine's operation, such as spark timing and fuel injection. The ECU may also control electronic throttle control (drive-by-wire), valve timing, boost control (in turbocharged engines), speed governor (if equipped).
Modern ECUs of BRP vehicles can be tuned by updating of their software through a standard interface such as MPI-2 adapter or IXXAT adapter. This procedure is commonly referred as "ECU-tuning”.
Performance gains are realized by adjusting the ignition timing advance. Higher timing may result in higher performance. However, to cope with advanced timing, one must run high-octane gasoline to avoid pre-ignition detonation or pinging. Manufacturers design for a specific timing and this may limit performance accordingly.
Most manufacturers of vehicles are customizing their ECU for optimum emissions and fuel economy purposes which can limit performance.
The most common way to 'upgrade' the ECU is using either plug in modules or using a specialist tuner who will use an OBD Flash tool. These devices generally plug into the diagnostic port although in some cases the reprogramming is done directly on the circuit board (opening of ECU, replacing of the chip with EEPROM).
We offer you a way to restore or improve the firmware in ECU (ECM) of your BRP vehicle without opening the housing of the module ECU.
We present to you our software DIUS Flasher 4.0.
DIUS Flasher is primarily intended for advanced users and repair workshops.
DIUS Flasher allows you to restore or replace the standard (default) firmware by another one standard or Tuning-firmware (with improved fuel maps) in ECUs of 4-TEC and E-TEC models of BRP vehicles (SeaDoo, Can Am, SkiDoo).
DIUS Flasher does not offer the ability to change data of firmware (fuel maps, fuel pressure, RPM range, etc.).
The program works in Windows XP SP3 and in Windows 7 with the original adapter IXXAT and with the MPI-2, MPI-3 Interface.
Thanks to the DIUS Flasher 4.0 you can restore or replace the firmware in the models of ECU such as:
  • Siemens VDO MSE 3.7 R/xx (date of manufacture 2004-2017)
  • BOSCH Motronic ME17.8.5..
Manufacture Date of ECU Siemensis listed on the label, as shown below.

The program DIUS Flasher 3.0 is available in several versions: 

  • SeaDoo Edition - unlimited using of all* standard firmware for PWC and Sport Boats SeaDoo.
  • SkiDoo Edition - unlimited using of all* standard firmware for SkiDoo.
  • Can Am Edition - unlimited using of all* standard firmware for ATV, SSV, Roadster Spyder.
  • Repair Edition - unlimited using of all* standard firmware for all 4-TEC/E-TEC BRP vehicles.
  • One File Edition - buyer can purchase one standard firmware or tuning firmware (one firmware can be used to flash only one ECU).

At the moment, two containers of firmware are available for users:

 BRP DIUS Flasher 4.0 STOCK

 BRP DIUS Flasher 4.0 Tunes

Select the container you are interested in and open the list of firmware below.

Please note: you can see the entire list of firmware available for purchase.

After user registration, all firmware counters are set to "0".

If you have already bought any version of DIUS 4 (or you is our customer of any version of DIUS 3), or you already bought

only one firmware DIUS 4 (or several firmware), then expect a message from the dealer that “your firmware or version of

DIUS 4 has been successfully added to your account”.

The ECM Hardware number (HW) is an important parameter of ECM BOSCH Motronic ME17.8.5.

Each firmware (SW) is designed for ECM with a specific Hardware number.

DIUS 3 software allowed ECM programming only with firmware that was designed for the same HW number as the

programmable ECM. Neglect of this restriction led to the failure of the ECM.

DIUS 4 software supports firmware programming for ECMs with a different HW (changing the HW during process).

Currently, in BRP vehicles are used ECMs BOSCH Motronic ME17.8.5 with Hardware numbers 666060-666067.

Depending on the HW numbers of ECM and Firmware, reprogramming of ECM can be done in one or two passes.

ECM Reflash 1 pass is used in the following cases:

  The HW numbers of ECM and Firmware are identical.

  The HW numbers of ECM and Firmware are any of 666060-666062.

ECM Reflash 2 passes is used in the following cases:

  The HW number of ECM is one of 666060-666062, and the HW number of firmware is one of 666063-666067.

  The HW numbers of ECM and Firmware are any of 666063-666067 but not are identical.
