INTRODUCTION


Chip tuning - is an electronic increase the capacity of vehicle.

Chip tuning refers to changing or modifying an EEPROM 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 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).

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.
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 by using 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).

The modern ECU of BRP vehicles can be tuned by updating of their software through a standard interface such as MPI-2/3 or IXXAT. This procedure is commonly referred as "ECU-tuning”.

 

 


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.

 

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 on Windows XP SP3 and newest with the original adapter IXXAT and with the MPI-2/3 Interface.

Thanks to the DIUS Flasher you can restore or replace the firmware in the models of ECU such as:

  • Siemens VDO MSE 3.7 R/xx (date of manufacture since 2005)
  • BOSCH Motronic ME17.8.5..

Manufacture Date of ECU Siemens VDO MSE 3.7 is listed on the label, as shown below.
 

 
The program DIUS Flasher 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).
  • DIUS Flasher Full - unlimited using of all* standard and tuning firmware which are currently available in the program's database.

* - The list of all firmware which are currently available in the program database can be downloaded here.

Why do I need it?
What is this program for?

 

 


 

Let's consider a few examples.

Example 1 "Failed Update"

From time to time BRP produces software updates to their vehicles.

These updates may be installed in the ECM by using the program BUDS. During the update process erases old and installs the new firmware.

But not always the process of updating ECU may complete successfully. For various reasons during the update an error can occur: ECU stops responding, and its further use will be  impossible.

In such cases, the program DIUS Flasher may help you** to restore the old firmware (if inside ECU nothing is burned out) and then you'll be able to try update ECU again.

Example 2 "Burned ECU"

Let's assume that the ECU (ECM) of your 4-TEC/E-TEC vehicle "burned".

The vehicle is not working at all or not comes some signal from the module ECU: pulse to the ignition coil, the signal to the fuel injector, the voltage to the fuel pump or any other signal, the lack of which affects the performance of the vehicle as a whole.

What you need to do?

ECU needs to be replaced.

This is good if you can buy a used ECU from the same model as your. If you do not have this possibility you will have to buy a new module.

But new module ECU - it's very expensive! Some models cost more than $ 1,000.

DIUS Flasher will help you to save your money!**

So, you can buy any relatively inexpensive used ECU (in working condition) corresponding *** for your vehicle type (PWC, ATV, etc.) and firmware for your model.

Just follow these few simple steps:

  • Install ECU into your vehicle.
  • Using MPI-2/3 Interface and Diagnostics cable connect the vehicle to the computer.
  • Run DIUS Flasher.
  • Select needed firmware and confirm your selection.

After 3-5 minutes, the selected firmware will be transferred to the ECU.

  • In the program BUDS make reset of the throttle position and reset errors.
  • Using DESS Post Interface add keys DESS.

Is ready, enjoy!

Example 3 "GTI 130 HP + new firmware = GTI 155 HP"

Try to compare the Engine Technical Specifications of two models:

  • GTI™ SE 130 and GTI™ SE 155 2008 here.
  • GTI™ SE 130 and GTI™ SE 155 2009 here.
  • GTI™ SE 130 and GTI™ SE 155 2010 here.

Do you see any difference, except for the engine power?

All engine parameters are identical!

In all of these models are used the same injectors 42lb p/n 420874430.

The question arises: Where then is taken the difference in engine power?

The answer is very simple: In fuel maps which are programed in the firmware!

In the ECU Siemens of models 130 HP such as listed below is used a firmware 420665357.

2008 2009 2010 2011

GTI 130
 
GTI 130 Rental, 1503 DT
GTI 130 and Rental, 1503 DT
 

GTS Pro 130 (1503 DT)
 

GTI Rental 130
 
GTI 130, 1503 DT
GTI SE 130, 1503 DT
 
 

GTI SE 130
 
GTI SE 130, 1503 DT    

 

In the ECU Siemens of models 155 HP such as listed below is used a firmware 420665783.

 

2008 2009 2010

GTI SE 155
 

GTI SE 155, 1503 NA
 

GTI SE 155, 1503 NA
 

GTX 155
 

GTX 155,1503
 

Wake 155,1503 NA
 

RXP 155
 

Wake 155,1503 NA
 
 

WAKE 155
 
   

 

If in the ECU Siemens of these models 130 HP will be programed firmware 420665783 which is used in models 155 HP , then you would have received an additional 25 HP without alteration of the engine!

 

 

 

The article is in development. Come back to us after a while.

 

** -The ability to use DIUS Flasher assumes that you have an adapter IXXAT or MPI-2/3 Interface with diagnostic cable. Necessary equipment can be purchased with one of the multiple versions of DIUS Flasher or separately.

 

***  - the ECU Siemens VDO from PWC (determined by the hardware number) is the most complete (the presence of all the electronic components in the scheme) and is universal. This ECU can also be used on other types of vehicles: ATV, SSV, SkiDoo, Roadster. The rest can only be used in vehicles for which they are intended. If you doubt the choice of ECU, do not hesitate to consult with us.
