Currently, there is no option to program modify the SID321 controller, which is included in engines manufactured by Continental. As a result, it is not possible to remove support for the AdBlue system by changing the software. To solve this problem, we have developed an SCR system emulator that can be used in Opel Movano vans equipped with engines with this controller.
How does the SCR emulator for the SID321 driver for Opel Movano work?
Our emulator is a small electronic device connected to the communication line of the emission reduction system (CANBUS). The emulator mimics (emulates) the functioning and characteristics of a properly operating SCR system, and then transmits this information to the engine controller. Thanks to this, the controller does not switch on the power limitation mode and does not signal any system errors.
By carrying out computer diagnostics of the Opel Movano car with the SID321 controller and the emulator designed especially for this model, you can observe the operating parameters of the AdBlue dosing system exactly the same as in the efficient car system without the emulator.
Full diagnostics instead of constant error reset
90% of similar devices on the market operate on the principle of continuous debugging of detected errors. Although this may seem like an effective solution, it actually makes vehicle diagnostics more difficult. It can also lead to serious failures, because serious errors affecting the safety of engine operation, such as incorrect oil pressure or turbocharger temperature, are also removed.
Our company focused on innovation by creating a solution in the form of an emulator for Opel Movano cars, which only simulates the operation of a properly functioning SCR system. Thanks to this, even in the case of a damaged system, the car does not report any errors, and the limits of torque, power loss and speed are eliminated.
In addition, thanks to the work of our emulator, the vehicle is fully diagnosticable and can report other errors if necessary.
SID321 emulator installation in Opel Movano
Thanks to our experience and knowledge, we have managed to create a device whose installation is extremely simple and consists only of connecting one plug. To install the emulator, simply disconnect the plugs from the NOx sensors, smoke sensors and the SCR pump. Then, in place of the second NOx sensor, connect the plug from the emulator.
If before the installation of the emulator the vehicle’s power was already limited or the engine cannot be started, the errors should be deleted or the AdBlue system should be restored to its original state. For Opel Movano cars with no power reduction, the emulator can be installed without having to adapt the SCR system.
