The payback time of the kit with a working Bosch DeNOx 2.2 Euro 5/6 system is 2 months (standard truck with a range of 500 km / day). And if we talk about repair, then the cost of any sensor will override the cost of the kit.
Even the driver can install the emulator, because the module is connected to the standard car wiring connectors.
The main module is connected instead of the DeNOx 2.2 pump module located in the vehicle frame. One cable is connected to the break of the metering valve (located at the catalyst inlet), the second cable is connected to the cable connector on the NOx sensor.
The waterproof housing and industrial components, as well as high-quality factory assembly, guarantee a 3-year warranty.
