AcStag App Update to Version 1.0.6
In the AcStag 0.64.2.12703 app, a new firmware version, v1.0.6, has been released for controllers in the STAG 500 GO family. The update introduces new diagnostic features and improvements that enhance user experience and system reliability.
Requirements
To use controllers with firmware v1.0.6, you need the AcStag app, version 0.64 or later.
Key Changes in Version 1.0.6
Diagnostics of the HP Pump Control Circuit
A diagnostic function for the internal high-pressure (HP) pump control circuit has been added, allowing for faster detection of potential malfunctions and simplifying the service process.
New "Maximum Pressure Regulator Temperature" Feature
The software has been expanded to include a new setting:
"Maximum temperature of the reducer"
Once the set temperature threshold is exceeded, the controller will automatically switch to gasoline. This event will be indicated by a sequence of three long beeps.
Once the regulator temperature drops below the set threshold, the controller will automatically switch back to gas supply.
Setting the value to 150°C deactivates the function.
Improved integration with the Start-Stop system
An issue has been resolved in certain vehicles where the engine took longer to restart after the Start-Stop function was activated. This update improves the restart process and enhances the vehicle's comfort.
