DPF monitoring

The DPF screen is the core Alfa Dashboard function: it lets you monitor diesel particulate filter status in real time, recognise active regeneration and understand when it is better not to switch the engine off.

  • DPF %: central indicator of the estimated soot load/filter saturation.
  • Gas Temp.: exhaust gas temperature; one of the main values used to recognise regeneration.
  • Diff. Press.: DPF differential pressure, expressed in mbar, useful to evaluate filter backpressure.
  • Regen. Time: duration of the current regeneration, shown in minutes and seconds.
  • Last Regen.: distance travelled since the last completed regeneration.
  • Bottom bar: graphic progress/reading indicator for the DPF cycle, useful for quick reading without checking all numeric values.

During regeneration the firmware displays the “regeneration in progress / do not switch off” warning. DPF temperature is highlighted using colour thresholds: up to about 300 °C stable/low reading, from 301 to 505 °C orange, above 505 °C red with stronger visual emphasis. If audio feedback is enabled, the firmware can alert the user when relevant DPF thresholds are reached.

Info DPF

The DPF Info pop-up shows historical filter data and helps evaluate regeneration behaviour over time.

  • Distance since DPF replacement: kilometres recorded by the ECU since replacement or DPF reference reset.
  • Average distance between regenerations: average kilometres between one regeneration and the next.
  • Total regenerations: total number of recorded regenerations.
  • Interrupted regenerations: number of incomplete regenerations, useful to understand whether the car is often switched off during the cycle.

An increase in interrupted regenerations or a very low average distance between regenerations may indicate heavy city use, incomplete cycles or conditions that should be checked with deeper diagnostics.

EGR and air management

The EGR screen shows the main parameters related to exhaust gas recirculation and air flow. It is useful to check the actual valve opening, the command requested by the ECU and the intake behaviour.

  • EGR Ap %: EGR valve opening.
  • EGR meas.: measured value.
  • EGR cmd.: value commanded by the ECU.
  • Throttle: throttle / air actuator position.
  • Air mass: intake air mass, expressed in mg/c.

Performance, DNA and engine parameters

The Performance screen groups the most useful dynamic driving parameters. It is designed for quick reading of DNA mode, gear, turbo boost, torque and key temperatures.

  • DNA: shows the d / n / a driving mode and highlights the active one.
  • Gear: gear detected by the gearbox.
  • Boost: turbo pressure in bar
  • Torque: engine torque in Nm, with a lower graphic bar for immediate reading.
  • Oil Pump: oil pump status, for example High Press or Low Press, with colour highlighting.
  • AT8 Oil: automatic AT8 gearbox oil temperature.
  • Refrig.: engine coolant temperature.
  • Turbo Air: intake/turbo air temperature.

The screen is optimized for fast reading: the central value gives an immediate view of the selected gear even in automatic gearbox mode, while the side parameters complete the engine/gearbox picture. Animations and graphic bars make load changes easier to perceive.

IBS battery and Start&Stop

The Battery screen shows the IBS system status and the main electrical parameters. It is designed to quickly check charge level and the status of related systems.

  • IBS %: central battery status indication.
  • Volt: real-time battery voltage.
  • Start&Stop: active/inactive status.
  • Status icons for related functions, such as heated rear window/mirrors when available.

Inject

The Inject page is dedicated to monitoring injection parameters. It allows you to keep injector corrections under control and get an immediate reading of cylinder behavior while the engine is running.

  • Cylinder corrections: displays the correction values for each injector, useful for comparing the balance between cylinders.
  • Real-time reading: values are updated during OBD polling, based on the PIDs configured in the firmware.
  • Bar graph: makes it easy to quickly identify any differences between cylinders without relying only on numeric values.
  • Preventive diagnostics: helps identify abnormal behavior that should be further checked with professional diagnostic tools.

The displayed values are indicative and depend on the ECU response, vehicle model and supported PIDs. This page does not replace professional diagnostics: any abnormal values should always be verified with dedicated tools.

  • Beep feedback UI: enables or disables the confirmation sound for button presses/interactions.
  • Audio output: selects the audio output, for example Off, passive Buzzer or Speaker/active buzzer, depending on the installed hardware.
  • Automatic hibernation: enables automatic device shutdown when the vehicle is turned off, useful on cars that keep the USB powered when the ignition is off.
  • Vehicle year: Pre 2020 / Post 2020 selection, used to adapt logic and parameter layout, especially in the Battery/IBS section.
  • Auto DPF Screen: can automatically switch to the DPF screen during regeneration or when the configured threshold is reached, so the user immediately sees the “do not switch off” warning.
  • Auto-return after regeneration: when enabled, after regeneration ends the firmware automatically returns to the previous or configured screen.

Available items may vary slightly between stable and beta firmware. Settings are saved in the device preferences and reused on following startups.
