Changelog

v3.8.0 from October 17, 2025

🚀 New

  • M3 S65 engine added
  • Speedometer needle test (needle sweep) implemented
    - Currently available for: M47, N57, N46, N55
    ⚠️ Note: No liability for incorrect engine configuration or non-original speedometer.
    Please check that the correct motor is selected before activating Needle Sweep!
  • Slow lightening/darkening
    - When the display is turned up and down
    - In the setup wizard
  • Battery voltage for vehicles before 2007 (M47, M57, N46, TBC )
  • New measurements for gasoline engines
    - Lambda, exhaust temperature, ignition angle, throttle valve, intake temperature, etc.
    - N46 fully implemented – more engines to follow (TBC)
  • Cruise control (only active when cruise control is not active)
  • Lateral and longitudinal acceleration reactivated
    - Scaled to -10 (−1.0 g) to +10 (+1.0 g)
  • New look: BMW Orange
  • New update website
  • Transmission oil temperature added
    Tested: 6HP , DKG TBC

🛠️ Improved

  • Read Errors / Clear Errors : Increased distance between actions
  • Irrelevant values ​​for the selected engine type are automatically hidden
    - (e.g. ignition angle in diesel engines)
  • Icons visually revised
  • Display: “C°” changed to “°C”
  • Presentation: General layout revised

🐞 Fixed

  • N47: Intake temperature and soot mass errors fixed
  • Error reading: Now works reliably
  • Time measurement:
    Values ​​are reset when the measurement is aborted
    - Incorrect calculation of the 0–100 km/h time corrected
  • WIFI: Connection can now be re-established multiple times, even after switching off

🔧 In Development (TBC)

  • Extension of the petrol values ​​to other engines
  • Battery voltage for additional models
  • Transmission oil temperature support for DKG

v3.8.0 vom 17.10.2025

  • Auswahl S65 für ggf. zukünftige Upates
  • Needle Sweep (wieder verfügbar in v3.8.2)
  • Langsames Aufhellen/Abdunkeln
    - Beim Hoch- und Runterfahren des Displays
    - Beim Einrichtungsassistenten
  • Batteriespannung für Fahrzeuge vor 2007 (M47, M57, N46, TBC)
  • Neue Messwerte für Benziner
    - Lambda, Abgastemperatur, Zündwinkel, Drosselklappe, Ansaugtemperatur usw.
    - N46 vollständig implementiert – weitere Motoren folgen (TBC)
  • Tempomatsteuerung (nur aktiv, wenn kein Tempomat aktiv ist, bald auch deaktivierbar)
  • Quer- und Längsbeschleunigung wieder aktiviert
    - Skaliert auf -10 (−1.0 g) bis +10 (+1.0 g)
  • Neuer Look: BMW Orange
  • Neue Update-Webseite
  • Getriebeöltemperatur hinzugefügt
    Getestet: 6HP, DKG TBC

Verbessert

  • Read Errors / Clear Errors: Abstand zwischen den Aktionen vergrößert
  • Unrelevante Werte für den gewählten Motortyp werden automatisch ausgeblendet
    - (z. B. Zündwinkel bei Dieselmotoren)
  • Icons optisch überarbeitet
  • Darstellung: „C°“ in „°C“ geändert
  • Darstellung: Allgemeines Layout überarbeitet

Behoben

  • N47: Fehler bei Ansaugtemperatur und Rußmasse behoben
  • Fehlerauslese: Funktioniert nun zuverlässig
  • Zeitmessung:
    Werte werden beim Abbruch der Messung zurückgesetzt
    - Fehlerhafte Berechnung der 0–100 km/h Zeit korrigiert
  • WIFI: Verbindung kann nun mehrfach neu aufgebaut werden, auch nach vorherigem Ausschalten

v3.7.2 from September 26, 2025

  • Reading and deleting errors no longer causes any fake errors
  • As soon as voltage is applied, there is a short wait before the display boots up
  • Debug functions removed
  • Inactive Canbus monitoring completely removed

v3.7.1 from September 24, 2025

  • The selected motor was not saved in the setup wizard, which is why values ​​did not work

v3.7.0 from September 23, 2025

  • NEW: Setup wizard (reset possible in the settings)
  • NEW: Read and delete DME/DDE errors
  • Three times faster query of engine data such as boost pressure, lambda or exhaust gas temperature
  • Display switches off at 0 rpm
  • Fixed automatic brightness on boot
  • Petrol engine: Final preparations for querying the missing values
  • Firmware update is now displayed better
  • Many more logic corrections
