In development:
Gasoline values such as lambda, exhaust gas temperature, intake temperature and more
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
