Added DiagBox 9.268.

What's New:
Support for the latest SGW (Security Gateway) architecture: On newer platforms (Peugeot 308 III, 408, Opel Astra L), older software versions often crashed with a communication error or displayed an “unknown ECU” message. Version 9.268 correctly identifies new ECU types and the secure gateway architecture. It displays parameters and errors, but immediately warns the user if the SGW is blocking writes.
Database for e-DCS6 hybrids and Euro 6.4 engines: The software now includes parameter tables for the latest mild hybrids (MHEV) with a new automated manual transmission featuring a built-in electric motor (Punch Powertrain’s e-DCS6 transmission) and the latest generation of updated 1.2 PureTech three-cylinder engines.

Ajout de DiagBox 9.268.

Quoi de neuf:
Prise en charge de la dernière architecture SGW (Security Gateway) : sur les plateformes récentes (Peugeot 308 III, 408, Opel Astra L), les versions logicielles antérieures présentaient souvent des erreurs de communication ou affichaient le message « ECU inconnu ». La version 9.268 identifie correctement les nouveaux types d’ECU et l’architecture de la passerelle de sécurité. Elle affiche les paramètres et les erreurs, et avertit immédiatement l’utilisateur si la passerelle de sécurité bloque les écritures.
Base de données pour les hybrides e-DCS6 et les moteurs Euro 6.4 : le logiciel inclut désormais des tables de paramètres pour les derniers hybrides légers (MHEV) avec une nouvelle transmission manuelle automatisée dotée d'un moteur électrique intégré (transmission e-DCS6 de Punch Powertrain) et la dernière génération de moteurs trois cylindres 1.2 PureTech mis à jour.
