I am seeking an expert developer to design a high-performance WinOLS API system. This system will primarily identify variables, reference version names, and import modifications into the relevant file. The API will access a NAS where all OLS files are stored, identify variables and version names, apply modifications, and send the updated file to clients. The project involves creating an online service with custom frontend accounts for customers. These accounts will use the WinOLS tuning software database (via a custom interface) to apply functionalities to files uploaded by clients. A custom API is required for this operation. The client-facing experience should be seamless, with no indication that the system uses WinOLS. Internally, the system must allow applying scripts from WinOLS, utilizing its tuning features. Our packs' maps should be automatically recognized by WinOLS, enabling modifications as needed, script application, file saving, and original-to-original comparisons (a built-in WinOLS feature). The API must control all necessary WinOLS functionalities. Development can be in Python, C#, or Lua based on the developer's preference. Ideal skills and experience: - Extensive understanding and experience with the WinOLS API - Expertise in ECU data analysis, entry, and importation - Proficiency in Python, C#, or Lua - Ability to deliver robust, efficient code of high quality - Strong attention to detail and problem-solving skills. This project offers a challenging yet rewarding opportunity for developers passionate about programming and analysis. I am looking forward to collaborating with a motivated and experienced developer to make this project a success.

Hi, I’ll develop a custom API-driven platform that connects your NAS-hosted OLS files with a secure client interface, automating ECU file processing through WinOLS. The system will support variable and version identification, map recognition, script execution, modifications, file saving, and original-versus-modified comparisons. I’ll focus on reliable WinOLS integration, efficient file handling, and a clean architecture using Python, C#, or Lua based on API compatibility. A few questions: * Does your WinOLS installation provide an existing API or SDK, and which version are you using? * Should the system run WinOLS on a dedicated Windows server, or do you have another execution environment in mind? * How are tuning packs, map definitions, and modification scripts currently organized on the NAS? Best regards, Muhammad Usman

Hello!⚡ Le défi principal est de créer une API WinOLS capable de gérer l’identification des variables, la gestion des versions et l’importation des modifications sans exposer WinOLS à l’utilisateur final. Le vrai risque est la synchronisation fiable entre l’API et le NAS pour éviter toute perte ou corruption de données lors des modifications. Je propose une solution en Python, qui offre une bonne intégration avec WinOLS via ses scripts LUA et une gestion efficace des fichiers sur NAS. Je commencerai par concevoir une architecture modulaire pour l’API, puis j’implémenterai la détection automatique des variables et versions. Ensuite, je développerai l’interface utilisateur personnalisée pour masquer WinOLS. Enfin, je livrerai un prototype fonctionnel permettant d’importer et d’exporter les fichiers modifiés. J’ai déjà développé une API personnalisée pour un logiciel de réglage ECU avec gestion de versions et scripts intégrés, ce qui correspond au même mode d’échec lié à la cohérence des données. Je propose 650 USD pour l’ensemble du projet, livré en 10 à 14 jours. Ce prix inclut la gestion complète de l’API, l’interface frontale et les tests d’intégration. Toute fonctionnalité additionnelle ou adaptation majeure sera facturée en supplément. Thanks. Hassan

I can build the client-facing service around a clean C# API boundary, with isolated customer accounts, safe file handling, WinOLS script execution, version checks, and original-versus-modified comparisons. I would keep processing queued and auditable so each uploaded OLS file can be tracked and recovered without overwriting the source. Please confirm the licensed WinOLS/OLS530 LUA interface, expected concurrent jobs, and deployment target (Windows service, Linux container, or hosted VM); those determine the integration adapter and storage design. I will deliver the API, account flow, processing pipeline, and a small end-to-end test/demo against your licensed setup.

Hello, I'm Denis, a full-stack developer specializing in custom API systems that integrate specialized software with complex data workflows. I understand your project: you need an API layer between WinOLS and clients, providing a clean interface that abstracts the tuning software complexity. The API must handle file uploads, identify ECU variables and map versions, apply modifications through WinOLS scripts, and manage comparisons—all transparently to end users. I've built similar integrations where specialized tools were wrapped in web services with custom authentication and role-based access. The key challenge is managing reliable communication between your API and WinOLS while handling file I/O and data transformation correctly. My approach: map WinOLS's API functionality, then design a clean abstraction layer in Python or C# handling variable identification, file management, and script execution. The frontend communicates only with your API, never directly with WinOLS. I'd build core file handling and variable parsing first, then layer in scripting and comparison features, with testing focused on data integrity throughout the modification cycle. The main consideration is understanding WinOLS API capabilities and limitations around concurrent file access or script execution. We'd design gracefully to avoid bottlenecks as your user base grows. I'm ready to start immediately. Let's discuss the details. Thanks, Denis.

Bonjour, Je comprends que vous souhaitez construire une API personnalisée autour de WinOLS afin de fournir une interface en ligne indépendante, permettant aux clients de téléverser leurs fichiers, d’identifier les variables et versions, d’appliquer les modifications ou scripts autorisés, puis de récupérer le fichier traité. Je peux concevoir l’architecture avec une API backend en Python ou C#, un système de comptes et de permissions, ainsi qu’une couche d’intégration dédiée à WinOLS. Les fichiers stockés sur le NAS pourront être indexés et associés aux différentes versions, tandis que les opérations de traitement seront exécutées de manière contrôlée avant de retourner le résultat au client. Je porterai une attention particulière à la gestion des fichiers, aux traitements concurrents, à la traçabilité des opérations, aux erreurs et à la sécurité des accès. L’interface pourra également masquer complètement la complexité de WinOLS côté utilisateur tout en exploitant les fonctionnalités disponibles via son interface/API autorisée. Questions : 1. Disposez-vous déjà de la licence WinOLS et de la documentation/API correspondant à votre version ? 2. Quels types de scripts WinOLS doivent être exécutables depuis la plateforme ? 3. Le NAS contient-il déjà une structure organisée des fichiers, versions et packs à exploiter ? Cordialement, Houssame

La partie la plus délicate de ce projet n'est pas de scripter WinOLS - c'est de masquer complètement sa présence côté client tout en gardant l'intégrité des fichiers OLS intacte. Si l'interface personnalisée expose ne serait-ce qu'un message d'erreur natif de WinOLS ou un format de log reconnaissable, l'illusion tombe, donc toute la couche d'erreurs et de logs doit être réécrite, pas juste l'UI. J'ai une expérience directe avec l'API WinOLS et le réglage ECU, donc je construirais cette API comme une couche d'abstraction complète autour de WinOLS - le backend pilote WinOLS en arrière-plan (identification des variables, application de scripts, comparaison original/modifié), pendant que le frontend ne communique jamais directement avec WinOLS, seulement avec cette API intermédiaire. Pour l'accès au NAS où sont stockés les fichiers OLS, je mettrais en place une gestion de verrouillage stricte par fichier pendant le traitement, pour éviter qu'un client ne télécharge une version pendant qu'une modification est encore en cours d'écriture - ça évite les fichiers corrompus, un risque réel avec des accès concurrents sur des fichiers ECU. Pour le langage, je recommande C# pour le contrôle direct de l'API WinOLS (meilleure interopérabilité native avec l'écosystème Windows de WinOLS), avec Python en option pour les scripts d'analyse de variables si besoin.

I’ve built and integrated WinOLS API systems before, handling ECU data parsing, version tracking, and script execution—so this is right in my wheelhouse. I’ll design a Python/C#/LUA API to interface with WinOLS, abstracting the backend while exposing a clean frontend. The system will parse NAS-stored OLS files, resolve variables/versions, apply scripts, and sync changes—all while masking WinOLS from end users. I’ll validate each component before deployment, ensuring seamless script execution and file comparison. I can start immediately. Thanks, Andrii.

Hello, The technical side is straightforward — a Python service watching your NAS, driving WinOLS through its scripting interface, identifying maps and versions, applying your packs, and returning the modified file through a clean front end your customers see instead of WinOLS. Before I quote firmly, one question worth settling: how many WinOLS seats does your licence cover, and does EVC permit multi-user access through an API? That determines whether we build against one installation or a licensed pool, and it changes the architecture completely. I'd rather raise it now than build something that breaks when EVC reviews it. Looking forward to work with you. Thanks

Hi, Mateo here, from Toronto. I'm a full stack developer with 8+ years of experience working with Python, C#, Lua and API Development. I understand you need a custom API layer around WinOLS that can access OLS files on a NAS, identify maps and versions, apply WinOLS scripts/functions, save modified files, and expose the workflow through a separate client-facing interface. The crucial challenge is making the external API reliably control WinOLS while keeping file handling, version mapping, scripts, and concurrent client jobs isolated. My approach: first, define the WinOLS integration boundary and NAS file workflow. Then, build the API/service layer with job tracking, file validation and controlled WinOLS operations. Finally, connect the custom frontend workflow, test map/script application and original-vs-modified comparison, and document deployment and maintenance. I can structure the integration so WinOLS remains an internal processing engine while clients interact only with the custom service interface. Happy to go over the details here in chat and suggest the best approach. Looking forward to hearing from you.

==== Hi - Truong here ==== "WINOLS API + LUA AUTOMATION" - you need a custom service that can work with WinOLS in the background while clients only see your own interface. I’d separate the client portal, API, and WinOLS automation layer so uploaded OLS files can be processed, mapped, modified, scripted, saved, and returned without exposing WinOLS to the customer. The API should also handle file versioning, job status, errors, and NAS access cleanly. Can you provide the WinOLS API/LUA documentation or an example script showing the exact functions you already need automated? Looking forward to work with you.

Hello, I can build a custom API interface for WinOLS that abstracts the underlying system while preserving all functionality, using Python for the bridge between WinOLS and your frontend. I’ve developed a similar system for a client who needed to integrate WinOLS with a custom dashboard—used Python to map WinOLS functions to REST endpoints without exposing the original interface. I’d approach this by creating a Python-based API layer that translates WinOLS commands into clean HTTP endpoints, then adding user authentication and file handling logic. The biggest challenge will be mapping WinOLS’s scripting system to a structured API response format. This setup will let you build a frontend without requiring users to know WinOLS, while still supporting all its features. Proper abstraction will reduce errors by hiding WinOLS’s complexity behind a consistent API contract. Once complete, I’ll document the API endpoints and provide a sample integration script to get you started. If this approach aligns with your needs, I’d be happy to discuss the project in more detail. Thanks, Lazar.
