ECU Tuning Files Database | WinOLS Projects, Original ECU Files & DAMOS / A2L
Cars • Trucks • Agriculture • Marine • Motorbikes | AI Search | ORI vs MOD Compare | WinOLS Lab
Open ECU Tuning Cloud — bnu.to
Premium: €1,000 One-Time Payment | Lifetime Access | 30 Downloads / 24 Hours
A growing multi-terabyte ECU / TCU firmware cloud built for real tuning work. Find original and modified files, inspect ECU information, compare ORI and MOD binaries, search DAMOS / A2L and WinOLS material, and work with cloud-connected tools — all from one platform.
Important update — October 2026
I previously considered closing Cloud registration and publishing modifications as individual products in the Tuning Files section. After reconsidering the amount of material and the way people actually use the database, I decided to keep the Cloud as the main project instead of splitting it into a huge number of separate listings.
I have also simplified Premium access:
- New price: €1,000 one time (previously €1,500)
- New limit: 30 Trust Firmware downloads per 24 hours
- Payment: cryptocurrency or direct transfer to a bank card, where supported
- Lifetime Premium access — no monthly or yearly subscription
The Cloud remains online, continues to grow, and registration is available through Google sign-in.
What is ECU Tuning Cloud?
This is not just a folder of unnamed BIN files. The goal is to make a large firmware library usable in everyday work: finding the right ECU or software version, examining available solutions, comparing files, and keeping related information together.
Depending on the vehicle and ECU, the collection includes original firmware, tuning files, option files, WinOLS projects, DAMOS / A2L data, gearbox files, and supporting technical material. The database already contains more than 1 million files across multiple vehicle segments.
You can explore the platform before paying. Public Firmware is available for free after registration, and registered users can search and inspect the Trust Firmware catalog before deciding whether Premium is useful for their work.
Registration and first steps
Registration and login use Google OAuth 2.0. There is no separate email/password signup form. Google sign-in helps reduce fake accounts and automated registrations.
- Open bnu.to and sign in with Google.
- Go to Shared with me to see the main shared folders.
- Open Public Firmware to browse and download free material.
- Open Trust Firmware to browse, search, and inspect the Premium collection.
- If the database fits your needs, contact me on the forum to activate Premium.
The main shared folders appear under Shared with me. Public Firmware has free downloads; Trust Firmware can be explored before purchasing Premium.
What is inside the database?
Vehicle and equipment coverage

Public Firmware vs Trust Firmware
Public Firmware — FREE
- Available after Google registration
- Open browsing and downloads
- Material collected from publicly accessible internet sources
- Includes original files, DAMOS material, and tuning-related resources, depending on the folders
Trust Firmware — PREMIUM downloads
- Searchable and viewable by registered users before purchase
- Download access enabled for Premium members
- Collections acquired for the Cloud, with duplicate cleanup performed
- Checksums calculated for approximately 96% of MOD files
- Extended firmware cards already available for approximately 50% of files
- Per-file review system
- AI-assisted search and advanced filters
- ORI vs MOD BIN comparison
- New uploads and database additions over time
Please note: A calculated checksum is not the same as a guarantee that a file has been tested or verified on a vehicle. File names, labels, and metadata should always be checked against the actual ECU HW / SW information before use.
Search files by ECU, HW, SW, model, and modification
The search is designed to save time when working with large firmware collections. You can use model names, ECU family names, software details, file types, and modification terms to narrow the results.
- Search by vehicle/model and ECU-related keywords
- ORI / MOD / BIN and stage-related filters
- Verified-only and review-status filters where metadata is available
- Optional AI search boost
- File cards with additional information where available
Search by model, ECU, file type, stage and other criteria, with optional AI assistance.
ORI vs MOD BIN comparison
The Cloud also includes tools for comparing original and modified binaries. This is useful when you have an ORI file and want to inspect what changed in a corresponding MOD file.
- Compare two BIN files
- Inspect changed bytes and ranges
- Navigate to modified areas
- Use comparison results as part of a wider verification workflow
Compare ORI and MOD binaries and inspect the changed regions instead of relying on the filename alone.
WinOLS Lab
WinOLS Lab connects Windows-based tooling to the Cloud through a worker and Lua plugin. The current build lists 84 modules covering multiple workflow families.
- Free accounts: 1 request per function per day
- Premium accounts: no free-tier per-function request limit
- Worker-based execution with a single-connection runtime
- Search, compare, checksum, export, project and helper workflows
- Checksums
- Export / Convert
- Analysis / Patch
- Project / Metadata
- OEM / Tester connectors
- Automation / Data helpers
- Bosch family modules
- Siemens family modules
- Mixed ECU families
- Specialty platforms
WinOLS Lab availability depends on the worker and the specific module. It is a supporting tool, not a substitute for checking calibration data and file compatibility yourself.
Premium access — €1,000 one time
€1,000
One payment. Lifetime Premium. No subscription.
Premium includes:
- Lifetime access to the Premium tier for as long as the service operates
- 30 Trust Firmware downloads per 24 hours
- Access to the Trust Firmware download collection
- Search and inspection of firmware metadata and available file information
- AI-assisted search and ORI / MOD comparison tools
- Premium access to WinOLS Lab functions without the free-account daily per-function quota, subject to service availability
- Future additions to the available database without a renewal payment
No monthly fee. No annual renewal. No second payment for future database updates.
The 30-download limit helps reduce automated bulk dumping, mirroring, and redistribution. It is intended to provide practical daily access without opening the entire collection to mass extraction.
How to pay and activate Premium
Two payment options are available:
- Cryptocurrency
- Direct transfer to a bank card (where supported by the sender's and recipient's banks)
Important: This is a manual payment and activation process, not an automated card checkout. Please send me a private message on BinUnlock before making any payment so we can confirm the method, payment details, and availability for your country.
Once the payment is confirmed, I activate Premium manually.
Why I am keeping the Cloud model
Not everyone needs every ECU or every file. I understand that. But maintaining a huge database as separate paid topics would also mean millions of potential listings, constantly changing files, and a lot of duplicated work.
The Cloud keeps everything in one searchable place. You can inspect the catalog, use the tools, return when you need another ECU, and benefit from new uploads over time.
I lowered the one-time price to €1,000 to make the complete platform more accessible while keeping enough resources available for storage, maintenance, and further database acquisitions.
Need an original ECU file?
If you find an original file in Trust Firmware but cannot download it with your current account, reply in this thread with the complete filename.
When I have time and the file can be shared, I may provide that original manually at no charge. This is a voluntary offer, not an automated download service.
Questions, bug reports, and requests
You are welcome to post:
- Original file requests (include the complete filename)
- Cloud login, browsing, or download problems
- Search and filtering issues
- Incorrect or incomplete ECU metadata
- WinOLS Lab issues and workflow suggestions
- Ideas for improving the platform
I am continuing to improve the system and would rather hear about problems directly than leave them hidden.
Frequently asked questions
Can I test the Cloud before paying?
Yes. Register with Google, download from Public Firmware, search Trust Firmware, and inspect the available catalog. Trust Firmware downloads require Premium.
Is Premium a subscription?
No. It is a one-time €1,000 payment with no recurring renewal fee.
How many Trust Firmware files can I download?
30 files per 24 hours with Premium.
Can I pay without cryptocurrency?
Yes, direct bank-card transfers are also possible where supported. Contact me by private message to confirm the available option.
Is the Cloud closing or moving entirely to separate Tuning Files listings?
No. I reconsidered that plan. The Cloud remains the main project and continues to receive new material.
Are all files guaranteed to work on my ECU?
No. This is a professional technical library, not a guarantee that any file is suitable for every ECU. Always verify the HW / SW match, file integrity, checksums, calibration changes, and local legal requirements before using a file.
Important usage note
Some files and modification types may be restricted for road use in certain countries. Users are responsible for complying with applicable laws and for independently validating files before flashing or using them on equipment. Database inclusion does not constitute compatibility or safety certification.
How to buy Premium
Send me a private message here on BinUnlock. I will confirm the payment option and activate Premium after payment is received.
