The supported ECU list (publicly published at DaVinci_Deluxe_Supported_List.pdf) and our pricing page state this scope explicitly before purchase.

No-refund policy for HD truck mistakes: Purchasing DaVinci Deluxe to attempt work on any of the above is the customer's sole responsibility. Coverage scope is disclosed (a) on the pricing page, (b) on the checkout interstitial page, (c) on the publicly available supported list PDF, and (d) in this policy. Buying the license and afterwards discovering the truck or off-highway engine is not in the catalog does NOT constitute a valid refund ground, nor a basis for chargeback or dispute. By completing checkout you confirm you have read these disclosures and accept this exclusion.

For HD truck remapping work, professional alternatives include Magic Motorsport Flex, Dimsport New Genius, CMDFlash HD pack — none of which we resell or are affiliated with. Choose the right tool for your fleet.

🔒 2.2 HWID Freeze on Cancellation — Multi-Account Abuse is Forbidden

Each DaVinci Deluxe license is bound to one or more physical computers via a Hardware ID (HWID) generated by the desktop launcher (SHA-256 hash of CPU + motherboard + disk identifiers). This binding is permanent and serves as both license enforcement and anti-piracy protection.

At the moment your subscription is cancelled (by you, by us, or via Stripe payment failure), the following automatic actions take place:

• All HWIDs currently bound to your account are copied to our frozen_hwids registry and locked to your user_id.
• You can NO LONGER remove, reset, or transfer your HWIDs from /profile or via any API endpoint.
• Any new DaVinci Deluxe account created with the same physical computer will be blocked at login: the software will refuse to start and the new account will be flagged as multi-account abuse.

The only legitimate way to reuse a frozen HWID is to re-subscribe with your original email. Re-subscribing reactivates your previous HWID(s) automatically (subject to the Welcome-Back Loyalty Restoration Fee disclosed in section 2.1).

No-refund policy for HWID-freeze circumvention: Creating a second DaVinci account in an attempt to bypass the HWID freeze is considered multi-account abuse and fraud. If detected, we will (a) ban the new account, (b) freeze all HWIDs of the new account too, (c) report the fingerprint pattern to Cloudflare for edge-level blocking, and (d) refuse any refund request related to either the original or the new account, including chargeback disputes. Stripe / Cloudflare / Telegram alerts log the attempt with timestamp and IP, providing the evidence we use to contest any reverse-payment claim with your bank.

By purchasing, subscribing, or activating DaVinci Deluxe you confirm you have read this HWID freeze policy and agree that any attempt to circumvent it forfeits your right to refund, partial refund, or chargeback. The disclosure is logged on (a) this policy page, (b) the /profile cancellation box shown before any cancel action, (c) the Stripe checkout interstitial, and (d) the refund policy at the time of purchase.

⚠️ Installation & Requirements

🛡️ 1. Disable Antivirus & Windows Defender

DaVinci Deluxe is 100% clean and safe. However, because it modifies engine mapping files securely and uses specialized cryptography, security heuristics often flag it as a false positive. You must completely disable your antivirus before extracting the ZIP file.

💡 Pro Tip: We have included a tool named "Disable Windows Defender" in the ZIP. Open it, select Option 3, then select Option 1. This will automatically and safely disable Windows Defender and SmartScreen.

🐍 2. Install Dependencies (Python & C++)

Before opening DaVinci, you must install the required dependencies included in the ZIP file. Depending on your PC architecture (32-bit or 64-bit), you must install both:

• Python (32-bit or 64-bit) included in the folder.
• C++ Redistributable (32-bit or 64-bit) included in the folder.

🚀 3. Launch DaVinci Deluxe

Once Windows Defender is disabled and the dependencies are properly installed, you can safely open DaVinci Deluxe. Right-click and run as Administrator for the best experience.
