Professional ECU Service FAQ
What to know before your first ECU file job
Understand the service routes, required technical data, payment rules and protected delivery model before you search, purchase or upload.
01 What do I need for a file request?
Supply the original control-unit read, complete vehicle and ECU or TCU details, the requested solution and any relevant hardware, logs, fault codes or symptoms. Incomplete data can require additional review.
02 Can I search before uploading a file?
Yes. Use the vehicle and ECU search to find active original or ready-file listings. If no exact reference is available, start a custom request with the source file.
03 Are all catalogue files instant downloads?
Download access requires an eligible private file and verified payment. Custom services are delivered manually, not instantly.
04 What is the difference between original, ready and custom files?
Original files are unmodified references. Ready files are prepared solutions for an exact supported listing. Custom service starts with your source file and is reviewed for the specific job.
05 How do payments work?
Fast Checkout is in EUR. Account checkout offers USD only when a separate USD price and a payment provider are available. No separate account funding is required.
06 Does one purchase unlock other file types?
No. Original files, ready tuned files and custom calibration are separate products with separate prices and delivery rules.
07 Are customer and delivered files sent by email?
Files are not public downloads. Guest purchases use protected access; account purchases and custom requests use the private portal.
08 Can you guarantee an exact power increase?
No. Results depend on the vehicle, control unit, software, mechanical condition, fuel, hardware and supplied evidence. No universal output figure is promised.
09 Are emissions-related solutions road legal?
No universal legal claim is made. DPF, EGR, SCR/AdBlue, DTC and related requests are reviewed for professional, off-road, export or competition use where permitted by local laws.
10 Who can use PRO ECU FILES?
No account is needed for eligible Original and Ready Files with Fast Checkout: email, Stripe, protected download. Custom requests use an approved customer account; WhatsApp is also available for direct enquiries.
