How it works Step 1 – File Upload (WhatsApp Live Chat) Send us your original ECU file via WhatsApp. You can upload your file as .bin / .ori / .read (depending on your tool). If you are not sure which file to send, message us and we will guide you.

Step 2 – File Processing Our technical team receives your file and professionally modifies it based on your request (Stage 1 / Economy / DPF / EGR / DTCS and more). We check the file, apply the correct calibration changes, and prepare it for safe use.

Step 3 – File Delivery We send your modified ECU file back to you via WhatsApp, ready to be written to the vehicle. You will receive a file such as tune_file_modified.bin and a short note with basic instructions.

⸻ What you need to send us • Vehicle make / model / year • Engine type & power (if known) • ECU type (if known) • Your request (Stage 1 / Economy / Custom) • Your original ECU file attachment ⸻

Important notes • Please make sure the original file is read correctly before sending. • Always write the modified file using a stable power supply/battery support.
