FAQ – ECU File Upload Service
Do you use automated file generators?
No. All changes are made manually in WinOLS, followed by multiple checks. This ensures full control over every parameter and delivers safer, more reliable results.
What files do you accept?
BIN/ORI and bench/boot reads. If you’re unsure, just upload what you have. Our ECU file upload process is simple and secure.
How long does it take?
It depends on ECU and targets. We confirm the ETA after the initial review and testing process to ensure a verified result.
Is this road-legal?
Our work is intended for off-road/industrial use. Legal compliance is the customer’s responsibility.
Can you modify torque limits and DPF/EGR settings?
Yes, within safe limits and for off-road/industrial use only. We can adjust torque limiters, DPF, and EGR maps manually in WinOLS to match your requirements, while ensuring reliability and compliance with customer specifications.
Do you provide checksum correction?
Yes, checksum is verified before file delivery. This guarantees compatibility and safe flashing of the ECU file, preventing potential write errors.
Can I request multiple modifications in one file?
Yes, you can request multiple features such as power increase, torque optimization, speed limiter adjustments, and emissions-related changes (for off-road only) in a single custom ECU tuning file. We ensure all changes are harmonized for optimal performance.
At HEXTUNE LLC, every project is handled with the same attention and precision as if it were our own vehicle. We do not operate on mass production or automated systems. All ECU files are edited manually, tested, and delivered only when we are fully satisfied with the result. Our work is based on trust and long-term cooperation. We are selective with the customers we work with, ensuring mutual respect and understanding. Each day, we take on only a limited number of files so we can dedicate the necessary time and focus to every detail. This way, you can be confident that what you receive is not just a file, but a carefully prepared, factory-quality solution tailored for your needs.
