Car Tuning Software Frequently Asked Questions
Do you offer free ECU remapping software downloads?
Our focus is on providing professional, stable and fully supported software for ECU remapping. While you may find an ecu remapping software free download online, these tools lack the critical safety features (like checksum correction) and technical support necessary for a professional business, posing a significant risk to your customers’ vehicles.
What software do professional car tuners use?
The most widely used engine remapping software packages in the professional industry are EVC WinOLS for custom file writing and Alientech ECM Titanium for its ease of use and reliability. VIEZU is an approved supplier for both.
Is using remap software illegal in the UK?
No, the act of remapping an ECU is not illegal. However, you must ensure that any modifications are declared to your insurer and that the vehicle remains compliant with MOT emissions standards.
What’s the difference between a master and a slave tool?
A master tool reads and writes open (unencrypted) files. A slave tool is tied to a master and can only flash encrypted files supplied by that master.VIEZU supports both master tuners and a large network of slave tool users who rely on our professional tuning files.
