: If the 2D or 3D maps are laggy, ensure 3D Graphics Acceleration is enabled in the VM Display settings. 6. Best Practices for Tuning VMs

Change this to Host-only or Bridged , or disconnect it entirely if you wish to keep your tuning environment strictly offline to avoid background updates. Step 3: Install Windows and VMware Tools

Document version 1.0 – tested with VMware Workstation 17 Pro, WinOLS 47 (build 115), Windows 10 LTSC guest.

To use WinOLS for reading or writing ECUs via an interface tool, the virtual machine must communicate directly with your physical USB ports.

WinOLS 4.7 performs optimally on specific configurations of Windows 10 or 11 Pro 64-bit. A VM allows you to feed the software its exact preferred environment regardless of your host machine's hardware. Technical Prerequisites

ECU tuning software frequently requires turning off anti-virus packages or Windows Defender to prevent false-positive file deletions. Isolating the software within a VM ensures your host machine remains secure.

Go to VM > Settings > USB Controller . Ensure the compatibility drop-down matches the physical port type you are using (switch between USB 2.0 and USB 3.1 depending on your hardware interface age). Best Practices for Maintaining Your Tuning VM
