If the date resets after a reboot, the hardware clock is failing.
WinOLS 4.7 is a highly sought-after tool for engine control unit (ECU) modification. Because unauthorized versions and third-party activations are widely circulated, developers implement strict cryptographic security measures. One common protection mechanism is a "time-bomb" or expiration check. The software continuously verifies the local computer date against a secure internal timestamp or hardcoded range embedded during compiling. If it detects that your local clock does not align with its internal protocol, it flags the installation as suspicious and locks you out. 2. Time-Sync Discrepancies and Windows Updates
Select under "Set the date and time manually" and input the earlier date.
This issue primarily impacts automotive tuners utilizing unauthorized or cracked versions of EVC WinOLS 4.7, which contain time-locked "loaders" or digital signatures that trigger an expiration warning when synced with current, real-world internet time. Why WinOLS 4.7 Triggers the System Date Error winols 47 your system date is wrong hot
Here is a final checklist to resolve the "Your system date is wrong" error for good. Follow these steps in order for the best chance of success:
Windows frequently updates its clock during silent maintenance cycles. Go to your Windows Control Panel, select Clock and Region , choose Internet Time , click Change Settings , and completely uncheck Synchronize with an Internet time server .
| Risk | Consequence | |------|-------------| | | Many "hot fixes" contain ransomware, keyloggers, or miners. | | Corrupt ECU files | A modified WinOLS may calculate checksums incorrectly → bricked ECU. | | No updates | You miss new maps, protocols, and bug fixes. | | Legal issues | EVC actively pursues piracy. | | Time bombs | Even after fixing date, a hidden trigger may corrupt your database after X days. | If the date resets after a reboot, the
Does the time every time you reboot your PC?
: If your version relies on a hardcoded manual system clock rollback, turn off internet sync under Windows Date & Time settings to prevent the OS from automatically jumping forward to the true current year.
Even if the time looks correct, an incorrect time zone can trigger security errors in EVC software. One common protection mechanism is a "time-bomb" or
I can give you more precise instructions on how to set it up.
Once the date is changed, try opening the software again. 2. Using "RunAsDate" (Recommended)
: Using WinOLS on virtual machines (VMs) can sometimes cause time-sync issues if the VM host and guest have different time settings.
Right-click it, select , and change the startup type to Automatic .
