IMPORTANT NOTES:
-
A bench read is required to determine the compatibility of your ECU(s). There
may be cases where your vehicle is listed, but your ECU may have incompatible
software versions or other minor incompatibilities.
-
Our ECU unlock service is per ECU. Some vehicle models may have
more than one ECU, so you must purchase an unlock service for each ECU
in your vehicle.
The wait is over - Unlock Your ECU
Unlock the full potential of your machine with our long-awaited ECU Unlock Service,
designed for both newer vehicles and older vehicles that have been locked out by updated
software from dealer service.
Tune over OBD or via bench flash
Modern ECUs are heavily locked down, especially after dealer flashes. Our unlock service
removes those restrictions, restoring full access so your ECU can be bench-flashed or
flashed over OBD in most cases. Whether your ECU came locked from the factory or the dealer updated
it during service, we can unlock it.
How it works
- Purchase our ECU unlock service for each of your vehicle's ECUs.
- Remove ECU(s) from your vehicle
- Carefully ship your ECU(s) to the address provided to you after purchase.
- We receive your ECU(s), unlock them, and ship them back to you.
- You receive your ECU(s) and reinstall them on your vehicle
Dealer-Update-Resistant
What happens if my vehicle is updated by the manufacturer after I unlock my ECU?
Do I have to mail my ECU again to get it unlocked?
No! You don't have to mail it again. As long as the update does not overwrite the bootloader,
your unlock remains active and can be serviced at any Cypher Pro Dealer if needed.*
We always recommend explicitly telling dealers to omit software updates on tuned vehicles
when you take it in for servicing.
**Cypher Pro Dealers may charge a labor fee at their discretion.
Tool-Friendly, Not Tool-Tied
This unlock does not marry or permanently tie the ECU to any specific device, giving you flexibility.
However, it is currently confirmed to work only with our tuning solutions and flashing tools for full
compatibility and reliability. We don't recommend you use this unlock with any non-Weistec tuning solutions.
Key Features
- Works on new and updated ECUs, including those locked by dealer software update
