Autotuner - DME Remote Unlock for MDG1 Series DME (7/2020+) - Toyota GR Supra

Now offering Remote Unlock provided by Autotuner in UK. All GR Supra vehicles with a production date after 07/2020 require the Autotuner unlock for flash-based tuning. Once your DME is unlocked, this enables OBD based tuning. This is required beforehand for such platforms as Bootmod3, and MHD Tuning through the OBD2 Port.

Starting July 2020 and onward, all GR Supra DMEs produced were shipped with an updated bootloader that rendered OBD Flash Tuning using existing protocols impossible. For a short time, there was no solution for this problem. Currently, as the community still anxiously waits for a US-Based DME Unlock for MDG1 DMEs, there is a solution available. The company known as Autotuner offers a mail-in service now known as the Autotuner DME Permanent Bench Unlock. This unlocks your DME, making OBD Flash Programming possible. 

Unlocking Process Outline

• Permanent DME Unlock. If overwritten from dealer by mistake, can be re-unlocked at our facility without shipping back to Autotuner UK
• For vehicles serviced in-house, this includes DME removal and reinstallation
• For Mail Order: Purchase the Unlock procedure from this page. With purchase, you’re also purchasing your Return Shipping Label
  
• Remove your DME from your vehicle
  
• Mail your DME to our facility for preparation
  
• Typical wait time is 5-7 days (sometimes sooner) in which your DME will be unlocked and returned to you
• Reinstall DME in your vehicle, remember to turn off OTA updates

In the meantime your DME will be shipped via DHL to Autotuner/UK, where it will be unlocked and returned to our facility in Anaheim, CA. In most cases with standard shipping this is about ~5-7 business day turnaround, sometimes sooner in some cases. Additionally, as an added safeguard - we add Apple AirTag tracking devices to each DME shipment prior to shipping.
