Why Would I Need My ECU Bench Unlocked?
Short answer: a bench unlock may be required to tune your vehicle if you have a late-model ECU or have received a software update from BMW/Toyota due to warranty, service, or recall work.
The software on these newer ECUs gets updated when the vehicle is taken to BMW/Toyota for service, warranty, or recall work. If the vehicle is updated to the latest software, it will generally lock the user out of tuning via the OBD communications port. You can confirm this by using Bootmod3, MHD, or MG Flasher and checking support for your specific vehicle. If your vehicle requires a bench unlock, you'll need this service to tune (or retune) your vehicle.
Some vehicles with the Bosch MG1 or MD1 ECU have begun getting OTA (over-the-air) software updates from BMW/Toyota. These OTA updates bring the software to the latest version but unfortunately lock many users out of tuning their vehicles. We can unlock these vehicles for you so you can tune your vehicle without issues.
How the Process Works
Option 1 — Local to Southern California
Availability: Monday through Saturday during business hours
Call Speed Logic at (888) 564-4215 to get scheduled. If you're local to our shop in Southern California, you can visit Speed Logic to get your ECU unlocked the same day with a quick turnaround. Once you arrive for your scheduled appointment, we'll remove the ECU/DME from your vehicle to begin the bench unlock process. Once complete, you'll have Read/Write access through the OBD diagnostic port without any issues, enabling you to use any tune of your choice.
Option 2 — Mail Your ECU to Speed Logic
Same-day turnaround once received
If you're not local to our shop in Southern California, we can still help. This requires removing your ECU yourself and shipping it to our shop. The process works exactly the same once we have your ECU in hand — we set it up on our bench flash setup to gain access. Once complete, you'll have Read/Write access through the OBD diagnostic port without any issues, enabling you to use any tune of your choice.
Terms & Conditions
Speed Logic is not liable or responsible for ECUs/DMEs received dead on arrival (DOA) or damaged during shipping. Please use proper packaging and insurance on any shipments of ECUs/DMEs sent to Speed Logic to ensure a smooth bench unlock process. The customer is responsible for shipping to Speed Logic, while the service cost includes and covers return shipping and insurance.
If the dealer completes a software update on your vehicle in person or through over-the-air (OTA) updates and re-locks the ECU/DME, you may need the DME unlocked again — this is an additional charge for a second bench unlock. This service includes one (1) ECU bench unlock. Mail-in pricing does not include labor to remove or reinstall the ECU/DME.
