Each ECU is different, so always refer to our guide for supported methods.
For unlocks that support Bench, the AutoTuner Tool is guaranteed to be compatible.
For unlocks that support OBD, the AutoTuner Tool is guaranteed to be compatible. We can't guarantee all tools will be compatible, but we don't lock anyone out.
We're doing the unlock in house at our headquarters in the USA. Typically they are shipped back the same day we receive them. We process ECUs during normal business hours: M-F, 8-5 Central. We ship UPS Next Day Air in the USA, or UPS World Wide Express internationally.
Nope!
We need to protect the unlock method. Once it's known the unlock can get patched by the manufacturer and then everyone's locked out again. Secondarily, since this unlock method isn't really known, we have to take steps to protect the work.
A fully efficient system they have built.
Great service extremely quick and precise !!!!
While I haven't used their solution, I am writing this 5/5 star review for their Exceptional Technical Knowledge & Total Integrity!
I called AutoTuner USA regarding a bench unlock for my 2024 Porsche Cayenne ECU. I spoke with John, and I couldn't be more impressed with his honesty and deep industry expertise.
As a former APR employee, John has a thorough, firsthand understanding of APR's product matrix, hardware tools, and software protocols. Rather than just taking my order and having me ship the ECU to Auburn, he took the time to evaluate my exact setup (9Y0906019G S0005). He candidly explained that because my vehicle’s OBD gateway remains locked post-ECU-unlock, and because APR doesn't currently offer a bench-write solution for my specific software revision—either via APR Ultralink or through the APR Dealer network—unlocking the ECU right now would be completely ineffective for my tuning goals.
In an industry where many shops will happily charge you for a bench service you can’t immediately use, John put customer experience and technical truth first. He saved me hundreds of dollars in shipping, bench fees, and unnecessary vehicle downtime.
If you need ECU unlocking or bench work, deal with John or anyone at AutoTuner USA with 100% confidence. Top-tier professionalism!
