This service is for use with BMW ECU’s that require an OBD unlock. This applies to Gen 1 B58, B58TU, Supras, as well as few early production year S58 cars.

This unlock is ONLY for ECU’s with a manufacture date pre 06/20 (June 2020). This is to allow OBD reading/writing of the ECU and is a one-time service. If you accidentally lock your ECU after the unlock is performed, you will have to purchase it again.

Please review the options below carefully, including whether this will be used for EcuTek (the additional $520 charge is for the license fees since the EcuTek unlock requires a license – no we cannot use your license provided on a key), and whether you will be dropping the ECU off locally/arranging your own shipping, or require shipping (FedEx 2-day service).
