GM E90 ECM Service (Global B)

HP Tuners is thrilled to offer support for the GM Global B T93 TCM found in various GM vehicles equipped with the GM 10L80 10-speed transmission. This upgrade service is required to enable diagnostics and tuning capabilities in VCM Suite BETA.

This is a send-in service which means you must first send us your original TCM. Please read this page in its entirety before purchasing.

• Our T93 TCM service supports TCMs with Serv#: 24043414, 24043412, and 24294753. We do not currently support TCMs with Serv#: 24049788 and #24056863 currently. Please confirm support before purchasing this upgrade service.
• Your upgraded T93 TCM can only be tuned via the OBDII port with an MPVI3 interface and the latest version of VCM Suite (BETA) (MPVI2+ and older generation devices are not compatible with any GM Global B vehicle support).
• Once the upgrade is complete, users must license their TCM for (4) Universal Credits (sold separately).
• This is a one-time upgrade that will not affect other operations of the TCM. The factory tools will still work for service and HP Tuners will then work for tuning.
• Upon reinstallation of your upgraded control module, we recommend that you first connect to the lastest version of VCM Scanner and read/clear DTCs.
• No other tuning or calibration tools can be used with the TCM.
• VCM Scanner, dealer diagnostic, and other diagnostic tools will continue to function normally.
• The latest version of VCM Suite can be used to return to stock calibration and/or update to the latest stock calibration.
• Please also allow 1-3 business days for this upgrade service, not including shipping times.
