This one-time service upgrades your original T93 TCM that’s returning to the same vehicle it came from. Our expert team will perform the TCM upgrade without pre-programming it with a VIN. Users must physically remove the T93 TCM from their vehicle and ship it to HP Tuners’ headquarters for servicing. Once upgraded, users have full access to calibrate, log, and scan via the OBDII port.

Everything you need to tune your T93 TCM vehicle with HP Tuners:

  • This one-time, send-in GM T93 TCM Service (Global B) (upgrade service).
  • Download the latest version of VCM Suite BETA for free here.
  • Once upgraded, purchase (4) Universal Credits to license your T93 TCM.
  • GM Global B vehicle support is only compatible with our MPVI3 interface.

Note: Universal Credits for licensing are not included in the cost of any upgrade service or purchase. Credits must be purchased separately.


  • 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 to 3 business days for this upgrade service, not including shipping times.
