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

This is the modification service ONLY. Shipping charges apply.  Licensing, tuning, and modifications are additional.

This C8 ECM Unlocking Service upgrades your original E99 ECM (Global B generation only) and is required for tuning using HP Tuners’ software. Users must physically remove their original E99 ECM from their vehicle for servicing. Once upgraded, users have full access to calibrate, log, and scan via the OBDII port.

• Your upgraded E99 ECM 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 ECM for (8) Universal Credits (sold separately).
• 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 ECM.
• 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.
• There is no need for an IMMO relearn, crank relearn, or the “Replace ECM” function as long as the ECM returns to the same vehicle it came from.
• Please allow 2 to 4 business days for this upgrade service, not including shipping times.
