The Details
This one-time 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 and ship it to HP Tuners’ headquarters for servicing. Once upgraded, users have full access to calibrate, log, and scan via the OBDII port.
Note: No need for an IMMO Relearn, Crank Relearn, or to perform the “Replace ECM” Function in VCM Scanner on the stock ECM.
Everything you need to tune your E99 ECM vehicle with HP Tuners:
- This one-time, send-in GM E99 ECM Service (Global B) (upgrade service).
- Download the latest version of VCM Suite BETA for free here.
- Once upgraded, purchase (8) Universal Credits to license your E99 ECM/vehicle.
- 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.
Service Notes:
- 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).

- 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.
