The Details

This one-time service upgrades an original E90 ECM (Global B generation only) and is required to enable tuning capabilities in VCM Suite. Users must physically remove their original E90 ECM from their vehicle and ship it to HP Tuners’ headquarters for servicing (shipping information below). Once upgraded and licensed, users have full access to calibrate, log, and scan directly 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 E90 ECM vehicle with HP Tuners:

  1. This one-time, send-in GM E90 ECM Service (Global B) (upgrade service).
  2. Download the latest version of VCM Suite BETA for free here.
  3. Once upgraded, purchase (8) Universal Credits to license your E90 ECM/vehicle.
  4. GM Global B vehicle support is only compatible with our MPVI3 interface.

Note: HP Tuners also supports the GM Global B T93 TCM found in some supported vehicles with the E90 ECM and 10-speed automatic transmission. See our GM T93 TCM Service (Global B) here. Email sales@hptuners.com to check if your E90 ECM vehicle also has a supported T93 TCM.

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