GM E01 ECM Service (Global B) - Upgrade Only

Tune the 2.7L Turbo. GM's Global B E01 engine computer has to be upgraded before it can be tuned. This one-time HP Tuners send-in service upgrades your original ECM so you can read, edit, flash and data log through the OBDII port with VCM Suite.

This is a send-in service. Your ECM has to come out of the vehicle and ship to HP Tuners, so the vehicle will be down while it's away. Please read this whole page before ordering.

Wait for our email before you ship. Please don't send your ECM until you have the order number and shipping form.

Before you ship: important

• Send the original ECM from your vehicle. Spare ECMs are not accepted for this service.
• Do not install and relearn a spare ECM while yours is away. If you do, your upgraded original will no longer work in the vehicle.
• After reinstalling, connect with VCM Scanner and read and clear codes first. Skipping this can cause a check-engine light or service warnings.
• Once upgraded, other aftermarket tuning tools can't be used on the ECM. Dealer tools and scan tools keep working, and you can return to stock any time with VCM Suite.
