HPT GM E90 ECM & T93 TCM Upgrade Kit

Unlock Your GM Truck’s Custom-Tuning Potential, Right in Your Garage

Ready to take control of how your truck performs? The HP Tuners GM E90 ECM & T93 TCM Upgrade Kit gives compatible GM owners a way to prepare their factory controller for custom tuning without removing it from the vehicle or shipping it away. Keep your original ECM in place and take the next step toward a calibration tailored to your build.

Designed for use with HP Tuners’ VCM Suite, this hardware kit enables the controller upgrade needed before you can write custom calibrations to a supported E90 ECM. It is an upgrade tool, not a replacement computer or a handheld tuner loaded with performance tunes.

Why Choose This Kit?

• Upgrade in your own garage or shop: No ECM removal or send-in service required for supported applications.
• Retain your factory controller: No immobilizer relearn, crank relearn, or replacement-ECM procedure is required.
• Prepare for custom tuning: Once upgraded and licensed, use compatible HP Tuners hardware and software to scan, log, and calibrate your vehicle.
• Purpose-built connections: Includes the upgrade box, upgrade cable, and HPTNet connections for the GM E90 ECM and T93 TCM.

E90 ECM Vehicle Compatibility

2019–2022 Chevrolet Silverado 1500 and GMC Sierra 1500 with the 5.3L L84 or 6.2L L87 V8, pre-facelift, non-Global B models only. Confirm your vehicle’s controller and electrical architecture before ordering. This kit is not the Global B ECM upgrade service.

Important T93 TCM Update

As of March 17, 2026, HP Tuners no longer requires this kit or a send-in upgrade service for supported non-Global B T93 transmission controllers. These controllers can be licensed and tuned directly through the OBDII port using compatible hardware and current software. If you only need T93 transmission tuning, check the current HP Tuners requirements before purchasing this kit.

What You’ll Need

• HP Tuners MPVI3 or MPVI4 interface and its supplied USB cable, sold separately.
• The latest version of VCM Suite BETA.
• Universal Credits to license your controller before writing a tune, sold separately and not included in this kit.
• A compatible vehicle and a suitable custom calibration; this kit does not include a performance tune.

Not compatible with MPVI, MPVI2, or MPVI2+ interfaces. Power gains and driving characteristics depend on the vehicle, modifications, and calibration, not the upgrade kit alone.
