HPT GM E90 ECM & T93 TCM Upgrade Kit - ECM-00-E90-K - HPTECM-00-E90-K

The HP Tuners GM E90 ECM & T93 TCM Upgrade Kit (ECM-00-E90-K) is the essential solution for unlocking full tuning capability on 2019–2022 GM trucks and SUVs equipped with the E90 engine control module and T93 transmission control module. Designed to work with HP Tuners' VCM Suite, this kit lets DIY enthusiasts and professional tuners alike perform the ECM upgrade right in the garage or shop — without ever pulling the controller from the vehicle. If you've been searching for a way to get deep tune access on your late-model Silverado, Sierra, or compatible GM platform, this is the kit that makes it possible.

Key Features & Benefits

• No ECM Removal Required: The upgrade is performed in-vehicle, eliminating the risk of damaging delicate connectors or components during removal and reinstallation — a major advantage over send-in services.
• Fast Upgrade & Write Times: Each controller takes as little as 20 minutes to upgrade, and once upgraded, tune write times drop to approximately 6 minutes — among the quickest in the industry for these platforms.
• No Relearns or Reprogramming Needed: After the upgrade, there is no IMMO relearn, no crank relearn, and no need to perform a "Replace ECM" function, saving significant time and reducing complexity.
• Full VCM Suite Access: Once upgraded, the E90 ECM is fully tunable through HP Tuners' VCM Suite (BETA), giving you complete control over engine parameters on supported GM vehicles.
• DIY & Shop Friendly: Whether you're a weekend builder or a professional tuner, the kit is engineered for straightforward installation in your own garage or shop without specialized dealership equipment.
• T93 TCM Note — Important Update: As of March 17, 2026, the GM T93 TCM no longer requires an upgrade via this kit or a send-in service. The T93 can now be licensed and tuned directly via the OBDII port as normal. The GM E90 ECM, however, still requires an upgrade using this kit or the HP Tuners send-in service.

Frequently Asked Questions

Do I need to remove the ECM from my truck to use this kit?

No. One of the key advantages of the HP Tuners E90/T93 Upgrade Kit is that the entire upgrade procedure is performed with the ECM still installed in the vehicle. This eliminates the risk of connector or component damage that can come with physical removal.

Does this kit work with my older HP Tuners MPVI2 or MPVI2+ device?

No. This kit is only compatible with the MPVI3 or MPVI4 interface device. It will not function with MPVI, MPVI2, or MPVI2+ hardware. Make sure you have the correct HP Tuners interface before ordering.

Do I still need this kit to tune my T93 transmission control module?

As of March 17, 2026, the T93 TCM no longer requires an upgrade via this kit or a send-in service. You can now license and tune the T93 TCM directly through the OBDII port using VCM Suite. However, the GM E90 ECM still requires an upgrade — either through this kit or HP Tuners' send-in service — before it can be tuned.

Are HP Tuners credits or a VCM Suite license included with this kit?

No. This kit contains the hardware cables and upgrade components needed to unlock the ECM for tuning, but HP Tuners VCM Suite (BETA) and vehicle licensing credits must be purchased separately. You will need to license the vehicle through HP Tuners before writing a tune file.
