GM E90/T93 Upgrade Kit

Upgrade your E90 ECM without pulling it from the truck. This kit lets you upgrade the E90 engine computer in 2019-2022 GM trucks for tuning, right in your own garage or shop, in as little as 20 minutes.

Why use the kit

• The ECM stays in the truck, so there's no risk of damaging delicate parts taking it out or putting it back.
• No immobilizer relearn, no crank relearn and no "Replace ECM" procedure.
• Once upgraded, you get full tuning access in VCM Suite, with write times of about 6 minutes.

Will it work on my truck?

• E90 ECM: 2019-2022 Chevrolet Silverado 1500 and GMC Sierra 1500 with the 5.3L or 6.2L V8 (L84/L87), pre-refresh, non-Global B trucks.
• T93 TCM: the kit also includes the cable for the non-Global B T93 found in the 2020 and newer Camaro, 2019-2022 Silverado and Sierra 1500, and 2020-2023 Silverado and Sierra 2500HD/3500HD (L5P). The T93 can now also be upgraded through the OBDII port at no charge, so you don't need the kit for the transmission alone.
