No ECM Removal Needed: Tune Your E90 or T93 in Under 30 Minutes

If you’ve got a 2019-2023 Silverado or Sierra and you’ve been itching to tune it, you’ve probably run into a frustrating roadblock — the E90 ECM and T93 TCM. Up until now, tuning these modules usually meant physically removing them, sending them out, and hoping nothing got damaged along the way. That’s time-consuming, risky, and expensive.

But not anymore.

The HP Tuners ECM-00-E90-K Upgrade Kit finally delivers a seamless way to unlock tuning access without removing a single module from your GM truck. Whether you're running a 5.3L, 6.2L, 3.0L Duramax, or even the 6.6L L5P Duramax in HD trucks, this kit puts full control in your hands — and you can get it done in under 30 minutes.

What Makes the E90 and T93 So Hard to Tune?

Starting in 2019, GM rolled out the E90 ECM (engine control module) and T93 TCM (transmission control module) in many of their gas and diesel trucks. These modules are locked down tight, requiring special processes to access for tuning.

Traditionally, that meant pulling the ECM or TCM from the vehicle, shipping it to a specialist, and waiting days — sometimes weeks — to get it back. Every removal came with the risk of damaging connectors or bricking the module during reinstallation.

For DIY tuners, that was a serious barrier.

The HP Tuners E90/T93 Upgrade Kit Changes Everything

This new upgrade kit from HP Tuners makes it possible to upgrade your existing ECM and TCM in-vehicle, with no removal or special tools required. Everything is done via HPTNet cables and a simple plug-in upgrade box.

Once upgraded, you’ll gain full access to tune your ECM and TCM using the VCM Suite and your MPVI3 device — giving you the ability to optimize performance, adjust shift points, fine-tune fueling, and more.

Better yet, the process is fast. Each module can be upgraded in about 20 minutes, and write times post-upgrade are as quick as 6 minutes, making this one of the most efficient tuning solutions available for GM trucks.
