FAST EZ TCU Master Kit

The FAST EZ TCU Master Kit is built around a sophisticated transmission controller that gives you significant electronic command over your automatic transmission's behavior. This unit is designed to manage shift points, how firm each shift feels, and how quickly it happens. It's a well-built piece of equipment that can make a notable difference in how your vehicle performs, especially if you're looking to fine-tune your transmission's response for different driving conditions.

What's really convenient about this EZ TCU is that it's ready to go right out of the box, meaning you don't need to be a tuning expert to get it working. It walks you through a simple setup wizard using the included handheld device, asking basic questions to get your transmission shifting correctly. However, if you do want to dig deeper, the EZ TCU is also fully programmable. You can adjust calibrations based on factors like engine load, vehicle speed, and RPM, giving you the flexibility to create custom shift strategies. This allows for real-time switchable calibrations, so you could have one setup for daily driving and a more aggressive one for track use, all selectable with a button.

This controller also offers a full manual mode, which is great if you're using paddle shifters or a bump shifter. It includes power data logging and self-diagnostics, which are helpful tools for understanding your transmission's performance and troubleshooting any issues. Keep in mind that this kit is not CARB approved and cannot be shipped to California. It's a solid option for anyone wanting more precise control over their automatic transmission's shifting characteristics.
