It’s that easy; the EZ-TCU does all the work for you!

Optionally Programmable Based on Load, Speed & RPM • Stores (2) Custom Calibrations • Optional Paddle Shifter

The EZ-TCU is fully configured and ready to run right out of the box – no tuning necessary. But for those who demand customization, the unit is also optionally fully programmable based on load, speed and rpm. TCI and FAST engineers took a page from the very successful FAST EZ-EFI Self Tuning Fuel Injection System and designed the EZ-TCU programming interface to be completely intuitive. There is no real expertise needed if you want to custom program your calibration. The EZ-TCU is capable of real-time switchable calibrations, which allows for multiple setups. Run one calibration on the way to the track, and then with the push of a button, have a more aggressive setup ready for the race. The multiple shift modes include full manual mode for using bump or paddle shifters.
