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 a full manual mode for using bump or paddle shifters.
The EZ-TCU allows for maximum electronic control over shift points, shift firmness, and shift speed. Self-diagnostics allow users of every skill level to fully utilize the EZ-TCU. The complete kit includes the transmission control unit, hand-held unit, and wiring harness.
