Product images may differ from actual product appearance.

For computer controlled transmissions, nothing beats the new EZ-TCU by FAST. No software, laptop or tuning experience is required. Simply install this new transmission control unit according to the enclosed instructions, and then start the system by answering the simple Setup Wizard questions on the included handheld unit. It's that easy; the EZ-TCU does all the work for you! 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. 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. Compatible with most popular GM transmissions, including the 4L60E, 4L65E, 4L70E, 4L80E and 4L85E, as well as the TCI 6x Six-Speed Transmission, 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, handheld unit and wiring harness.
