Representing the most intensive development project in our company's history, the Quick 4 is the industry standard in electronic transmission control. With all new exclusive features, its design is not evolutionary, but revolutionary.

  • Advanced algorithms provide the highest level of shift control and synchronization, allowing you to maximize the performance of your combination.

  • The most advanced torque converter clutch control available, with several actions available during shifts.

  • Accushift ™ learning capability for the most accurate WOT shift points possible.

  • Full line pressure control for each individual shift, providing superior shift quality.

  • Adjustable throttle lift delay, overdrive shift delay, and ballistic throttle effect.

  • Burnout mode prevents upshifts while "pedaling" the throttle.

  • Up to 4 pre-loaded shift calibrations able to be selected on the fly.

  • FLEX-SHIFT ™ Shifter re-mapping capability.

  • Metric Support.

  • Transmission slip detection.

  • 100Hz high-resolution data logging of all vital parameters and viewable in a graphic interface.

  • Dedicated 4wd options and features.

  • Compact size gives you the freedom to install in tight areas (4.165 x 2.8 x 1.1 inches)

  • And many more cutting-edge features seen here.

We offer an easy upgrade program at a nominal price for existing Quick 1 customers who wish to upgrade to the revolutionary Quick 4 controller. Since all of the harnesses from our second generation controllers (Opti and Quick 1) are compatible with the Quick 4, upgrading an existing installation is a simple plug-and-play operation. In some cases, a new lead may need to be added to an existing install which would be as simple as inserting an included wire into the connector shell. Upgrading your current controller to a Quick 4 will also renew your warranty for five years.
