Although COMPUSHIFT is fully functional without it, the optional Display / Programmer adds many new features to the system.

The display can monitor the health of your transmission by indicating the transmission temperature, current gear, torque converter lock up, and throttle position as you drive.

The display can function as a digital or bar graph tachometer or speedometer and is also a split second stopwatch.

As a special benefit and tune up aid, the display can act as a rolling dynamometer, telling you how much horsepower is being used to accelerate your vehicle.

The display can be a "G" meter, indicating the G's of acceleration or deceleration. This powerful feature allows testing of brake and engine performance. The display is also capable of indicating fault codes, should the transmission or controller experience any number system faults.

The COMPUSHIFT manual includes a full explanation on the use of the optional display.
