We listened to our customer's feedback and refined the display modes to meet the demand.

Different people, different engines, different requirements...

The lower end of the display helps with controlling staging RPM and picking smooth/consistant down change points (avoiding compression lockup and hitting the limiter).  The mid range is very useful as a performance reference and knowing how much more you have to push before the next gear change.  It's a very useful when used as a reference for improvement.  The upper range is ideal for smooth and consistent gear changes.  As the RPM climbs, you inherently predict and prepare for the gear change.  In contrast, a traditional shift light takes away some of your concentration (i.e. where is it going to flash), and it can cause more of a panic shift reaction than a planned event.

The most popular modes are the ones shown in the animation.  The high contrast mode is a favorite for drag, whereby the lower lights helps focus on the staging RPM, while the upper range provides a clear transition for accurate and consistent gear changes.  The model with the blue/red display is often the choice for this application, as the contrast is the greatest.
