The software interface included with the programmable 6AL-2 is remarkably easy to use. Timing can be adjusted in 100-rpm increments by simply dragging plot points on the graph. Timing retard is on the Y-axis, while rpm is on the X-axis. All the end user has to do is place the data plots based on the amount of timing retard desired. The 6AL-2 also features boost retard functions, three different rev limiters, and a nitrous activation wire.
