With track mapping configured, the race vehicle can be driven on track to collect GPS data. At the exact moment
when crossing the start/finish line, the lap beacon button should be pressed and held momentarily until both the
amber and red LEDs flash on the dash. The lap beacon button is an external input that must be added using the
violet wire input. See Figure 4. The flashing LEDs indicate that the start/finish line GPS coordinates have been
successfully set. Each time the vehicle crosses the start/finish line, a new lap will be counted and lap timer will
reset – see below for definitions of lap timing channels from AEM 5 Gauge layout.
