FAQ
Questions about this system
How many cars can run on course at once?
AC4 systems support up to 4 cars simultaneously. For unlimited cars, use the 5840 PC-based system.
Is AXWare SCCA-sanctioned?
AXWare is built around SCCA Solo rules including run groups, PAX indexing, penalty scoring, and class structures. It's in active use at Divisional and National events.
How long does setup take?
AC4 wireless: typically 15–20 minutes. Hardwired adds cable runs (100–1000ft) depending on course length. The USB-rechargeable IR emitters run 55–60 hours on a charge.
