The AEM 30-8409 CAN Bus Data Logger is an ultra-compact, hidden solution for comprehensive vehicle data acquisition, perfect for setups that require high-speed logging without the bulk or expense of a digital dash. This rugged, IP67 waterproof device allows racers and tuners to record data from two completely separate CAN networks simultaneously at blazing-fast sample rates up to 1KHz. Measuring just 2" x 2", it tucks away neatly behind the dash and logs directly onto a standard external USB flash drive up to 32GB, making it the ultimate tool for precise, hidden diagnostics and performance tracking.
