AEM EMSAEM Performance Electronics is pleased to introduce its Series 2 Plug and Play Standalone Engine Management System for a wide variety of Nissan 4 and 6cyl applications, including 240SX, Silvia, Skyline, Sentra, 300ZX, SR20 swaps, and more.  The Series 2 EMS for Nissans, which replaces AEM’s first generation EMS, represents a complete hardware redesign with greatly enhanced features, including a USB data port, 1MB of internal data logging, up to 6 peak and hold and 6 saturated injector drivers, and up to 6 coil outputs.  In addition, all Series 2 EMS systems come loaded with the company’s new AEMTUNER software, a completely new user interface software which replaces AEMPRO. AEMTUNER is only available on Series 2 systems.

“At AEM Performance Electronics we strive to continually evolve and improve our products”, stated Director of Product Development John Romero.  “The Series 2 EMS represents significant improvements over our first generation systems in the areas of both hardware and software.  If you liked the first EMS, you’ll love Series 2 and AEMTUNER”.

AEM’s new AEMTUNER software is a complete software redesign and replaces AEMPRO.  It includes many new features including a context sensitive tuning support system which significantly increases ease of tuning even for tuners who have never used AEM software.  Visit for more details and overview videos.
