AEM Infinity-6 Stand-Alone Programmable EMS

$1,506.92 $2,092.95



The Infinity 506 and Infinity 508 ECUs are affordable state-of-the-art engine control units designed for four- and six-cylinder racing engines (typically Infinity 506), and racing engines with up to 8 cylinders that are using high-impedance injectors (Infinity 508). A Powersports version is available for Polaris RZR 900, 1000 and XP Turbo applications (PN 30-7112). The Series 5 features a smaller footprint than the Infinity Series 7 at 5.855” x 5.55” x 1.8”, and has a single, weatherproof 80-pin connector.

Infinity ECU modules are designed for maximum flexibility across many types of applications. ECU modules and harnesses are sold separately for both Supported and Plug & Play applications. Choose the ideal Infinity ECU based on your application’s ignition and fuel injector output requirements using the Infinity Specifications Chart, and then choose between our available Plug & Play or Universal harnesses to create the Infinity solution that suits your specific needs.

Airflow model-based (VE) tuning eliminates lookup of many correction tables needed in previous generation ECUs. Flex-fuel and multi-fuel capability, on-board wideband air/fuel control, map switching and knock control are included. Engine protection strategies include coolant temp, oil temp, AFR vs. MAP, intake air temp, knock and fuel pressure. Programmable drive-by-wire, variable cam timing, boost control, nitrous control and traction control are included.

Data logging up to 64 GB via a removable USB drive is standard with logging rates up to 1 KHz per channel. The Infinity Series 5 is able to communicate with 3rd party dashes and loggers and is AEMnet enabled. All maps can be password protected. Its sealed enclosure and IP67-rated communications ports are suitable for engine bay mounting.
