New from AEM – the Infinity Series 3 programmable ECU. This unit will run a race, marine, or crate engine and offers fuel injection control, flex fuel compatibility, and a host of other features. See more details below.

Official Release:

AEM has released the Infinity Series 3 Programmable ECU platform for popular early- and late-model throttle body and port injected Ford, GM and Mopar V8s. The new Series 3 ECUs are simplified engine controllers designed to run a race, marine or crate engine without the need for, or cost of, additional features like variable cam control, Drive-by-Wire throttle control or internal wideband air/fuel sensor controllers. Initial release of the Series 3 includes the Infinity 308 (PN 30-7113) and Infinity 358 (PN 30-7114). Both Infinity Series 3 systems are offered at a special introductory retail price of only $999.00. Once this promotional introductory price ends, The Infinity 308 will retail for $1,198.00 and the Infinity 358 will retail for $1,248.30.

INFINITY 308

The Infinity 308 (PN 30-7113) features two different injector types and two different coil outputs that support three different types of fuel and ignition configurations.

For throttle-body-injected (TBI) and GM multi-port fuel injected V8s the Infinity 308 includes a single direct-drive ignition coil output to work with a distributor and a single coil, and 2 peak & hold injector drivers that can drive up to four high-impedance injectors each. Other port injected and single-coil distributed V8 engines like the Ford Windsor can be controlled using the Infinity 308’s 8 high impedance injector divers and single direct-drive coil output.

For the Chevy LS, the Infinity 308 has 8 high impedance injector drivers and 8 “smart” coil outputs to drive a coil-near-plug ignition system.

Infinity 308 MEFI Upgrade

The Infinity 308 is a great upgrade for users looking to replace their older MEFI-4 system. This system also provides users with an upgrade path to sequential port injection and “smart” coil-near-plug ignition. A Plug & Play Adapter harness to install an Infinity 308 on engines using MEFI controllers will be available in the near future.

INFINITY 358

The Infinity 358 (PN 30-7114) is designed to control 2V and 4V Ford Modular engines, late-model Dodge Hemi engines and other late-model, individual direct-drive “dumb” coil V8 engines with port injection using 8 high impedance injectors.

INFINITY SERIES 3 FEATURES

Designed for the price conscious racer, the Infinity Series 3 incorporates all of the features necessary to run a high performance engine including airflow-based VE tuning for fuel injection control, ignition control, Flex Fuel, knock control, boost control, nitrous control, launch control, traction control and engine protection. The Series 3 is able to communicate with 3rd party dashes and loggers and is AEMnet CANbus enabled to easily communicate with other AEMnet equipped devices. All maps can be password protected. Its latest generation 200MHz processor can process 400 MIPS (Millions of Instructions Per Second).

Air/Fuel Ratio (AFR) feedback is supported by adding external wideband controllers through 0-5V analog inputs or via AEMnet CANbus using AEM’s X-Series Wideband UEGO AFR controllers. An Engine History feature is included that records basic engine operational conditions including Run Time, Peak RPM (overrev), Oil Pressure/Temp Overheat (requires sensors, sold separately) and Lean Condition (Boost/Vacuum vs AFR).

Both systems feature a 7.35” x 6.55” x 1.8” footprint, weigh 29.9oz/848g and have a 73-pin sealed connector. The Infinity Series 3 enclosure is fully sealed and the connectors are IP67 rated (dustproof, waterproof to 1 meter) making the Infinity suitable for engine bay mounting.

Marine Version Coming Soon!

AEM will be releasing a Marine specific version of the Infinity Series 3 ECU for upgrading popular marine V8 engines to standalone engine control. It will have dedicated marine-specific Firmware and software with features designed specifically for marine applications. Along with the Series 3 Marine Firmware/software, AEM is releasing a NMEA-Certified AEMnet to NMEA Gateway that will convert the AEMnet CAN bus protocol to NMEA protocol. Even more exciting is the Series 3’s ability to run Mercruiser marine engines equipped with MEFI-3 or MEFI-4 ECUs by using Infinity plug & play adapter harnesses that will deliver a seamless conversion from a MEFI to the Infinity Series 3. A complete list of features will be announced when the Infinity Series 3 marine software is released.

Wiring Harnesses

AEM offers a flying lead wiring harness for the Infinity Series 3 platform that is 96” in length and pre wired with power, grounds, a power relay and AEMnet (PN 30-3707). A Plug & Pin kit (PN 30-3708) is also available for the Series 3 that includes a 73-pin connector with cover, 73 small pins, 1 micro relay with pins and 30 sealing plugs.

Support

The Infinity Series 3’s capabilities combine with AEM’s industry leading after-purchase support system that includes free technical support to deliver the ultimate engine control solution for budget minded race teams and weekend track cars with crate V8s and engines up to 8 cylinder using throttle body injection or high impedance injectors.
