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 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.
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.
