AEM's Infinity Series 3 Programmable ECU platform is designed for popular early- and late-model throttle body and port injected Ford, GM and Mopar V8s. The Series 3 ECUs are simplified engine controllers designed to run a basic 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.
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 drivers 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.
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 is available in our Plug & Play Adapter Harnesses section.
The Infinity's 200MHz processor and RTOS makes the Infinity more responsive, for a better driving experience
The Infinity's 200MHz processor and RTOS allows for more accurate ignition timing, which enables an engine to create more power
The Infinity's faster processor allows it to perform more computational features with no sacrifice in processing performance
The Infinity's RTOS ensures strategic processing with optimized load balancing. This means that tuning one feature will not affect the performance of another feature
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, wheel speed-based 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 operating conditions including Run Time, Peak RPM (overrev), Oil Pressure/Temp Overheat (requires sensors, sold separately) and Lean Condition (Boost/Vacuum vs AFR). All of the parameters of the Engine History feature are user programmable.
Both systems feature a small, thin footprint (7.35" x 6.55" x 1.8"), lightweight (29.9oz/848g) and 73-pin connectors. 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.

AEM is an aftermarket company and was founded by John Concialdi and Bob Sullivan back in 1987. The company specializes in providing performance upgrade parts for various automobiles.
It initially catered to vintage vehicles and modified imports used for street racing. By the early 1990s, it has already established itself as a top modifier and has been chosen by racers day in and day out.
Today, AEM has remained at the forefront in the industry and has since provided the best air intake products in the market.
The company rose to success because the cars fitted with their products won actual races. AEM has been a brand synonymous with fast cars and has been used by import racing legends such as Abel Ibarra, Adam Saruwatari, Tony Fuchs, and more.
The Tradition of Continuous Innovation
AEM has always been a pioneer in setting trends when it comes to aftermarket performance parts. They were the first to offer a packaged air induction system. This paved the way for the 'do-it-yourself' upgrade for most import vehicles.
They also pioneered the design of intake tubes with specific tube lengths and diameter, and coined the phrase Cold Air Intake when they saw the advantage of having cooler air for the engine.
Some other innovations they did were the conical air filters with built-in air horns, dual-chambered intake kits, a unique bypass valve that prevents hydro locking, hybrid induction systems, and electronically tuned air intakes.
This shows how AEM has always pushed the boundaries of air intake design in search of more horsepower.
Tried and Tested
All of AEM's products are tested by various independent and 3rd party companies and prove that their products produce the power they claimed, which helps them cement their status as industry leaders.
