AEM Infinity Stand-Alone Engine Management System

$2,556.02 $3,550.03



So what if you race at the strip surrounded by corn? Who cares if the track’s seating is worse than a smaller school’s football stadium? There’s no reason you can’t use the same gear that the pros in the higher levels of motorsports use. The AEM Infinity Series of engine management systems offers unparalleled control at an affordable price.

The AEM Infinity Standalone Engine Management System packs supercharged computing power into a sealed unit suitable for engine bay mounting. With its 200 MHz, 32-bit processor with a special math co-processor, it can process 400 million instructions per second, giving you control of up to 12 peak and hold injector drivers and up to 12 ignition outputs.

The AEM Infinity also manages three analog temp inputs, 11 analog voltage inputs and seven digital inputs — the list of everything this engine management system tracks is impressive. You’ll have easy access to all that information through its IP67-rated connection system and high-speed USB data logging.

This unit gives you everything you need to tune your vehicle the best you can so you can dominate at any track, no matter how many lights and bleachers surround it.
