Road to Speed Week 2014 Part 1: The AEM Infinity 8 EMS and AQ-1 Data Logger

The AEM Infinity 8 EMS

The AEM Infinity 8 EMS is a 100% user programmable, total control solution.  What does this mean?  In a standard road car, you'll most likely have a combination of different control units: engine, transmission, and ABS for example to make the drive train collectively work together.  The Infinity 8 EMS simplifies this down to one system, integrating the ability to tune fuel mixture and ignition timing to develop bespoke knock, launch, boost control, and engine protection strategies. Short of getting your wife to cook and clean on command, the Infinity EMS will give you the ability to control it.

The AEM Infinity 8 EMS does so through a 32 bit 200 Mhz processor which is capable of 400 MIPS.  What exactly is 400 MIPS?  It means 400 million instructions per second, precisely half of the commands regarding lawn care that your wife can bark at you on a Sunday afternoon. In other words, it's pretty damn impressive.

 

b12 sentra ECU corroded by Bonneville SaltEven after a thorough cleaning, the ECU of my beloved B12 Sentra has still fallen victim to Bonneville's corrosive salt.  Keep in mind, this was a California car that's never seen winter and has only seen a few runs at Bonneville.

From the outside, the Infinity 8 EMS features a sealed aluminum body with water and dust proof communication ports.  In addition, the harness and connectors are fully sealed and of motorsports grade.  This is exactly what the doctor ordered since salt seems to find its way into everything at Bonneville… including the nether regions of my trousers.  In fact the packaging is so robust, the Infinity EMS is often found on boats where it's exposed to uber-corrosive environments.  

In most any other case, AEM's Infinity 6 EMS could easily handle the requirements of powering an SR20DET, KA24DE, or any other four cylinder engine.  So why'd we go with the Infinity 8?

AEM wide band turbo sensor

Put simply, we've been scheming up a twin turbo system and/or V8 swap that would allow us to attack another set of land speed records.  We're not prepared to divulge the specific combination yet.  Just understand that with its dual wide band capabilities, the Infinity 8 EMS allows us to run one wide band sensor off each turbo outlet and/or different banks of a V6 or V8.

The four individual cam phase controllers along with the eight injector and coil drivers of the AEM Infinity 8 EMS provide us with the flexibility needed to switch power trains and pursue a multitude of other land speed records.  You name the engine combination up to 8 cylinders and we can run it now.  LS7, 2JZ, VK56, or even a twin turbo four cylinder!  Point blank, we've got big plans and AEM's Infinity 8 EMS provides us with the versatility needed to make them all happen.
