AEM – A Leader In Engine Management Systems

Tags: , , , ,

imageIn today’s modern high performance vehicles the electronic components in the vehicle are as important as the mechanical components. The electronic components tell the vehicle how to perform in any given situation. It is not uncommon to see a laptop computer duct taped to a roll bar to provide the data history of the performance of the electronics. If you are truly savvy you won’t need that laptop. What you will have is an AEM programmable Engine Management System.

Programmable engine management systems allow the car’s performance to be monitored and changed with the click of a mouse. AEM brings a truly plug and play system to the performance world. The factory ECU plugs straight into the AEM ems using the standard vehicle wiring harness. No special wiring is needed. The AEM system controls the fuel injection tuning of the engine. The operating system is Microsoft Windows based using Windows 95 through ME platforms.

The AEM EMS not only provides data storage but also is a truly versatile tool for engine systems control. Multiple fuel injection drivers combined with 16 general purpose outputs and 7 definable switch inputs allow almost any component in the system to be controlled. The GPO’s are available as both high side (switched +12VDC) and low side (switched -12VDC). In addition any dedicated GPO that is not used in the system can be defined for another purpose. There are potentially over 40 GPO’s that are available in the standard system. Outputs are one thing, but inputs are another. AEM provides you with 7 switch inputs. That versatility provides even the most finicky tuner more than enough systems to work with in defining the engine management that they choose to set up.

If you have a boost controller piggybacked to your system you can pull it off and throw it away. The AEM ems includes one in the basic package. What kind of rev limiter do you want to use? This engine management system provides 5 specific definable limiters for you to pick and choose from. AEM provides a 2-step launch control that allows you a simple easy to use tool, which give you the ability to adjust to track conditions as they change during a series of races. Got gas? Nitrous that is, this ems can control wet or dry systems. One of the tools in tuning is the EGT. This engine management system allows you to utilize 4 RTD EGT sensors to be inputs. You will never have to guess again.

The electronics that control the fuel are only part of the equation to better performance. The fuel needs air to burn and there is no better way to provide a air to the engine than through an AEM cold air induction system. The AEM cold air intake and short ram air induction systems were originally provided for sport compact cars. AEM through their engineering processes knew that cold air provided better combustion than hot air does. AEM engineers placed the air filter outside the engine compartment to provide the intake with cooler air. Each air intake system is designed for a particular vehicle. There is no “one size fits all”.

When a stereo gets cranked up, you can feel the air move from the big bass speakers. AEM engineers recognize this and created the V2 Cold Air Intake. This air intake utilizes two chambers. Each of these chambers has a different length and diameter to create sound waves in different frequencies. These sound waves move the air through a corkscrew pattern in the induction system and provide a better airflow across the board no matter what the engine speed.

The AEM intake systems provided such a performance boost for sport compacts that owners of larger vehicles like SUVs and trucks demanded one. In response to these owners, AEM created the Brute Force intake. These intakes are created for each vehicle and are guaranteed for the life of the vehicle. The Brute Force induction systems are pending CARB exemption in all 50 states.

AEM provides plug and play EMS for the tuner and cold air induction systems to allow that tuner to know that the fuel provided will be burned by air supplied in the most effective manner. An easy to use engine management system tat is versatile and flexible allows setup changes for almost any environment or racing condition. AEM is the leader in EMS.
