AEM Releases Plug & Play Infinity ECU Harnesses for

USDM 2003-’05 Mitsubishi EVO VIII and 2006-’07 EVO IX!

Unit replaces the factory ECU, fits in factory ECU location, and installs in about 30 minutes

Hawthorne, CA—AEM has released its Infinity-6 (30-7106) ECUand Plug & Play Adapter HarnessesforUSDM 2003-’05Mitsubishi EVO VIII (PN 30-3511) and 2006-’07 EVO IX (PN 30-3512) racecars. When combined with AEM’s Plug & Play Adapter Harness and conversion from mass airflow to speed density, the Infinity completely replaces the factory Mitsubishi ECU on these vehicles. The use of an Infinity-8h is possible with these Plug & Play harnesses, but some of the OEM functions capable when using the Infinity-6 will be eliminated. Base maps for the engines are included, and non-USDM EVOs are supported (contact AEM to verify the correct application).

Speed Density Fueling Control

The Infinity ECU does not support the Mitsubishi factory Mass Airflow sensor (MAF) and provides for speed density fueling control, allowing users to eliminate the factory MAF. AEM offers MAP and Inlet Air Temperature (IAT) sensors for wiring into the Plug & Play Harnesses’ auxiliary port for converting from MAF to speed density (MAP/IAT).

Uses Factory Boost Control Solenoid and Clutch Switch

The Infinity EVO VIII & EVO IX Plug & Play Adapter Harnesses support the factory boost control solenoid or an aftermarket boost control solenoid if added.The factory clutch switch is supported in both vehicles for using a 2-step limiter and for launch control. The factory variable speed radiator fan control is also supported in both applications.

MIVEC Variable Cam Timing for EVO IX

The Infinity ECU and EVO IX Plug & Play Adapter Harness (PN 30-3512) allow for programmable variable cam timing of the Mitsubishi MIVEC system.

Provides for Easy Upgrade to Sequential Ignition

The Infinity ECU and Plug & Play Harnesses for the EVO VII and EVO IX lets users to easily upgrade the factory wasted spark ignition system to a sequential ignition system using high output coils (sold separately). The factory wasted spark ignition system is also supported.

Plug & Play Harness with Expansion Port

AEM’s sealed, weatherproof Plug & Play harnesses for the Mitsubishi EVO VII/IX include an AEMnet port for communication with other AEMnet enabled devices.

An expansion port with a weatherproof 12-pin connector is included in the Plug & Play Adapter Harness for adding common aftermarket sensors including fuel pressure and ethanol content. The expansion port also includes a sensor ground, 5v reference, power from relay and switched inputs for boost target, no-lift shift, etc.
Infinity-6/8h ECU Features (Mitsubishi EVO VIII/IX):

  • Airflow model based (VE) tuning
  • ECU Set Up Wizard simplifies start up
  • Flex fuel compatible
  • Programmable drive by wire
  • Multiple programmable boost control strategies
  • Programmable 2-step and 3-step launch control
  • Programmable nitrous control
  • On-the-fly map switching
  • Single internal Lambda controller
  • Dual knock sensing circuits
  • Data logging up to 64GB, logging rate up to 1KHz/channel
  • Outputs to 3rd party dashes and data loggers
  • Industry leading data transfer speed (up to 480Mb/sec)
  • Integrated engine protection strategies
  • Sealed enclosure and IP67 rated comms ports

The Infinity ECU makes state-of-the-art ECU technology affordable for both professional teams and amateur racers. Built around a latest-generation 32 bit floating point 200MHz automotive processor and Real Time Operating System (RTOS), the Infinity is capable of processing 400 MIPS (millions of instructions per second). To our knowledge, the Infinity ECU currently has the fastest processing speed of any aftermarket Motorsports ECU available. This processing speed combined with a RTOS provides more accurate ignition timing for increased power, more responsiveness to truly custom tailor the driving experience to the driver, allows the Infinity to perform more computational features without a sacrifice in processing performance, and enables tuning of features and sub strategies without affecting other features and sub strategies. It allows you to do more, faster, in a more stable programming environment.
