Page 2 of 12 Thank you for purchasing an AEM Engine Management System. The AEM Engine Management System (EMS) is the resul t of extensive development on a wide variety of cars. Each system is engineered for the particular application. The AEM EMS differs from all others in several ways. The EM S is a stand alone system, which completely replaces the factory ECU and features un ique Plug and Play Technology, which means that each system is configured especial ly for your make and model of car without any jumper harnesses. There is no need to m odify your factory wiring harness and in most cases your car may be returned to stock in a matter of minutes. For stock and slightly modified vehicles, the suppl ied startup calibrations are configured to work with OEM sensors, providing a solid starting p oint for beginner tuning. For more heavily modified cars, the EMS can be reconfigured to utilize aftermarket sensors and has many spare inputs and outputs allowing the eliminat ion of add on rev limiters, boost controllers, nitrous controllers, fuel computers, e tc. It also includes a configurable onboard 1MB data logger that can record any 16 EMS paramete rs at up to 250 samples per second. Every EMS comes with all functions installe d and activated; there is no need to purchase options or upgrades to unlock the full pot ential of your unit. The installation of the AEM EMS on the supported ve hicles uses the stock sensors and actuators. After installing the AEMTuner software, the startup calibration will be saved to the following folder on your PC: C:\Program Files\AEM\AEMTuner\Calibrations\Mitsubis hi-DSM\ Multiple calibrations may be supplied for each EMS; additional details of the test vehicle used to generate each calibration can be found in t he Calibration Notes section for that file. Please visit the AEM Performance Electronics Forum at http://www.aempower.com and register. We always post the most current strategy release, PC Software and startup calibrations online. On the forum, you can find and share many helpful hints/tips to make your EMS perform its best. TUNING NOTES AND WARNING: While the supplied startup calibration may be a goo d starting point and can save considerable time and money, it will not replace th e need to tune the EMS for your specific application. AEM startup calibrations are not inten ded to be driven aggressively before tuning. We strongly recommend that every EMS be tun ed by someone who is already familiar with the AEM software and has successfully tuned vehicles using an AEM EMS. Most people make mistakes as part of the learning p rocess; be warned that using your vehicle as a learning platform can damage your engi ne, your vehicle, and your EMS.
Page 3 of 12 Read and understand these instructions BEFORE attempting to install this product. 1) Install AEMTuner software onto your PC The latest version of the AEMTuner software can be downloaded from the AEMTuner section of the AEM Performance Electronics forums. Series 2 units are not supported by the older AEMPro tuning software. 2) Remove the Stock Engine Control Unit a) Access the stock Engine Control Unit (ECU). The loc ation of the ECU on the 1G DSM vehicles is behind the radio in the center cons ole. b) Carefully disconnect the wiring harness from the EC U. Avoid excessive stress or pulling on the wires, as this may damage the wiring harness. Some factory ECUs use a bolt to retain the factory connectors, and it must be removed before the harness can be disconnected. There may be more than one connector, and they must all be removed without damage to work properly with the AEM ECU. Do not cut any of the wires in the factory wiring harness to remove them. c) Remove the fasteners securing the ECU to the car bo dy, and set them aside. Do not destroy or discard the factory ECU, as it can b e reinstalled easily for street use and troubleshooting. 3) Install the AEM Engine Management System a) Plug the factory wiring harness into the AEM EMS an d position it so the wires are not pulled tight or stressed in any manner. Secure the EMS with the provided Velcro fasteners. b) Plug the comms cable into the EMS and into your PC. c) Turn the ignition on but do not attempt to start the engine. d) The USB drivers must be installed the first time yo u connect to a Series 2 EMS with an onboard USB port. When the Series 2 EMS is conne cted to the PC’s USB port and receiving power from the vehicle, the “Found Ne w Hardware” window will appear. Select “Install from a list of specific lo cation (Advanced)” and browse to the following folder: C:\Program Files\AEM\AEMTuner\USB Drivers (Series 2 )\ e) With the AEMTuner software open, select ECU>>Upload Calibration to upload the startup calibration file (.cal) that most closely m atches the vehicle’s configuration to be tuned. Check the Notes section of the calibratio n for more info about the vehicle it was configured for. These files can be found in the following folder: C:\Program Files\AEM\AEMTuner\Calibrations\Mitsubis hi-DSM\ f) Set the throttle range: Select Wizards>>Set Throttle Range and follow the on screen instructions. When finished, check that the ‘Throttle’ channel never indicates
Page 4 of 12 less than 0.2% or greater than 99.8%, this is considered a sensor error and may cause some functions including idle feedback and ac celeration fuel to operate incorrectly. 4) Ready to begin tuning the vehicle. a) Before starting the engine, verify that the fuel pu mp runs for a couple of seconds when the key is turned on and there is sufficient p ressure at the fuel rail. If a MAP sensor is installed, check that the Engine Load indicates something near atmospheric pressure (approximately 101kPa or 0 PSI at sea level) with the key on and engine off. Press the throttle and verify that the ‘Throttle’ channel responds but the Engine Load channel continues to measure atmosp heric pressure correctly. b) Start the engine and make whatever adjustments may be needed to sustain a safe and reasonably smooth idle. Verify the ignition tim ing: Select Wizards>>Ignition Timing Sync from the pull down menu. Click the ‘ Lock Ignition Timing’ checkbox and set the timing to a safe and convenient value ( for instance, 10 degrees BTDC). Use a timing light and compare the physical timing numbers to the timing value you selected. Use the Sync Adjustment Increase/Decrease buttons to make the physical reading match the timing number you select ed. c) Note: This calibration needs to be properly tuned b efore driving the vehicle. It is intended for racing vehicles and may not operate sm oothly at idle or part throttle. NEVER TUNE THE VEHICLE WHILE DRIVING 5) Troubleshooting an engine that will not start a) Double check all the basics first… engines need air , fuel, compression, and a correctly timed spark event. If any of these are la cking, we suggest checking simple things first. Depending on the symptoms, it may be best to inspect fuses, sufficient battery voltage, properly mated wiring connectors, spark using a timing light or by removing the spark plug, wiring continuity tests, m easure ECU pinout voltages, replace recently added or untested components with known good spares. Check that all EMS sensor inputs measure realistic temper ature and/or pressure values. b) If the EMS is not firing the coils or injectors at all, open the Start tab and look for the ‘Stat Sync’d’ channel to turn ON when cranking. Thi s indicates that the EMS has detected the expected cam and crank signals; if St at Sync’d does not turn on, monitor the Crank Tooth Period and T2PER channels w hich indicate the time between pulses on the Crank and T2 (Cam) signals. B oth of these channels should respond when the engine is cranking, if either sign al is not being detected or measuring an incorrect number of pulses per engine cycle the EMS will not fire the coils or injectors. c) If the Engine Load changes when the throttle is pre ssed this usually indicates that there is a problem with the MAP sensor wiring or so ftware calibration (when the EMS detects that the MAP Volts are above or below t he min/max limits it will run in a failsafe mode using the TPS to Load table to gene rate an artificial Engine Load signal using the Throttle input). This may allow th e engine to sputter or start but not continue running properly.

WARNING:
* The factory A/C request switch sends 12V power to signal an A/C request and the 30
6311 EMS has been designed to accept 12V power on t his switched input. If users desire
to re wire a new switch to trigger the Switch 2 inp ut the switch should connect to 12V
power when the switch is on. The pin can be left fl oating (disconnected) when the switch is
off, it is not required to send ground to this pin.
**All other switch input pins must connect to groun d; the switch should not provide 12V
power to the EMS because that will not be detected as on or off. Connecting 12V power to
the Switch 3, Switch 4 or Switch 5 pins may damage your EMS and void your warranty.
Wiring harness destinations for non USDM vehicles m ay be different than listed in the
pinout charts below. If installing this EMS on a ve hicle not originally sold in the US, please
verify that the vehicle’s wiring harness matches th e pinout shown here.
The function of the following pins have been change d from the original 30 1311 EMS,
please see pinout chart for more info:
80(51), 81(52), 82 (53), 85(56), 89(60), 90(61), 91 (62), 104(34), 114(44)
Primary Load Sensor, EMS Fuel Strategy
The factory MAF (mass air flow) sensor can be remov ed to help decrease intake air
restriction; the EMS can be configured to use a MAP sensor to determine engine load.
It is recommended to use a 3.5 bar MAP sensor or hi gher (P/N 30 2130 50).Please be
aware that the IAT (intake air temperature) sensor is integrated into the factory MAF
sensor. If the factory MAF / IAT sensor is removed, you may wish to install an AEM IAT
Sensor Kit (P/N 30 2010), which includes a sensor, wire connector, and aluminum weld in
bung. While the factory MAF sensor locates the IAT sensor upstream of the turbocharger
inlet, it may be preferable to install an IAT senso r downstream of the intercooler to
accurately measure charge temperatures.
The factory Mass Air Flow and Intake Air Temperatur e sensors can be used as the
primary load input for the AEM EMS if desired. Plea se check the Notes section of each
calibration for more info about the vehicle setup a nd fuel strategy that calibration was
configured to use.
EMS Fuel Map, Boost Fuel Trim Table
The 30 6311 maps provided utilize the “Boost Fuel Trim Table” to provide a 1:1 fuel
compensation above and below atmospheric pressure. In the startup calibration, the
“ Boost Fuel TrimTable ” is configured to provide twice as much fuel when the manifold
pressure is twice as high and half the fuel when th e manifold pressure is half as high; this
should help simplify the tuning process for differe nt vacuum and boost levels. Notice the
values in the main “Fuel Map” do not change above 100 kPa (0 psi boost), the fuel
correction is being made by the “Boost Fuel Trim Table.”
Note: the “Boost Fuel Trim Table” must be adjusted if a different MAP sensor is insta lled or
if the Load breakpoints are adjusted. The Boost Fue l Correct value should be set to 90 at
10kPa, 0 at 100 kPa, +100 at 200 kPa, +200 at 300 k Pa, etc…
Page 7 of 12 Peak and Hold Injector Drivers Injectors 1 6 include Peak (4 amps) and Hold (1 amp ) injector drivers. These drivers may be used with peak and hold or saturated type inject ors. The factory Mitsubishi wiring harness contains a resistor pack to prevent excessi ve current when using low impedance injectors with the stock ECU. With the 30 6311 inst alled, users can elect to remove and bypass the OEM resistor pack for more precise contr ol of low impedance injectors. Please note that the injector response time will be different with and without the factory injector resistor pack. If the OEM resistor pack ha s been removed and bypassed, please choose the correct battery offset for your injector s using the Setup Wizard. Most battery offset wizard configurations will specify if they are intended for use without a resistor pack. Unused accessories: The EMS does not support the Active Exhaust found o n the 91 93 models. If you still have this, it must be disconnected from the ECU (pin 102 ). If not disconnected, a whirring noise will be heard from the AE drive motor located in th e left rear quarter panel on the car. While this causes no damage, it is quite annoying. The stock “boost” gauge is not used. Wiring accessories to the EMS: Please follow this suggested wiring diagram when ad ding accessories such as UEGO gauges, MAP sensors, IAT sensors, or switches for u se with the EMS. Note that wire polarity is not important for the Air Temperature s ensor.
