Thank you for purchasing an AEM Engine Management System.
The AEM Engine Management System (EMS) is the result 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 EMS is a stand alone system, which
completely replaces the factory ECU and features unique Plug and Play Technology,
which means that each system is configured especially for your make and model of car
without any jumper harnesses. There is no need to modify 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 supplied startup calibrations are configured to
work with OEM sensors, providing a solid starting point 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 elimination of add-on rev-limiters, boost
controllers, nitrous controllers, fuel computers, etc. It also includes a configurable onboard
1MB data logger that can record any 16 EMS parameters at up to 250 samples per
second. Every EMS comes with all functions installed and activated; there is no need to
purchase options or upgrades to unlock the full potential of your unit.
The installation of the AEM EMS on the supported vehicles 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\Mitsubishi-DSM\
Multiple calibrations may be supplied for each EMS; additional details of the test vehicle
used to generate each calibration can be found in the 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 good starting point and can save
considerable time and money, it will not replace the need to tune the EMS for your specific
application. AEM startup calibrations are not intended to be driven aggressively before
tuning. We strongly recommend that every EMS be tuned 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 process; be warned that using your
vehicle as a learning platform can damage your engine, your vehicle, and your EMS.

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 location of the ECU on the 1G
DSM vehicles is behind the radio in the center console.
b) Carefully disconnect the wiring harness from the ECU. 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 body, and set them aside. Do
not destroy or discard the factory ECU, as it can be reinstalled easily for street use
and troubleshooting.
3) Install the AEM Engine Management System
a) Plug the factory wiring harness into the AEM EMS and 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 you connect to a Series 2 EMS with
an onboard USB port. When the Series 2 EMS is connected to the PC’s USB port
and receiving power from the vehicle, the “Found New Hardware” window will
appear. Select “Install from a list of specific location (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 matches the vehicle’s configuration to
be tuned. Check the Notes section of the calibration 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\Mitsubishi-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
less than 0.2% or greater than 99.8%, this is considered a sensor error and may
cause some functions including idle feedback and acceleration fuel to operate
incorrectly.
4) Ready to begin tuning the vehicle.
a) Before starting the engine, verify that the fuel pump runs for a couple of seconds
when the key is turned on and there is sufficient pressure 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 atmospheric pressure correctly.
b) Start the engine and make whatever adjustments may be needed to sustain a safe
and reasonably smooth idle. Verify the ignition timing: 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 selected.
c) Note: This calibration needs to be properly tuned before driving the vehicle. It is
intended for racing vehicles and may not operate smoothly 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 lacking, 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, measure ECU pinout voltages,
replace recently-added or untested components with known-good spares. Check
that all EMS sensor inputs measure realistic temperature 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. This indicates that the EMS has
detected the expected cam and crank signals; if Stat Sync’d does not turn on,
monitor the Crank Tooth Period and T2PER channels which indicate the time
between pulses on the Crank and T2 (Cam) signals. Both of these channels should
respond when the engine is cranking, if either signal 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 pressed this usually indicates that
there is a problem with the MAP sensor wiring or software calibration (when the
EMS detects that the MAP Volts are above or below the min/max limits it will run in
a failsafe mode using the TPS-to-Load table to generate an artificial Engine Load
signal using the Throttle input). This may allow the 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-
6300 EMS has been designed to accept 12V power on this switched input. If users desire
to re-wire a new switch to trigger the Switch 2 input the switch should connect to 12V
power when the switch is on. The pin can be left floating (disconnected) when the switch
is off, it is not required to send ground to this pin.
**All other switch input pins must connect to ground; 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.
***Idle control valve wiring is different for 1990 vs 1991+ models (pins 67, 68), please use
appropriate base calibration or change the (Idle Invert) option until your ISCV operates
properly.
The function of the following pins have been changed from the original 30-1300 EMS,
please see pinout chart for more info:
7, 13, 14, 73, 74, 109

Primary Load Sensor, EMS Fuel Strategy
The factory MAF (mass air flow) sensor can be removed 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 higher (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 sensor downstream of the intercooler to
accurately measure charge temperatures.
The factory Mass Air Flow and Intake Air Temperature sensors can be used as the
primary load input for the AEM EMS if desired. Please check the Notes section of each
calibration for more info about the vehicle setup and fuel strategy that calibration was
configured to use.
EMS Fuel Map, Boost Fuel Trim Table
The 30-6300 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 the manifold pressure is half as high; this
should help simplify the tuning process for different 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 installed
or if the Load breakpoints are adjusted. The Boost Fuel Correct value should be set to -90
at 10kPa, 0 at 100 kPa, +100 at 200 kPa, +200 at 300 kPa, etc…

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 injectors. The factory Mitsubishi wiring
harness contains a resistor pack to prevent excessive current when using low-impedance
injectors with the stock ECU. With the 30-6300 installed, users can elect to remove and
bypass the OEM resistor pack for more precise control 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 has been removed and bypassed, please
choose the correct battery offset for your injectors using the Setup Wizard. Most battery
offset wizard configurations will specify <P&H DRIVER> if they are intended for use
without a resistor pack.
Wiring accessories to the EMS:
Please follow this suggested wiring diagram when adding accessories such as UEGO
gauges, MAP sensors, IAT sensors, or switches for use with the EMS. Note that wire
polarity is not important for the Air Temperature sensor.
