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\Honda - Acura\

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.

• OE Speedometer Functionality

Please note that the 30-6051 EMS is configured to drive the original 1996-2000
Honda Civic speedometer by outputting the appropriate signal on pin A9. This
signal is calibrated to use the OE Honda Civic dashboard, replacing the OE
speedometer with one from a different vehicle may change the behavior of the
gauge.

• Engine Wiring Harnesses, ‘swapped’ engine installations

It would be very wise to double-check that the pinout destinations for the circuits is
accurate to the provided documentation. This is especially true if the vehicle
contains a ‘swapped’ engine or if the wiring harness has been cut, spliced,
soldered, tapped or modified in any manner. It is the user’s responsibility to check
that the wiring on the vehicle matches the pinout chart in this document. AEM will
not be held responsible for loss or damage that can occur if the EMS is installed in
a vehicle in which the wiring harness does not match the AEM-supplied pinout
chart!

• EMS Fuel Map, Boost Fuel Trim Table

The 30-6051 calibration maps provided do not utilize the “Boost Fuel Trim Table” to

provide a 1:1 fuel compensation below atmospheric pressure since the calibration
was created on a naturally aspirated vehicle (A calibration is provided above 100

kPa). To use this table, the “Boost Fuel Trim Table” should be 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 Trim value should
be set to -90 at 10kPa, 0 at 100 kPa, +100 at 200 kPa, +200 at 300 kPa, etc…

• AEM EMS coil/injector differences from original Honda ECU:

The AEM EMS fires cylinders based on a different numbering scheme than the
original ECU. The chart below shows how the original cylinder numbers correspond
to the EMS coil/injector numbers. This is configured in the base calibration already
and is shown in the pinout tables later in this document.

Vehicle cylinder number AEM EMS injector number AEM EMS coil number

1 1 1
2 4 4
3 5 5
4 3 3
5 2 2
6 6 6

Wiring accessories to the EMS:

Please follow this suggested wiring diagram when adding/retaining original accessories such as the speedometer, reverse lockout,
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.

1) Install AEMTuner softw are 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 Acura

Integra, Acura CL/TL, Honda Accord, and Honda Civic vehicles is behind the kick­panel on the passenger side of the vehicle.

b) Carefully disconnect the wiring harness from the ECU. Avoid excessive stress or

pulling on the wires, as this may damage the wiring harness. All connectors must 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 original ECU, as it can be reinstalled easily for street use
and troubleshooting.

3) Repin appropriate ECU pins

a) For this application there is the potential need to repin some ECU pins. For the

tested application only one pin was added. Since there was no reverse lockout
solenoid activation on the automatic wiring harness, this pin was placed on ECU
connector pin A3.

b) Locate a small screwdriver (a precision 1.5mm wide flathead screwdriver is

recommended) and carefully pry white plastic retainer using both slots in the
retainer so it disengages vertically about 1mm as shown in the following pictures:
