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.

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:
Page 5 of 15
Figure above shows how plastic retainer will look when disengaged
c) Next remove the metal pin from the plastic connector by lightly prying on the plastic
tabs that secure the metal pin in the plastic connector while pulling on the wire at
the same time as shown below. The first figure shows an example of the tab that
must be pried up to disengage the pin.
Page 6 of 15
4) 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) At the time these instructions were written, new EMS units do not require USB
drivers to be installed on the PC.
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\Honda - Acura\
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.
5) 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 to 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.

Crankshaft timing marks are not labeled for some vehicles. Consult the factory
service manual for more information. The diagram below shows labels for the
Honda/Acura V6. A points to the timing indicator and B points to the 10° before top
dead center mark.
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
6) 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.
