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 each 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.aemelectronics.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.

 Engine Wiring Harnesses, ‘swapped’ engine installations

It would be very wise to double-check that the vehicle’s wiring harness destinations
match the pinout chart provided in this document. 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 30-6030 calibration maps provided utilize the “Boost Fuel Trim Table” to provide
a 1:1 fuel compensation above and below atmospheric pressure. 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…

 Honda Multiplex Control

The supported vehicles utilize a Multiplex system which communicates with many of
the vehicle’s control modules. The 30-6030 Series 2 EMS is different than the 30­1030 Series 1 EMS since it does not require the stock ECU to be installed for the
coolant temperature gauge and air conditioning switch to function.
If the AEM 30-6030 EMS is being installed into a different vehicle which does not use
the 01-05 Honda Multiplex system, there is no action required in either the software or
the hardware.
Note: When using the 30-6030 EMS, always use the 30-6030 specific Coolant Temp
Wizard calibration (note: this has been configured in all the 6030 startup calibrations).

Internal Logging
Since these vehicles do not have a constant 12V wire in the factory ECU harness, a
permanent 12V wire must be installed at Pin C1 for the Internal Log Memory. The pins
and connector in this kit can be used. Note: PC Logging can still be used to record
data from the EMS while the laptop is connected to the vehicle, it does not require
power at pin C1.

Check Engine Light

The Low Side 10 output (LS10) activates the Check Engine Light on the gauge
cluster. It is configured to activate at high RPM in the AEM startup calibrations; this
can be reconfigured by selecting Tools>>Configure Outputs.

Page 3 of 17

Variable Valve Control (VVC)
The VTEC output (pin B15, High Side 1 output on the EMS) switches from the low-lift

camshaft lobes to the high-lift camshaft lobes, similar to traditional Honda B-series engines.
This is controlled by the HS1 output (VTEC function) in the EMS, and can be adjusted in the
Tools>>Configure Outputs settings.

The i-VTEC output (pin B23, Injector 10 output on the EMS) advances the phase angle of
the intake camshaft; this will have effects similar to moving an adjustable intake cam gear.
This is controlled by the VVC 1 output; VVC position is monitored using the T3 input for
closed-loop feedback. The VVC settings can be adjusted in the VVC tab (which may be
hidden in the default AEM workspace).

This system is active on this EMS when used with the provided startup calibrations and can
be adjusted through the use of the ‘VVC 1 Target’ map. Adjustments to the intake cam timing

are made by changing the values in the ‘VVC 1 Target’ map per Engine RPM and Engine

Load. The values in the ‘VVC 1 Target’ map can vary from 0 degrees for zero intake cam

advance to 50 degrees for full intake cam advance.

Please note that the VVC Target angle for best power output will depend on the VTEC
settings, and vice-versa. If VTEC settings are adjusted it would be wise to adjust the VVC
Target map as well to ensure best power at all engine speeds.

WARNING:
Improper use of the Variable Valve Control (VVC) in the AEMTuner software can lead to
engine failure with certain setups!

Be very careful when building or tuning ‘hybrid’ engine combinations or using aftermarket
engine internals. OEM engines and camshafts are designed and manufactured in such a
way that the intake valves cannot be crashed into the pistons or exhaust valves regardless of
VVC advance angle and/or VTEC settings. It is NOT recommended to build setups that will
allow the intake valves to be crashed into the pistons or exhaust valves by adjusting settings
in the EMS!

Wiring accessories to the EMS

Please follow this suggested wiring diagram when adding new accessories and
retaining original accessories such as the multiplex coolant temperature gauge, air
conditioning switch, 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.

The EMS functions assigned to certain pins have been changed and no longer match the 30­1030 EMS. Unless otherwise noted, the following pins and functions will need to be manually
reconfigured after using AEMTuner to convert a V1.19 30-1030, Series 1 EMS calibration for
use with the 30-6030 Series 2 hardware.

30-1030 (Series 1) vs 30-6030 (Series 2) EMS differences:

Page 5 of 17

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 found at www.aemelectronics.com
Series 2 units are not supported by the older AEMPro tuning software.

2) Remove the Stock Engine Control Unit

a) Disconnect negative terminal from battery
b) Access the stock Engine Control Unit (ECU). The location of the ECU on the Acura

RSX, Honda Civic, and Honda CR-V vehicles is on the passenger side of the vehicle
behind the glove box.

Acura RSX Honda Civic Si

c) 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.

d) 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 ECU pins (only necessary if adding or relocating ECU pins)

a) 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:

Screwdriver lifts here Plastic retaining mechanism after lifting

Page 6 of 17

b) 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.

Pry this tab up to release the pin While prying tab up, gently pull pin back

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) Reconnect the negative battery terminal.
c) Plug the communications cable into the EMS and into your PC.
d) Turn the ignition on, but do not attempt to start the engine.
e) At the time these instructions were written, new EMS units do not require USB drivers

to be installed on the PC. The EMS will automatically be detected as a human
interface device (HID).

f) 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\

g) 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.

Page 7 of 17

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 original
timing marks. “A” points to the timing indicator and “B” points to the red mark that is
located 8° before top dead center.

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.

Sufficient battery voltage during cranking (starting)
Having enough battery voltage when you crank over your vehicle is critical to the
operation of your vehicle and your AEM EMS. For the EMS to function properly, the
battery voltage must remain at or above 8 Volts when the vehicle is first starting. This
is the time when your electrical system will be worked its hardest and be at its lowest
voltage. If you are connected to your Series 2 EMS with a USB communications
cable, and you experience disconnecting while the vehicle is cranking, the reason
may be a battery voltage of less than 8 volts. If this is the case, you can confirm this
by connecting with a serial cable (a serial adapter may be required if your computer is
not equipped with a serial port) and check in the AEMTuner software for a Channel

called “Run Time”. “Run Time” is the amount of time, in seconds, that the EMS has

been turned on for. If you notice that this Channel goes to zero while the EMS is
communicating with the computer and the vehicle is being cranked, that means the
EMS has had lower than 8 Volts at some point and has reset the system. A thorough
wiring check may reveal a large voltage drop causing this problem, or it may simply
be the need for a new or a larger battery.
