OVERVIEW

The 30-3508 AEM Infinity Adapter Kit is designed for the 2000–2005 Honda S2000. These models include
all 2.0L (AP1) engines as well as the early 2.2L (AP2) engines with a cable driven throttle body. This is a
true standalone system that eliminates the use of the factory ECU. The use of this adapter makes the kit
“plug and play” so no cutting or splicing wires is necessary. The base configuration files available for the
Infinity EMS are starting points only and will need to be modified for every specific application.

The available AEM Infinity EMS part numbers for this adapter kit are:

30-7106 INFINITY-6
30-7108 INFINITY-8h

GETTING STARTED

Refer to the 10-7100 for EMS 30-7100 Infinity Quick Start Guide for additional information on getting
the engine started with the Infinity EMS. Base sessions are located in C:\Documents\AEM\Infinity Tuner
\Sessions\Base Sessions

DOWNLOADABLE FILES

Files can be downloaded from www.aeminfinity.com. An experienced tuner must be available to configure
and manipulate the data before driving can commence. The Quick Start Guide and Full Manual describe

The primary difference between the 30-7106 Infinity-6 and 30-7108 Infinity-8h is that the 8h lacks Peak
& Hold injector drivers to run low impedance fuel injectors. High impedance (saturated, high-z) fuel
injectors must be used with the Infinity-8h.

The Infinity-6 and Infinity-8h share a common pinout with the exception of four pins where the Infinity-8h
has two each additional fuel injector and ignition coil drivers. Due to the additional fuel injector and
ignition coil drivers, the 8h has two fewer digital inputs and lowside outputs. Use of this harness with an
Infinity-8h will require slight modification and will result in loss of some plug and play function- OEM
Coolant Gauge, Malfunction Indicator Light, and Brake Switch input.

INFINITY CONNECTORS

The AEM Infinity EMS uses the MX123 Sealed Connection System
from Molex. Refer to the 10-7100 for EMS 30-7100 Infinity Quick
Start Guide for details on connector assembly and handling.

AEM strongly recommends that users become familiar with the
proper tools and procedures for working with these high density
connectors before attempting any modifications. The entire Molex
MX123 User Manual can be downloaded direct from Molex at:

INFINITY ADAPTER HARNESS

Included with the 2000–2005 Honda S2000 kit is an adapter harness. This is used to make the
connection between the AEM Infinity EMS and the Honda wiring harness plug and play. This is depicted
below with the 80-pin connector and the Honda header. There are also a few other integrated connectors
within this harness described below.

The gray Deutsch 6P DTM “Lambda #1” connector is for connecting a UEGO wideband Bosch LSU4.2
sensor (AEM 30-2001). The UEGO extension harness (AEM 30-3600) mates the adapter harness to the
sensor.

The gray Deutsch 4P DTM connector is used for “AEMNet”. AEMNet is an open architecture based on
CAN 2.0 which provides the ability for multiple enabled devices, such as dashboards, data loggers, etc.,
to easily communicate with one another through two twisted cables (CAN+/CAN-).

The black Delphi 2-pin “Flash Enable” connector is used for secondary hardware flashing. The included
shunt connector jumps the 2 wires together. Once initially flashed, the EMS is normally upgraded in the
software, not using this connector.

The gray Deutsch 12P DTM “Auxiliary” connector
(shown below) is used to adapt many common
ancillary inputs and outputs easily. Included in the kit
are a DTM 12P mating connector, 12 DTM terminals,
and a DTM 12P wedgelock. If used, these
components will need to be terminated by the installer
or end user with 16–22awg wire (not included). Note:
The pin numbering is molded into the connector, as
shown.

DASHBOARD

The AEM Infinity EMS for the 2000–2005 Honda S2000 drives the Tachometer, Coolant Temperature
Gauge, and the CEL (Check Engine Light). Shown below are the AP1 and AP2 gauge clusters.

Rather than OBD2 diagnostics, the CEL light is now dedicated to the AEM “MILOutput” feature. The
AEM MILOutput activates if any 1 of the following inputs are in an error state: air temp, baro pressure,
coolant temp, exhaust back pressure, fuel pressure, UEGO #1, UEGO #2, MAF analog, MAF digital,
MAP, oil pressure, or throttle position. If any of these sensors are not used, they should be turned OFF
in the Wizard to avoid any false readings. To activate the MILOutput feature, go to the Wizard and check
“Enable MIL Output” in Diagnostics.

The coolant temp gauge is ECU
driven by a 5V 30ms pulse with a
period that varies with ECT
voltage, as shown. It is pre­calibrated using a combination of
the LS6_Freq [Hz] 1-axis table
and the LS6_Duty [%] 2-axis
table.

2000–2005 Honda S2000

5

Similarly, the Honda S2000 gauge
cluster’s tachometer is also driven by
the ECU, as shown. However, compared
to the coolant temperature gauge, this
signal is very elementary as it simply
varies frequency with engine speed.

The Honda S2000 tachometer is pre­calibrated using a combination of the
LS5_Freq [Hz] 1-axis table and the
LS5_Duty [%] 2-axis table.

First, make sure the Honda CD Player
activation code is recorded and also take
note of the radio presets. Next, open the
hood and disconnect the battery. Remember
to set the clock when reconnecting the
battery.

The stock ECU is located on the left-side
kick panel, as shown. Pop off and remove the
door sill (not pictured) and kick panel cover,
as shown.

Carefully unplug the 3 ECU connectors by
depressing the “thumb” lock on each
connector. Avoid excessive stress or pulling
on the wires, as this may damage the
harness.

To remove the ECU, unscrew the two
mounting M6 bolts from the mounting
bosses (circled in blue) using a 10mm
socket wrench. These mounting bosses
will not be reused.

As depicted in the picture, the sheet
metal surface in the ECU location is not
entirely flat. However, the included
adhesive hook and loop (Velcro) will still
be used to hold the Infinity EMS in place
while 1 of the OEM ECU bolts will be
reused to secure it to the spare M6
mounting boss, circled in red.

Step 3

Attach one side of the Velcro to the
back of the EMS and the other to the
chassis, as shown. Loosely screw the
OEM ECU bolt into the spare boss,
shown in red.

Attach the AEM 80-pin connector to the
EMS. Secure the Infinity connector by
sliding the red locking tab.

Slide the EMS all the way up until the
adapter harness contours around the top
side of the kick panel area. The OEM
ECU bolt should just be present on the
bottom side of the EMS.

Position the EMS onto the hook and
loop strip adhered to the chassis.

Move the EMS so half of the OEM ECU
bolt’s washer locks onto the EMS
mounting tab’s outer edge, as shown.
Tighten this bolt.

Next, connect the three OEM Honda
ECU connectors to the Honda header
found in the AEM adapter. Connect the
included mini USB communication cable
to the EMS.

If there are to be any AEMnet devices
that will be daisy-chained to the Infinity
EMS, secure it to the AEM adapter’s 4P
Deutsch connector.

If a wideband UEGO sensor was
purchased, put the car on a vehicle lift
(or jack stands).

Weld in a bung or use an existing O2
sensor bung that is pre catalytic
converter for optimal accuracy.

Use a 7/8” wrench to install the
wideband UEGO sensor (OEM location
shown).

The UEGO extension harness (sold
separately) should be routed away from
moving parts and should not come in
contact with excessively hot objects.

To get the UEGO extension harness into
the cockpit, use the factory grommet on
the left side firewall. RHD vehicles will
differ.

Pull grommet from firewall. Cut a small
slit in grommet and push Deutsch
connector through. Reattach grommet to
firewall. Mate extension harness to the
Deutsch connector found in the AEM
adapter.

If any of the auxiliary connections are to
be installed now is the time to assemble
these.

Reconnect the battery, and connect to
the Infinity Tuner software. After all of the
components are verified, reinstall the
kick panel and door sill.
