OVERVIEW

The 30-3500 AEM Infinity Adapter Kit is designed for the 1993–1998 Toyota Supra MKIV Twin Turbo (manual transmission). 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:

30-7100 INFINITY-8 30-7101 INFINITY-10

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. Toyota Supra MKIV Twin Turbo 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 steps for logging in and registering at www.aeminfinity.com.

INFINITY CONNECTORS

The AEM Infinity EMS uses the MX123 Sealed Connection System from Molex. 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 1993–1998 Toyota Supra MKIV Twin Turbo kit is an adapter harness. This is used to make the connection between the AEM Infinity EMS and the Toyota wiring harness plug and play. This is depicted below with the 73-pin and 56-pin connectors and the Toyota header. There are also a few other integrated connectors.

ECU SETUP WIZARD

Important Application Specific Settings

Engine

In the Wizard Engine tab confirm the following:

Number of Cylinders = 6 Engine Cycle Type = 4 Stroke Ignition Type = Sequential (Coil On Plug) Firing Order = 1-5-3-6-2-4

Cam/Crank

In the Wizard Cam/Crank tab confirm the following:

Toyota Supra (1993–1998 Turbo)

Open the Advanced Setup tab and set the following:

Crank Noise Cancellation = 70 Cam 1 Noise Cancellation = 70

Add the 1-Axis Lookup Table VR_PwmDuty [%] to your layout. Set the following:

Ignition Sync

Add a text grid control to your layout and select the following channels. Make sure their values match the settings below for initial timing sync.

TrigOffset [degBTDC] = 23.00 CamSyncAdjustment = 11.00

See QuickStart Guide section Setup: Ignition Sync for instructions on timing sync.

Idle Stepper Max Steps

Go to Setup Wizard Idle page and confirm the following:

Idle Stepper Max Steps = 132

AC Input Switch

Go to Setup Wizard Input Function Assignment page and confirm the following:

AC Input Switch Setup = Analog17[V]

1993–1998 Toyota Supra MKIV Twin Turbo

Many Toyota, Mitsubishi, and other vehicles use an Idle Air Control Valve with a Unipolar Stepper Motor (6-pin connector) and MUST be modified. See instructions below. A Bipolar Stepper Motor (e.g., GM) will have a 4-pin connector and DOES NOT need to be modified.

*This info does not apply to vehicles that utilize IACV solenoids.

The 2 center pins (Black-Red wires) supply 12V power to the stepper motor in the factory setup, however these pins MUST BE DISCONNECTED before powering the AEM Infinity ECU.

P/N 30-3500

IDLE AIR CONTROL VALVE REQUIREMENTS

1993–1998 Toyota Supra MKIV Twin Turbo

Step 1: Disconnect connector from IACV housing and gently remove the retainer from the connector.

Step 2: Use a small flat-blade screwdriver/pick to move the terminal locks while pulling the Black-Red wires out from the backside of the connector.

Step 3: Use heat shrink to insulate both 12V wires, and then zip-tie the insulated wires to a nearby loom.

Step 4: Reinstall the retainer, and then plug the connector back into the IACV.

MAIN RELAY/FUEL PUMP SCHEMATIC

The 1993–1998 Toyota Supra Infinity patch harness requires a harness relay and fuel pump control to be wired exactly as pictured below. Failure to do so may result in an unresponsive ECU and/or a no-start condition.

Step 1: Remove the four ribs located near the center of the cover as highlighted below.

Step 2: Trim the center support leg as outlined. Test fit, note, and trim any additional areas required.

P/N 30-3500

ECU COVER MODIFICATIONS

It is recommend that the OEM ECU cover panel be modified and reinstalled with the AEM Infinity EMS when utilizing the mounting bracket. Failure to properly clearance and reinstall this panel (Toyota PN#55199-14020) could potentially result in damage to the ECU, adapter harness, ECU connectors and/ or USB cables and connectors.

Please note clearance modifications below. These modifications should be performed with a die grinder, 90-degree sander, or plastic shears.

INFINITY EMS INSTALLATION

Locate factory Engine Control Unit (ECU). Most ECU's are located in the passenger kick panel, behind the center console, or in the engine bay.

Step 1

Disconnect battery's negative cable.

Step 2

1993–1998 Toyota Supra MKIV Twin Turbo

Unplug factory harness plugs at ECU and remove factory ECU.

Step 3

P/N 30-3500

Step 4

Plug factory harness plugs into AEM Infinity Adapter Harness.

1993–1998 Toyota Supra MKIV Twin Turbo

Mount the Infinity ECU and connect Infinity connectors and USB cables.

P/N 30-3500

Step 5

Step 6

Run the USB cables to an easily accessible location.

Step 7

Reconnect the battery's negative cable.
