Congratulations! You have just purchased the finest Engine Management system for your car at any price! 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 an all new 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. 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. The AEMPro software is configured to work with the factory sensors and equipment, so that there is no need for expensive or hard to find sensors, making replacement and repairs as simple as with an unmodified car. For stock and some slightly modified cars, the AEMPro software will be preprogrammed with a set of base parameters, providing a starting point for individual tuning. For more heavily modified cars, the EMS has many spare inputs and outputs allowing the elimination of separate rev-limiters, boost controllers, nitrous controllers, and fuel computers. It will also allow programmable control over all automatic transmission functions, and includes a configurable onboard data logger capable of recording 512kb of information. Every EMS comes with all functions installed and activated, and there are no expensive options or upgrades to be performed. The installation of the AEM ECU on the 1996-2002 Dodge Viper V-10 uses the stock sensors and actuators. The base map is automatically installed in the base calibrations directory in the AEMPro directory on your computer. It is named 1500 Stock MAP.VX.XX.cal. Full details of the test vehicle used to generate this map can be found in the files notes section. However, while the base map is a good starting point and may save you considerable time and money, it will not replace the need to tune your specific application. It is not intended to be driven aggressively. Ignoring this can and will damage your engine. Please visit the AEM EMS Tech Forum at http://www.aempower.com/bbs and register your EMS before you start to use it. Make sure you enter your EMS serial number when you register as doing this grants access to the calibration files. We always post the most current strategy release, PC Software and base calibrations online. On the forum, you will find many helpful hints/tips to make your EMS perform it’s best. Also, we may make available EMS maps for engines running speed density, larger turbo, etc… NOTE: IF YOUR VEHICLE CURRENTLY USES REAR O2 SENSOR SIMULATORS, THEY MUST BE UNPLUGGED OR REMOVED BEFORE INSTALLING THE AEM EMS. THE SIMULATORS CREATE NOISE ON THE 0-5V SENSOR GROUND AND WILL ADVERSELY AFFECT ENGINE OPERATION. Read and understand these instructions BEFORE attempting to install this product. 1) Removing the Stock Engine Control Unit

Page 2 of 12

a) Access the stock Engine Control Unit (PCM). The location of the PCM on the Dodge Viper is inside the engine compartment on the driver’s side below the battery charging location.

b) Remove the factory heatshield by removing the four 8 mm bolts and two screws. c) Carefully disconnect the wiring harness from the PCM. Avoid excessive stress or

pulling on the wires, as this may damage the wiring harness. Do not cut any of the wires in the factory wiring harness to remove them.

d) Remove the fasteners securing the PCM to the vehicle, and set it aside. Do not destroy or discard the factory PCM.

2) Installing and routing the AEM UEGO Sensors a) Remove the forward most O2 sensors and replace them with the supplied UEGO

sensors. b) Install the supplied UEGO harness by plugging the single 14 terminal connector

into the ECU and each 6 terminal connector into the UEGO sensor connectors. The long lead is intended for installation of the passengers side forward most O2 sensor.

3) 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 –10 screws and spacers.

b) Install the supplied AEM CD and open the AEMPro software. c) Turn the ignition “on” but do not attempt to start the engine. d) Go to: “ECU | Send New Calibration”. Upload the base calibration file (.cal) that

most closely matches the vehicle’s configuration to be tuned. Full details of the test vehicle used to generate each map can be found in the “Notes” section in the “Setup” window of the AEMPro software. The base maps can be found in the Dodge folder located in: “My Computer | Local Disk (C:) | Program Files | AEM | AEMPro | Startup Calibrations”

e) Set the throttle range: Select the “Configure” drop down menu, then “ECU Setup | Set Throttle Range” and then follow the instructions given on the screen.

f) Calibrate the lambda sensor channel: With the ignition “on” and the sensor unplugged, change the “O2 #1 Gain” (“Setup | Sensors | Oxygen Sensor | Oxygen Sensor #1 | Options - O2 Sensor #1”) until the “O2 #1 Volts” parameter displays 4.00 Volts (+/- 0.02 Volts). This should yield an “O2 #1 Gain” near 1.3. Set the appropriate UEGO calibration: Enter the calibration on page 8 of this manual into Setup | Sensors | Oxygen Sensors | Oxygen Sensor #1 | O2 Sensor #1 Cal Table. Note, this is different than that used for the external AEM UEGO sensor.

4) Stock PCM and EEM function: a) The Viper Coupe and Roadster utilize an Electronic Entry Module (EEM). The

Entry Module provides remote keyless entry functions as well as vehicle theft alarm functions. Installation of the AEM EMS removes communication between the Chrysler PCM and the EEM. Because of this, the red LED on top of the dash will be lit while the EMS is installed.

b) Alarm function is not disabled with the EMS installed. The effect from this

condition is that the automatic door locks will no longer function as they would with the stock PCM installed. If the key is left in the RUN position and the doors are closed, the automatic locks will be activated. Under these conditions, the

Page 3 of 12

doors can be opened from inside the vehicle by using the manual release latches ONLY. The door opening levers will not work. With the key in the OFF position, the door opening levers will function correctly from inside or outside the vehicle.

c) THE VEHICLE CANNOT BE ENTERED FROM THE OUTSIDE IF THE KEYS

ARE LEFT IN THE RUN POSITION.

YOU MUST MAINTAIN THE FACTORY PCM AFTER INSTALLING THE AEM EMS FOR PROPER COMMUNICATION OVER THE CCD BUS AND OPERATION OF THE EEM. IF THIS IS NOT DONE, THE DOORS WILL NOT BE ABLE TO BE OPENED USING THE DOOR OPENING LEVERS WITH THE KEY IN THE RUN POSITION.

5) PCM Relocation:

a) Remove the passenger side knee panel as shown.

b) Remove the

passenger side knee panel support brace ashown.

s

c) Repeat this same

procedure on the driver’s side as well.

Page 4 of 12

d) Plug supplied harness connectors into PCM and install the controller into the pocket under the dash as shown. Secure controller with Velcro.

e) Feed harness across toward the driver’s side behind console. To gain access to the EEM, remove the rubber retaining strap holding it and allow it to hang down.

f) Five connections are

required at the EEM. Tap the circuits as shown in the following table.

g) Soldered and heat shrinked connections are recommended for each circuit tap as shown.

h) When all required

connections are complete, re-install the EEM using the rubber retaining strap.

i) Secure all wires under the dash and be sure to avoid any sharp edges or

corners.

j) Re-install the knee panel support braces and knee panels on both sides of the vehicle.

6) Idle Control Tuning

a) The Viper idle air control motor is sometimes susceptible to drift and/or sticking. If your idle control hangs abnormally high or low during operation, turn the key to the ON position and wait approximately 10 seconds before starting. The EMS will reset the idle motor and store the new position references.

Notes:

The sensor should not be subject to mechanical or thermal shock or it may be damaged. The sensor is not designed for operation on leaded fuels, doing so will dramatically shorten sensor life. Long term running in the rich region (Lambda < 0.95) will shorten sensor life. High exhaust temperatures (over 850C) will shorten sensor life. Engine oil consumption at a rate greater than 1 quart per 1,000 miles will shorten sensor life. Do not run the engine with the UEGO sensor installed without power applied to the controller and the sensor plugged in.
