AEM Haltech Platinum Sport ECU to CD Dash Setup Guide

Introduction

This guide provides essential instructions for integrating Haltech Platinum Sport ECUs with AEM CD Dash displays, enabling comprehensive data monitoring for performance vehicles.

The AEM CD Dash is a high-resolution digital display unit that can show critical engine parameters. The accompanying image depicts the AEM CD Dash unit displaying real-time data such as RPM (179 MPH), Gear (3), Fuel Pressure (38.2 PSI), and Low Oil Pressure (@ 28 PSI). It is shown connected to a Haltech Platinum Sport ECU, the source of this CAN data.

Supported Devices

The AEM CD Dash is compatible with the following Haltech Platinum Sport ECU models:

• Platinum Sport 1000 ECU
• Platinum Sport 2000 ECU

CAN Bus Wiring

The AEM CD Dash is equipped with two CAN ports. For connecting third-party devices like the Haltech Platinum Sport ECU, AEM recommends utilizing AEM CAN Bus 2. The necessary connections are typically found within a 2-pin Deutsch DTM connector. On older vehicle harnesses, these connections might be present as an unterminated, twisted/shielded flying lead.

Platinum Sport Plug-In ECUs Wiring

• Haltech CAN Hi (Pin 7) should be connected to the AEM CD "CAN 2" Pin 1 (CAN 2+). This wire is typically gray and part of a twisted/shielded pair.
• Haltech CAN Lo (Pin 3) should be connected to the AEM CD "CAN 2" Pin 2 (CAN 2-). This wire is typically black and part of a twisted/shielded pair.

Consult the specific Haltech ECU documentation to determine if a terminating resistor is required at the ECU end of the connection.

A diagram illustrates the CAN connector on the rear of the ECU, clearly labeling Pin 3 as CAN Lo and Pin 7 as CAN Hi.

ECU Software Setup

To enable communication using the V2 protocol, the Haltech ECU must be running software version 1.11 or later. The software configuration steps are as follows:

1. Open the ECU Manager software.
2. Navigate to the "Setup" menu, then select "Main Setup".
3. Within the "Main Setup" screen, locate the "CAN Mode" option and select "Haltech CAN (Version 2)".

Supported Channels

The Haltech V2 protocol supports up to 103 unique channels, all of which can be transmitted to the AEM CD-7. Note that not all Haltech ECUs transmit values for every channel.

Layout Overview & CAN Setup

Users can create custom dash layouts using DashDesign by selecting "File" then "New". Alternatively, pre-designed layouts are available, which may include screens with blank CAN inputs. To utilize these, select "File" then "Open" and choose a setup file prefixed with descriptive text (e.g., "xzyblank.aemcd7").

To import a CAN setup into the display:

1. From the main DashDisplay menu, select SETUP, then DISPLAY.
2. In the dialog box that appears, navigate to and select the "CAN Receive" tab.

The Setup Editor window provides controls for configuring CAN communication parameters. The recommended settings for integrating the Haltech Platinum Sport ECU are:

• Show: Select "Port 2"
• Baudrate: Set to "1 Mbit/s"
• Termination Resistor: Set to "ON"
• Address Mask: Set to "OFF"
• M800 Support: Set to "OFF"

After configuring these settings, click the "Import CAN" button located on the lower left side of the editor. Select the relevant CAN setup file. The newly imported channels will then appear in the "Outputs" tab. These channels can be further customized by renaming, filtering, or manipulating them to suit specific needs.
