MAP-ECU

Introduction

Launched as the original model in the MAP-ECU lineup, the MAP-ECU (described in this article as MAP-ECU1) was developed to offer a streamlined solution for performance tuning enthusiasts. Designed to work as a piggyback engine control unit, the MAP-ECU1 focuses on enabling speed density tuning by eliminating the restrictive factory mass airflow (MAF) or Karman Vortex Frequency (KVF) sensors in many vehicles. It intercepts signals between the vehicle’s factory ECU and sensors, allowing for custom fuel delivery adjustments, thereby optimizing performance without fully replacing the OEM ECU.

Though limited in functionality compared to later models, the MAP-ECU provided a strong foundation for vehicle tuning in naturally aspirated applications, offering basic 2D mapping capabilities to modify airflow and fuel control. The MAP-ECU1 introduced the core functionality that would be expanded upon in later models, focusing on simplicity and ease of installation.

Historical Pricing Information

Pricing (circa 2005):

  • MAP-ECU 1 Kit: $895

Product Overview

The MAP-ECU1 (Manifold Absolute Pressure Electronic Control Unit) by Performance Motor Research is an aftermarket fuel tuning device designed for vehicles with factory ECUs that rely on mass airflow (MAF) or manifold absolute pressure (MAP) sensors. This product allows users to adjust fuel delivery and optimize engine performance for modified applications, such as forced induction systems.

Key Features

  • Real-Time Monitoring and Adjustments: Enables real-time monitoring and modification of MAP-ECU tables and settings, allowing users to adjust parameters on the fly.
  • User-Friendly Interface: Operates via the MAP-CAL software for Windows, providing a graphical dashboard, 3D graphing, and table-based tuning.
  • Logging Capabilities: Logs input and output data, including fuel adjustments, pressure readings, and throttle positions for post-session analysis.
  • Customizable Data Tables: Supports 2D and 3D table visualization, making it easy to configure fuel settings at different RPM and pressure levels.
  • Air/Fuel Ratio Support: Includes functionality to log air/fuel ratios for performance monitoring.

System Requirements

The MAP-ECU1 connects to a PC using a standard serial COM port and operates with the following configuration:

  • Baud Rate: 9600
  • Data Bits: 8
  • Stop Bit: 1
  • Parity: Even

Compatible with Microsoft Windows operating systems, including Windows 95, 98, NT, and 2000.

Installation and Setup

MAP-ECU1 installation involves connecting the device to the factory ECU using the included wiring harness. The MAP-CAL software, provided on CD, is installed on a PC to manage the device’s configuration. Once connected, users can load base maps or configure custom settings via the software’s interface.

Software Overview: MAP-CAL

MAP-CAL is the tuning software used to control the MAP-ECU1. It includes the following functionalities:

  • Dashboard View: Displays engine data and provides an overview of the system status.
  • 3D Graph Mode: Visualizes fuel and pressure adjustments in a three-dimensional format for easy tuning at various engine loads.
  • Table Mode: Allows precise adjustments across different RPM and MAP zones for customized fuel delivery.
  • Logging: Records input and output data, which can be saved for later analysis.

Tuning Capabilities

  • Fuel Delivery Control: Users can adjust fuel delivery across RPM and pressure ranges, allowing for efficient fuel management in forced induction or naturally aspirated engines.
  • Enrichment Tables: Includes tables for throttle position (TPS) and manifold pressure (MAP) enrichment, allowing smooth transitions during rapid throttle changes.
  • Switched Outputs: Configurable switched outputs enable control over additional devices, such as boost controllers or auxiliary injectors.
  • Auto-Learn Function: The MAP-ECU1 can automatically adjust fuel maps in real-time, capturing optimal settings for different driving conditions.

Compatibility

The MAP-ECU1 is designed to work with a range of factory ECUs that use MAF or MAP sensors. It provides flexibility for a variety of vehicle modifications, particularly beneficial for vehicles equipped with turbochargers or superchargers where precise fuel control is essential.
