OUTLINE
This presentation will give a brief overview of my project. It will explain the presented problem and solution as well as the motivation, assumptions, and future work.
Pictures will be included for further understanding of the work I have completed.
3
MOTIVATION My automotive interests
mixed with my technology and electronics interests.
I wanted to challenge myself I wanted to further my
knowledge in general electronics and automotive electronics.
I needed an engine management system for my car.
4
INTRODUCTION My project covers both fields of
Electricity & Electronics and Computer Systems
I have been researching in plan to build one of these specific systems for well over a year Electronic components needed Wiring diagrams Sensors Software
5
INTRODUCTION
Essential Theory:I. Construct the physical systemII. Create a wiring harnessIII. Install software on laptopIV. Install firmware on systemV. Wire in additional needed
sensorsVI. Install complete system into carVII. Tune

PROBLEM STATEMENT
When an automobile’s engine becomes highly modified, the factory issued engine control unit (ECU) becomes insufficient for the engine’s requirements.
7
PROBLEM STATEMENT
Sub Problems Fuel trim adjustments Timing adjustments Idle settings Sensors
8
ASSUMPTIONS
To build: the user will have a working knowledge and/or willing to educate themselves in electronic components, electricity, soldering, printed circuit boards, wiring, and slight advanced workings of a computer.
9
ASSUMPTIONS
To use: the user must know general car engine knowledge and how they work and what the engine will need at a given point in time
Can hire someone to do the final tuning part.

PROPOSED SOLUTION In order to find a solution to my problem
I had to decide on an EMS Research, research, research Build one myself Buy a MegaSquirt DIY EFI kit from
www.diyautotune.com Buy the other components needed
specifically for my car Download/install software Assembly Testing and troubleshooting
