DIY Engine management system: Take full control of your car Ryan Ueltschi Eastern Kentucky University Department of Technology : NET Program
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.
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.
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
INTRODUCTION • Essential Theory: • Construct the physical system • Create a wiring harness • Install software on laptop • Install firmware on system • Wire in additional needed sensors • Install complete system into car • 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.
PROBLEM STATEMENT • Sub Problems • Fuel trim adjustments • Timing adjustments • Idle settings • Sensors
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.
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
Parts List • All from diyautotune.com • DB37 solder cup connector for MS3X - $5.00 • MegaSquirt Wiring Bundle - 23" Long - $15.00 • MegaSquirt - III MS3X Expansion Card - $90.00 • MegaSquirt - III w/PCB V3.0 - Unassembled Kit - $365.00 • MegaSquirt 3X Wiring Bundle - 23" long - $18.00 • 64 pin connector from mouser electronics - $20

RESULTS • A fully functional standalone Engine Management System
CONCLUSIONS • I am now able to incorporate a customizable engine management system in my car to monitor, data log, and make adjustments as needed. • Individual Learning: • Time Management • Project Planning • Increased knowledge in general electronics and automobile electronics • Soldering skills • Engine management/tuning
FUTURE WORK • Building these for future cars • Knowing how to tune electronic fuel injection engines, to help myself and others • Adding Bluetooth module • Connecting with an android device Contact: ryan_ueltschi@mymail.eku.edu
