• Sponsored by RIT's Formula SAE Racing team,

this project is the second phase of several, which

is intended to continue and expand upon the

Engine Control Unit (ECU) project started by the

P07222 team.

• With an RIT developed engine management

system, which is going to replace the MoTeC's

M400 ECU, the formula team can significantly cut

costs and gain recognition for their uniqueness in

design at competition

Test Bench

Development

Board

• ECU modeled after MOTEC ECU.

• Pick up where the last team left off

• Debug the current design

• Propose a solution to fix the circuitry in the

prototype

• Test bench must have sensors that support ECU

operation

• Test bench must be representative of an actual

engine

• Should have outputs for proof of concept

• Should be easy to use and update

• Show that the ECU can be updated from the GUI

• Thorough testing must be completed before

placing on an engine

• Good documentation

•DC-DC Buck Converters

•Linear Voltage Regulator

•Injector Drivers

•Ignition Drivers

•Analog Input/Output

•Digital Input/Output

•Temperature Sensors

•Fan and Fuel Relays

• Written in C

• Texas Instruments TMS470 microcontroller.

• Functionality

• Read the sensors on the engine

• Determine the injection and ignition

signals from the fuel and ignition tables.

•Testing was done on the development board,

NI-USB 6229

LabView Interface

1.National Instruments Equipment

• NI-USB 6229

•Simulates sensors inputs

•Reads ECU’s Outputs

2.LabView Programs

• Phase I

•Signal Quality Testing

•Phase II

•Timing Testing

The purpose of the test bench is to verify the ECU proper functionality

through a data acquisition system.
