TRANSCRIPT
• 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.
