Project Timeline

Sep 2025 - Current

OVERVIEW

The first physical prototype of the wiring harness for the 2026 Formula uOttawa racecar being installed for testing and verifcation on the 2025 Formula uOttawa racecar. The new 2026 wiring harness includes newly installed shock-travel sensors along each suspension brace, wheelspeed sensors, brake temperature sensors, engine knock sensors, and new mounts for additional micro-controllers for CAN decoding, live data transmission, and an upcoming air-rake project in collaboration with Formula uOttawa Aero and Powertrain subteams. The harness is far from complete, with many signal connections yet to be fully validated and tested, and many additional refinements will be made to ensure the harness is regulation compliant and has enough foresight to simplify the redesign of the entire harness for the 2027 season.

HighlightS

December 2025: Identified key issues with Master Switch system, and greatly reduced complexity

Januarary 14, 2025: Discussion regarding swtich to EV will likely influence new changes to the harness to shift development into the direction of EV
