Safety 3rd: Defeating Chevy StabiliTrak for Electric Vehicle Track Racing
Eric Gershman reverse engineers Chevy Bolt and Spark EV CAN buses to defeat StabiliTrak Electronic Stability Control, unlocking full track racing performance.
Summary
The Challenge of Electronic Stability Control in Track Racing
Modern electric vehicles enforce rigid Electronic Stability Control (ESC / StabiliTrak) systems that cut electric motor torque and apply brakes when tires slip on a race track.
Reverse Engineering the Chevy Bolt and Spark EV CAN Buses
Eric Gershman captures and analyzes in-vehicle CAN bus traffic between the brake control module, steering angle sensor, and motor inverter.
Designing the CAN Interceptor and Spoofing Hardware
Gershman builds a custom microcontroller CAN bridge that intercepts yaw rate and wheel speed messages, spoofing stable telemetry to disable ESC interventions.
Dyno and Track Testing Results
The presentation showcases track testing results, proving full driver throttle control and demonstrating safe automotive hardware modification practices.
