Virtual Motorsport Architect, Sim Rig Automation & Telemetry Systems.
Bridging championship real-world motorsport telemetry with virtual competition ecosystems. Pioneer of early iRacing leagues, co-producer of the first live sim racing broadcasts in history, and architect of modern autonomous sim rig automation, driver queue kiosks, and broadcast telemetry engines.
The Pioneer Pedigree: Architecting Virtual Motorsport From Day One
Before modern esports leagues, cloud APIs, or Twitch streaming suites existed, competitive online motorsport was raw code, custom IRC servers, and uncharted territory. PJ Losey built the communities, sanctioning rules, and broadcast director workflows that established early competitive sim racing.
iRacersResource & ISRA League
Founded and engineered iRacersResource (iracersresource.com) and the International Sim Racing Association (ISRA) (israleague.com). As early iRacing beta members joined the service in 2008, ISRA established organized multi-class championships (such as the ISRA Grand-Am Championship) and league governance years before iRacing introduced native in-game league tools.
- Pre-Native League Infrastructure: Organized multi-tier road and oval series with independent incident tracking, points matrices, and driver rulebooks.
- Setup & Resource Repository: Built iRacersResource as an early community hub for verified setups, car balance notes, lap analysis, and utility downloads.
- Independent Stewarding Workflow: Post-race telemetry and replay inspection protocols to review incidents, penalize unsportsmanlike contact, and preserve clean racing.
First Live iRacing Broadcasts
Involved in the first live multi-camera sim racing broadcasts alongside ProSimRacing TV (PSRTV / psrtv.com) and iLeagueRace (ileaguerace.com). Long before Twitch or modern streaming suites existed, PSRTV pioneered live video coverage of premier iRacing series (including the early World Championships and World Cup), pairing live TV-style director camera cuts with early VoIP commentary.
- Multi-Camera Virtual Director: Built spectator camera switching workflows and television-style tracking shots to deliver authentic broadcast race coverage.
- Automated Standings & Timing: Integrated with iLeagueRace (ileaguerace.com) for race statistics, championship points tracking, and event recaps.
- Foundational Esports Blueprint: Helped establish the live presentation standards that paved the way for modern virtual motorsport broadcasting.

Modern Engineering Stack: Autonomous Rig & Motorsport Infrastructure
GridPass
Digital Passports & Telemetry IdentityThe universal identity layer for vehicles, sim rigs, drivers, and paddock operations. GridPass turns disconnected simulators and physical track cars into verified digital assets with immutable records.
SimOS / SRCommander
Rig Automation & Session OrchestrationReal-time Python telemetry companion daemon and Electron session orchestration engine. Built with an automated state machine governing end-to-end commercial venue and event rig turnover with zero staff intervention.
ON_TRACK_IN_PITS vs ON_TRACK_MOVING. Clock stays paused in the pit stall and strictly begins countdown only when speed exceeds 1.0 m/s.i key), monitors coast deceleration to <1.0 m/s, holds Escape for 2.5s, logs lap telemetry to database, and auto-promotes the next driver.BroadcastOS & League Engine
Dynamic Overlays & Stewarding ToolsTurnkey esports graphics production and competition sanctioning backend. Eliminates clunky legacy broadcast tools with reactive, browser-based render layers built directly for OBS Studio and vMix.
Hardware Telemetry & Fabrication
Bare Silicon, CAN Bridges & Motion RigsBridging bare microcontroller silicon and Mil-Spec wiring with industrial direct-drive chassis. Bringing true motorsport electronics engineering to the sim cockpit.
The SimOS Telemetry Pipeline: Physics to Cloud in Sub-10ms
How high-frequency physics data travels from native simulation memory buffers through our multithreaded extraction daemons into hardware peripherals, driver HUDs, and broadcast streams.
Simulation Physics Engine
iRacing, Assetto Corsa, or rFactor 2 shared memory buffer updated at 60Hz to 360Hz.
SimOS Local Daemon
Multithreaded C++/Python daemon samples memory, filters noise, calculates deltas, and computes slip angle.
High-Speed Telemetry Bus
Local and cloud WebSockets / Redis PubSub stream JSON packets with sub-10ms delivery to subscribed nodes.
Client & Hardware Targets
Synchronous delivery to DDU dash, tactile transducers, BroadcastOS stream overlays, and GridPass registry.
Why Real Championship Engineers Build Superior Sim Platforms
Most sim software is built by generalist web developers who have never stood on a pit wall during a 24-hour endurance race or analyzed an IndyCar telemetry log under race pressure. PJ Losey brings proven trackside championship engineering directly to the virtual racing cockpit:
Honda Racing Corporation (HRC)
Trackside engine telemetry liaison for Indy 500 victory and multiple IndyCar championships. Experience with McLaren ATLAS, Cosworth Pi, and high-frequency sensor logging translates directly into sim telemetry fidelity.
NASA 25 Hours of Thunderhill Winner
Team Manager & Chief Electronics Engineer for the overall race winner. Designing systems that never crash under 25 hours of continuous punishment is the DNA behind our unattended sim rig daemons.
Siemens Proton Accelerator Lead
Clinical commissioning and electrical architecture for multi-million-dollar medical proton therapy accelerators. Zero tolerance for electrical noise, grounding loops, or EMI in high-torque direct-drive rigs.
