SDK
Live iRacing Integration
Connects directly to iRacing via the official SDK. Reads throttle, brake, steering, speed, and position in real time — no file exports, no delays.
Track Intelligence
Auto Track Detection
DeltaCoach recognises the track the moment you connect. 92 corners mapped across supported circuits — includes ENTRY, MID, and EXIT phase boundaries pre-loaded.
Analysis
Lap Delta Tracking
Compares your current lap against your best reference in real time. See exactly where you're gaining and where you're bleeding time — corner by corner.
Phase Detection
ENTRY / MID / EXIT
Every corner is split into three precision phases. Coaching and analysis targets the specific phase where the issue is — not just "you're slow here."
Focus System
Priority Corner Focus
After each session Gordon identifies your 3 weakest corners by average time loss. Next session, coaching prioritises exactly those corners.
Coaching
Brake & Throttle Analysis
Input trace analysis catches late braking, early lift, and throttle-timing errors. Gordon flags input mistakes at the moment they happen, not minutes later.

04 — FAQ

Your engineer has answers.

iRacing only for now. We're built on the iRacing SDK which gives us live, accurate telemetry. Support for other sims is on the roadmap, but we want to do iRacing right first.
Yes — coaching will be audio-first (voice delivery is in development), which suits VR perfectly. A full Quest overlay is also planned. If you're running iRacing in VR and want early access, jump in the Discord.
Yes, fully free during beta. No credit card, no trial limit, no feature-gating. We're in active development and want real drivers giving us real feedback.
DeltaCoach reads live telemetry via the official iRacing SDK — throttle position, brake pressure, steering angle, speed, track position, lap time, and sector splits. Nothing is sent off your machine without consent.
After each session, Gordon ranks every corner by your average time loss per lap. The three corners where you're consistently losing the most time are flagged as Priority Focus. Voice coaching in your next session will target those corners specifically.
Just iRacing and a browser. DeltaCoach runs as a lightweight app alongside your sim — no extra monitors required, no plugins. The debrief UI is browser-based so you can use it on any screen.

Put an engineer in your headset.
