Capabilities

Built for drivers who study the data

Every fast driver knows what the telemetry says. DeltaCoach puts it in your ear.

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.

What drivers are saying

Real feedback from drivers who got access early.

★★★★★

"I've been chasing half a second at Spa for months. First session with DeltaCoach and Gordon told me exactly where I was losing it — T1 entry and Raidillon mid-corner. Fixed both by lap 10. Genuinely useful."

MK
Mike K.
iRacing driver · GT3, Endurance Series
★★★★★

"The voice coaching is on point — it doesn't yell at you every corner, just pings you when something's actually wrong. Feels like having a real engineer in the headset. The debrief screen is clean too."

SL
Sarah L.
iRacing driver · Formula C, league racer
★★★★★

"I run a 12-person league and we've been using this in beta for test sessions. The corner-by-corner breakdown made our post-race debriefs 10x more useful. Everyone's actually looking at data now."

FAQ

Your engineer has answers.

Q01 What sims does DeltaCoach support? +
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.
Q02 Does it work in VR? +
Yes — the voice coaching works in VR since it's audio only. A full Quest overlay is in development. If you're running iRacing in VR and want early access, jump in the Discord.
Q03 Is it really free? +
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.
Q04 What telemetry data does it use? +
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.
Q05 How does the priority corner system work? +
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.
Q06 Do I need extra software or hardware? +
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.
