The loop

The pit-wall workflow, automated.

Real engineers run a closed feedback loop with their drivers — test, talk, adjust, retest. Pace-ly runs that same loop, on your schedule.

STEP 01

Drive a session

Run laps in iRacing. The Pace-ly companion app reads telemetry in real time — throttle, brake, steering, gear, speed, suspension travel, all of it.

STEP 02

Describe how it felt

Plain language. "Loose on entry into T4." "Front pushing through the long right." No need to translate to engineering-speak.

STEP 03

Get an engineer's answer

Pace-ly cross-references your feedback with the telemetry trace and recommends exact changes — spring rates, ARB clicks, tyre pressures.

STEP 04

Apply, retest, iterate

Load the proposed setup, run another stint, and report back. The loop tightens as the AI learns the car, the track and your style.

Capabilities · with or without the AI

Engineering-grade tools, driver-friendly UI.

The AI is one way in — lap compare, per-corner analysis and the session library work on their own, no prompt required. Every feature answers one question: where is the lap time, and how do we go and get it?

AI race engineer chat

Two roles in one chat — a Mechanic that reads the trace and proposes setup changes, and a Driver Coach for technique. Tuned for motorsport, grounded in your own laps.

Live telemetry capture

The Pace-ly Client reads iRacing's shared memory at 60 Hz. Throttle, brake, steering, slip, suspension travel — every session auto-saved, nothing lost. Or upload an .ibt.

Setup garage + .sto sync

A versioned setup library you can fork and tweak. Push loadable .sto files straight into the iRacing garage, and capture the as-run setup from any session.

Session library

Every stint indexed by track, car and layout, searchable by name, file or tag, with a track-temp filter. Reopen today's GT3 run at Spa or last month's PB in two clicks.

Per-corner analysis

Brake-zone segmentation, apex-speed deltas, trail-braking and exit-throttle fractions — corner by corner, on a GPS-driven line and track map.

Lap & video compare

Side-by-side delta charts between any two laps, plus one lap of in-sim video synced to the trace — hover to seek, play to sweep the cursor down the lap.

And, since you're here · included

Fifteen live overlays, in the box.

Delta, fuel, standings, relatives, track map and inputs are just the start — there's also weather, wind, flags, spotter, last laps, pit assist, pit projection, ECU and a team HUD. The full stack, no add-ons. Drag anywhere, hide on a hotkey.

Inside the conversation

Real feedback. Real changes.

This is how a typical exchange runs — driver feedback, telemetry-grounded analysis, an applied setup diff.

Car feels loose on entry into Les Combes. I'm trail-braking and the rear just steps out — happened on lap 7 and lap 11. Mid-corner is fine but I'm losing the exit because I'm catching the slide.

Pace-ly · race engineer
Confirmed — your trail-brake into T8 is 0.42s longer than the laps that stuck. Telemetry shows the rear inside wheel unloading 18% earlier than the front, which lines up with the snap you're describing.

Two changes I'd run together:
· Soften the rear ARB by one click (P5 → P4) to keep the inside rear loaded under brakes.
· Add +2 clicks of low-speed rebound on the rear dampers to slow the weight transfer.

Driving-wise: ease off the brake about 20m earlier, carry the speed in. You're scrubbing on entry trying to recover from the snap — fix the car first, then re-set your reference.

Questions

Things drivers ask first.

None. Pace-ly reads from iRacing's official shared-memory telemetry API — the same one the in-game black box uses. No DLL injection, no memory hacking, nothing that could affect your iRating or get you flagged. The companion app is sandboxed and runs alongside the sim.
Pace-ly works with every official iRacing car and track. The setup-coach has the most depth on the popular GT3, GTP, formula, and oval series, but the underlying telemetry analysis runs on anything in the service — if iRacing logs it, we read it.
They're grounded in your actual telemetry, not a generic forum thread. Pace-ly cross-references your feedback against brake-zone, corner-apex, and suspension data from your own laps. We're not promising you'll be Max Verstappen — we're promising the same kind of methodical, data-driven feedback a real engineer would give.
Pace-ly reads the as-run setup straight from your telemetry, so usually there's nothing to import — the mechanic reasons about the exact car you drove. Beyond that there's a setup garage: fork and tweak setups, capture them from any session, and push loadable .sto files straight back into the iRacing garage.
Both. Pick any two laps from your session library for a side-by-side delta chart, sector splits and a track map of where the time went. You can also record one lap of in-sim video that syncs to the trace — hover the chart to seek the footage, or hit play to sweep the cursor down the lap. Works for live laps and uploaded .ibt files alike.
Yes — Teams is built in. Spin up a workspace with roles, chat and an activity feed, share sessions, laps and setups to a shared garage, plan multi-driver stints with fuel and time estimates, and run a championship with events and a points leaderboard. It's all part of the same Pro plan.

Go faster, in fewer laps.

It all rides on one subscription — AI engineer, telemetry analysis, 15 overlays, the setup garage and team race-planning. Sign in with Discord and your session library starts the moment you're in.
