Pricing: Free Spotter tier; paid Purple Packs and Blue plan. Spotter includes the Quick Debrief; Purple adds PDF Engineering Reports; Blue adds unlimited sessions and Crew Rooms. Check pitdelta.co for current prices and limits. Platform: Web (any device); uses iRacing session files from Windows Best for: Drivers who want a next-stint job from telemetry without reading traces

PitDelta is a web-based iRacing telemetry debrief tool. Upload a session file and it turns the data into plain instructions: where you lose time by corner, and the one change to make next stint. Compare against a faster teammate, or put the crew in one room. Analysis is computed from telemetry and withheld when the evidence is weak.

Key Features

Upload iRacing session files — no desktop agent required
Corner-named time losses and one next-stint assignment
Metre-level instructions (brake point, throttle, speed carry)
Benchmark vs a faster driver: learnable pace vs pace you already have
Crew rooms for comparable teammate sessions
Quick Debrief card for Discord plus PDF Engineering Report
Evidence gates: weak signal is withheld, not guessed

What It Does

PitDelta turns iRacing telemetry into a plain-language debrief: where you lose time by corner, and the one change to make next stint. Upload one ibt session file for a Quick Debrief of your own laps, add a faster driver's file for a benchmark that splits the gap into pace you still need to learn versus pace you already have but do not repeat, or use a crew room to compare comparable sessions. Reports name time losses by corner, give metre-level instructions (brake later, carry more speed), and flag repeating habits that cost time in more than one zone. You get a shareable Quick Debrief card plus a PDF Engineering Report. PitDelta is not an AI coach: zone selection and practice assignments come from encoded rules. Weak or contradictory evidence is withheld rather than turned into confident advice.

Pros & Cons

Pros

Plain-language debrief instead of graphs
No install — drop a session file in the browser
Benchmark splits learnable gap from inconsistency
Withholds advice when evidence is weak

Cons

Free Spotter includes the Quick Debrief only; PDF Engineering Reports and Crew Rooms require paid access
Needs a long enough session with clean flying laps
iRacing session files only — not a live overlay

Setup Instructions

In iRacing: Options → Drive → tick Auto-record telemetry → Save. Drive a session of about 10 laps (around 8 clean flying laps; out-laps and off-pace laps are not counted). Open File Explorer → Documents\iRacing\telemetry\ and pick the most recent ibt file (named with car, track, and date). Files under about 500 KB are too short. Go to pitdelta.co, choose Just me, Me + a faster driver, or Me + my crew, then drop the file. Verify your email with a one-time code (no password). Processing usually takes under 90 seconds. Open the Quick Debrief in the browser or download the PDF Engineering Report. Apply one assignment next stint.

Requirements: iRacing Auto-record telemetry enabled. A session long enough for clean flying laps (about 10 laps; files under ~500 KB are rejected). Same car, track, and layout for benchmark or crew comparisons.

Tip: Enable Auto-record telemetry once, then upload the most recent session file after a proper run. Fix only the first assignment next session — one habit often shows up in several corners.
