Real circuit context
The measured line sits on Google Maps 3D so the track shape, elevation and surroundings remain visible.
Analyze iRacing IBT files
Compare your racing line, braking, throttle, steering and section times. Open Racer turns the measured differences into a focused coaching plan for your next session.
Compare the line, inputs and lap sections in one place. Leave with a focused change to test next.
See how the analyzer turns a measured Porsche 911 GT3 R session into section comparisons, driving observations and specific tests.
What the analyzer finds
See the measured difference, understand what caused it and take one clear experiment back to the next session.
From the analyzed session
The slower lap gave away 0.167 seconds through the section. Minimum speed fell to 135.6 km/h versus 142.7, then exit speed remained 2.7 km/h lower.
Hold the braking marker constant for three laps. Change only turn in timing and keep the lap with the smallest steering correction after the first apex.

Use your own session
Choose an IBT file from your iRacing telemetry folder. Open Racer reads the recorded laps and builds the racing line from the session data.
Paddock Pass is required from the first import. Payment starts only after you choose to subscribe.
Simple workflow
Enable iRacing telemetry and complete your laps as normal. The simulator writes the IBT file locally.
Open the importer and select the session you want to study. Open Racer validates the recorded channels before creating anything.
Use the 3D line and measured traces to study individual sections and define the next useful test.
Built to make you faster
The measured line sits on Google Maps 3D so the track shape, elevation and surroundings remain visible.
Speed, brake, throttle and steering are aligned by lap distance instead of shown as disconnected charts.
The report turns differences into bounded coaching instructions rather than promising theoretical gains.
iRacing saves telemetry in the Documents/iRacing/telemetry folder after telemetry recording has been enabled for the session.
Open Racer compares distance-aligned laps from your IBT file, then connects time differences to the racing line, braking, throttle, speed and steering recorded in each section. The report turns those measurements into a small number of changes to test.
Yes. The complete Porsche GT3 Algarve sample is public and can be explored without an account or Paddock Pass.
Creating a new racing line from your own IBT file requires Paddock Pass from the first import. Viewing the public sample remains free.
No. The sample keeps measured lap evidence separate from coaching interpretation and does not add independent section gains into a promised lap time.
Make the next lap count
Bring in your session and turn the racing line, inputs and section differences into a focused next test.
