From live timing to a race decision

Follow the field. Put every stop in context.

Keep the race picture and the detail within reach. A collector captures iRacing on the simulator PC; the desktop viewer turns that session into separate windows for timing, traffic, strategy and analysis.

  1. Connect your session

    Run the collector on the Windows PC running iRacing. Connect the viewer on that PC or another computer on the local network, then choose the event and session.

    Explore this step

  2. Build your race view

    Choose a window profile, focus a car and select the drivers you want to follow. Open Timing, Relative and a map to connect class position with traffic on the road.

    Explore this step

  3. Investigate the next decision

    Check pit activity and the estimated pit window before considering a stop. Use race traces, lap comparisons and tables to understand the pace behind the position.

    Explore this step

The current product uses Windows desktop apps. The collector stores session history locally; the viewer can connect on the same PC or across the local network.

What to look for

Separate blocks show each class with its own order, GAP and INT. Class colours and best-sector highlights make the different battles easier to follow. A class leader can still have traffic from other classes nearby on the road.

Make it your own

Enable Split by class in Timing and use the class selector to narrow the field. Keep Relative or the track map beside it to distinguish class competition from physical traffic.

What to look for

The relative view wraps positions around the lap. Positive values are ahead and negative values behind. The seconds are estimates based on pace and the track's time profile, not the same measurement as the timing tower's race gap.

Make it your own

Focus the car you want to follow, choose driver or team names and set how many cars to show on either side. Read it with the map when preparing for traffic or a rejoin.

What to look for

The speed curves are derived from captured distance and time, then smoothed; they are not private pedal or steering telemetry from rivals. Delta is cumulative: positive loses, negative gains. A running lap ends where the captured car has reached.

Make it your own

Choose the reference car and its last, best or current lap, then select the cars to compare. Inspect the speed and delta at the same distance and check the sector table as each sector completes.

Pit window & rejoin — Test what a stop could mean for position within the focused car's class. Pit strategyEnlarge screenshot

What to look for

The pit window combines typical moving loss and stationary time, using measured stops, circuit history or a default. Rejoin estimates the neighbours after a stop now. Net equalizes observed stop counts within the class; it does not know every rival's fuel plan.

Make it your own

Choose the class, inspect the automatic window's source or enter and lock a manual loss. Compare the projected position and margins with actual pit activity. A free-stop marker depends on that assumed loss and the current gaps.

06Return to a session

Use Control to select the data source, event and session. The collector keeps local timing, stop, message and weather history; detailed recent traces have a different retention from that stored history.

Understand the data

Know what is measured and what is projected.

Pitwall connects the information available from iRacing with calculated timing and strategy views. A useful decision still depends on the right class, reference and assumptions.

Timing and nearby traffic differ

Race gaps use captured passage times at the same race-distance point. Relative seconds estimate travel between nearby cars from pace and a track profile. Lap-compare speeds are derived and smoothed from distance and time.

A pit window is an assumption with evidence

Automatic loss estimates use available race stops, circuit history or a default; you can lock a manual value. Net compares stop counts and rejoin adds the assumed loss to current gaps. Neither reveals rivals' fuel loads nor guarantees their future strategy.

Tyre knowledge has limits

Compounds and stints come from captured session data. A rival staying on the same compound does not reveal whether a new set was fitted. Fresh-set information must remain unknown where the available data cannot establish it.

Coverage and class context matter

Official lap times are used where available; sectors and microsectors are calculated from captured samples. Missing data can leave incomplete sections. Class comparisons, current conditions and the chosen reference must stay visible when reviewing results.

Good to know

Do the collector and viewer need to run on the same PC?

No. The collector runs on the Windows simulator PC, while the desktop viewer can connect on that machine or another computer on the local network.

Can I review a session after the live capture?

The collector stores session history locally, including laps, stops, messages and weather. Select the stored event and session in the viewer. Detailed distance traces cover recent captured running and are not equivalent to unlimited archived telemetry.

Does Pitwall know rivals' fuel loads or every tyre change?

No. Pit-window and Net calculations use observed stops and timing assumptions. A rival's fresh tyre set is generally unknown unless the available data, such as a compound change, establishes it.

Does Net predict the final classification?

No. It shows a virtual class order after equalizing observed stop counts using the chosen pit loss. Future pace, traffic, further stops and changing conditions can alter the outcome.

Can I share the analysis?

Save a view as PNG with the camera button, which also copies it to the clipboard. Data tables can export the visible tab to CSV for review outside the application.
