How to Select Number of Laps in Iracing Test

Shows how to select number of laps in iRacing test for iRacing drivers — step-by-step instructions to set lap count in test sessions and fix this issue fast.

If you’re asking how to select number of laps in iRacing test, the short answer is: you set laps when you create or edit a hosted/test session — pick “Laps” as the length unit and enter the number. You’re in the right place to fix this fast; below are the plain-language steps and tips.

how to select number of laps in iracing test (Quick Answer)

When you host or edit a private test session, open the session settings and change the session length type from minutes to laps (sometimes called “Length Units” or “Length By”), then type the lap count you want and save. You cannot change lap count for official league/test sessions unless you are the host.

What’s really going on

iRacing distinguishes between session length measured by time (minutes) and by distance (laps). Official or league-run test sessions are controlled by the session host, so you can’t edit those. When you want a fixed lap count for private testing — to practice runs, pit stops, or fuel calculations — you must create or edit your own hosted session and set the length to laps.

Step-by-step fix

From the iRacing launcher, click “Create Session” or go to “My Hosted Sessions.”
Choose the session type (Test/Practice) and select the car and track you want.
Open the session settings/options (gear icon or Edit button).
Find the session length option (labelled “Length,” “Length Units,” or “Length By”) and switch from Minutes to Laps.
Enter the desired number of laps in the box that appears.
Save the session and Start/Launch it. The simulator will end the session after the lap count completes.

If you’re already inside a session and can’t change laps, exit back to the session setup screen and edit the hosted session as above. For official series or league tests you joined, ask the host to change it — you can’t override their setting.

Extra tips / checklist

Save the session as a preset if you reuse the same lap count often.
If you want realistic fuel and tyre use, set laps before launching; changing mid-session may not update fuel calculations.
If you only want single-lap hotlaps, consider Time Trial or Hotlap modes which handle lap counting differently.
If you don’t see “Laps” as an option, confirm you’re editing a hosted session (some public/series sessions lock settings).
Use the in-car lap counter and pit lane rules to practice consistent out-laps and in-laps.

FAQs

Q: Why can’t I change laps in an iRacing test I joined?
A: Because you joined a session hosted by someone else. Only the session host can change the length. Ask the host to edit it or create your own hosted session.

Q: Can I switch from Minutes to Laps mid-session?
A: No — you must end the session and edit the settings. The simulator uses the session type at start for fuel/tyre calculations.

Q: Does setting laps affect fuel and tyre simulation?
A: Yes. iRacing uses session length to calculate fuel needs and wear; set the correct lap count before you start for accurate figures.

Q: Is there a quick preset for common lap counts?
A: Yes — save your setup/session preset after you set the lap count so you can reuse it without editing each time.

Wrap-up

Set the lap count in the session creation/edit screen by changing the length unit to laps, then save and launch. If you joined someone else’s test, you’ll need the host to change it. Next step: create a short hosted test with your lap count and run a practice sequence to verify fuel and tyre numbers.
