Your race engineer for iRacing.

It keeps track of your fuel during the race, tells you when to box, and can set the right amount of fuel in iRacing's pit menu for you.

Free. No account. Independent third-party app, not affiliated with iRacing.

Race Engineer's Fuel page during a race: the recommendation reads STAY OUT with its reason, a chart traces fuel lap by lap from the start through the pit stop to the projected figure at the flag, and the engineer's radio and per-corner tire wear sit underneath.

In the car

It sets your fuel in the pit menu.

Recorded in an iRacing session

On the left, Race Engineer's call: box this lap, add 6.8 L. On the right, iRacing's pit menu already set to 7.0 L. You didn't touch anything.

The call is also spoken, in English, Portuguese or Spanish.

Recorded in test mode, which simulates the end of a race so you can try it in practice. The fuel goes into the car as usual. How to try it yourself →

In the pit box

Then just pull into your box.

You stop in your box and iRacing adds what was set: the tank goes from 38.1 L to 43.3 L, without you opening the pit menu.

Pit entry to fuel delivered
Fuel

How much fuel you need, lap by lap.

Every lap it works out how much fuel you need to finish and how many stops that takes, based on what you're actually burning.

Pit strategy

When to stop.

It tells you when you can already stop and the last lap you still can.

iRacing data

Uses iRacing's official data.

It reads iRacing's own telemetry, and only sends the chat messages you chose.

In a short race, iRacing's own fuel calculator is enough. Race Engineer makes the difference in long races, when there's a safety car, when you need to save fuel, or when the race ends up longer than you expected.

Race Engineer's History page: past races for one car and track, the recorded fuel curve for the selected session, and its pit stops with fuel delivered and time in the pit lane.
