Race Engineer follows your race and tells you what you need to know: how much fuel to add, when to stop, and whether your fuel lasts to the end.
Every lap it works out again how much fuel you need to finish, based on what you're burning. Saving fuel, traffic or a longer stint all show up in the number. If the fuel gauge gives a strange reading, it notices instead of trusting it.
How the fuel calculator works →In Automatic Mode, Race Engineer sets exactly how much fuel to add at your next stop, so you don't do the math at 300 km/h. It only adjusts the fuel amount, and only during a pit stop.
How Auto Pit works →
Built from the fuel you actually burn and the race distance left: the earliest lap you can stop, the latest safe lap, and the call when it is time. In a timed race, your lap time sets how many laps are left.
How the pit window works →Race Engineer speaks up about what iRacing doesn't show you: the track has been declared wet, you're missing your fuel-save target, or you could ask for less fuel at the next stop if you save the rest on track.
How race alerts work →
Race Engineer compares the time a fresh set of tires would save against the extra pit time changing them costs, corner by corner. It recommends a change once there is recorded history for this car and track. With no data yet, it tells you so.
How tire strategy works →Lap times, fuel used, pit stops and cautions are saved for each car and track. You can open an old race and see how the strategy played out. Everything stays on your computer, with no account.
The whole app (dashboard, history, alerts and the spoken voice) is available in English, Portuguese and Spanish, and you can switch languages from settings without restarting. The same page is where you choose how much the engineer speaks: everything, only the short calls, or nothing.
Pick which alerts go to your iRacing chat and write the text your way. Race Engineer saves the macros into iRacing for you and only touches the ones you edit.
When a new version is out, the app lets you know. You update with one click whenever you're not connected to iRacing, and if the new version doesn't start, it goes back to the previous one.
