Intro
Important things to know before starting your DRE journey
Become familiar
For built-in simulator commands, set and save the binding in the simulator. DRE sends it when requested by voice or an optional controller input. Your physical keyboard remains handled directly by the simulator. Check the read-only binding in DRE → Controls → Sim. Controls guide.
Become familiar
DRE usually waits to speak until you are less busy, such as on straights or off throttle.
Become familiar
For iRacing, set Max Cars to 63. Lower values can cause wrong positions or timing due to missing car data.

About gaps
About gaps
The term gap has different meanings in practices and quals versus in races
Practice & Qualification
In practice and qual, “gap” refers to the differences in fastest lap times set between your car and the other. Eg. If you did a lap time of 1:22 and the other car did a 1:23, DRE would give a feedback like “gap to car behind is 1 second”.
Race
In races, “gap” refers to the interval time between your position on the track and that of the other car. So if you eg. are halfway through the lap (50% lap distance) of 1:22, you would be at 41 seconds into the lap (simplified calculation here). The other car would be eg. at 40% distance, so that would be around 33 seconds into the lap. The gap would then be 41 – 33 seconds = 8 seconds. DRE would report this as “Gap to car behind is 8 seconds”.
It is therefore only possible to compare the “gap” to the Relative Tab in races, where the gap should reflect the Relative Tab Timing data. In practice and qual sessions, the “gap” refers to the differences in lap times.
Alerts
Alerts in DRE are verbal, spoken messages, informing you about just about everything!
They automatically start monitoring the simulator action for various events, warnings, proximity alerts, etc. You can select which alerts to hear using the settings of the DRE app.
See the DRE in-app tips for more about alerts.


Signals
![]()
Signals are non-verbal sounds playing that indicate rich information. Let’s break that down.
- Non-verbal: DRE will not speak any information using voice but rather rely on sounds to relay information
- Rich information: The sounds produced are dynamic and can indicate changes, improvements, and performances.
Signals take time to acclimatize and to learn. Please spend some time with each and learn its traits. One example is the Delta Wave Signal. This indicates your performance on track by comparing the current driving to eg. your previous lap time or another driver’s position on track. The sound signal has information about whether you’re gaining or losing time, how fast the change is happening, etc..
See the DRE in-app tips for more about Signals.
