What it's for
A dial gauge displays one ECU channel as a needle sweeping across an analog face. You can read it out of the corner of your eye while you focus on a table, which makes it ideal for channels where the rough position matters more than the exact figure: rpm, manifold pressure, coolant temperature or throttle position.
To change the channel it shows, right-click the gauge and pick a new one.
When to use it, and what to check
- Use a dial for quick at-a-glance reading. For precise values, a number display is better; for seeing what just happened, use a trace display.
- Make sure the gauge shows the channel you think it does, especially on a layout copied from another map.
- Check the units match what you're used to, so a coolant reading in Celsius isn't mistaken for Fahrenheit.
Other display options include the bar gauge and light display.
