In order for Rev to connect to your wireless OBD device, you need to select it from this list. If you have a device that is not listed here, select "Custom". You will then need to enter the IP address and port of the device by clicking on the blue circle. You will need to check the manual for your device for the IP address and port number.
In order to accurately measure acceleration, Rev needs to calibrate its measurements against the hardware in your iPhone or iPod touch. This tab will guide you through the appropriate steps.
When taking high-G turns, your iPhone or iPod touch may tilt enough that it tells Rev to change its orientation between portrait and landscape modes. You can prevent this from happening by locking the orientation. This will allow you to alter the orientation of
Rev only at the main menu.
Rev has a number of options for customizing how the gauges display. You can change them in this tab.

Make sure that you've selected the proper OBD wireless device in the Hardware tab of the Settings menu. If that still doesn't work, send an email to support@devtoaster.com
with the status of the connection indicator in the top left, along with the information about your OBD wireless device.
For iPhone users, sometimes the cell phone signal (especially in areas with weak reception) can interfere with the Wi-Fi signal being transmitted from your OBD wireless device. If you are experiencing frequent network drops, try the following. Place the iPhone into Airplane mode; this will turn off the cell hardware. Turn Wi-Fi back on, since it was turned off for Airplane mode. This should create a more stable connection to your OBD network.
Make sure that your iPhone or iPod touch is configured with a static IP address and a blank router address. To do this, go to the Wi-Fi menu in the Settings app. Click the blue circle next to the name of the wireless network provided by your OBD wireless device. Make sure that "Static" is selected. Enter the provided address in the "IP Address" field and make sure that the "Router" field is blank.
Make sure that you have properly set the mount angle (in the vehicle profile) and calibrated the axis in the global settings.
