This app works with the Auto-Rel OB2 Relay, from Fast Lane Innovations LLC, for use in automobiles. Do you have an automotive accessory you want to control based on throttle position, speed, coolant temperature, etc? Use this app to program the Auto-Rel relay to react to one or more of a range of OBD2 parameters, so you can select the parameter and range of values for the relay to be activated.
