I have a Mychron EVO-3 with an Mychron 3 dash. It’s similar to a Mychron 3 Gold. The E-Box has inputs for two temp sensors plus beacon, display, speed and RPM. Internal battery in the E-Box. Have the sensors and cables for the IR beacon and CHT. Track mapping can be done as the E-Box has two accelerometers. If interested, I’ll get you a price.
