PLX Kiwi Wi-Fi with Rev by Dev Toaster
This is technically a bundling of two products. The first bit is the PLX Kiwi Wi-Fi, a Wi-Fi dongle that connects to your vehicle's onboard diagnostics port and broadcasts vehicle data to a paired iPhone. The second part is the Rev app by Dev Toaster, which displays the data in an easy-to-understand format, along with GPS lap times for track use.
