Tune-Up Connect

Tune-Up Connect turns your phone into the display and the logger for your car. It connects to two things at once: the ECU in your BMW, over a Wi-Fi OBD adapter or a wired ENET cable, and a GPS timing box over Bluetooth. You get live boost, air fuel ratio, ignition timing and temperatures at the rate your ECU can actually answer, and accurate speed from a 10 Hz GPS receiver at the same time. WHAT YOU CAN DO Live gauges. Pick the channels you care about and lay them out the way you want. Boost is drawn against the ECU's own boost target, so the gap opens up in front of you the moment something is off. Speed runs. 0 to 100 km/h, 0 to 60 mph, quarter mile, roll ons, braking distances. Timing comes from Doppler ground speed rather than from position differences, and every result carries the speed accuracy it was measured at, so you know whether to trust it. Combined logging.
