Tune vs OpenBimmer

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. Record ECU channels and GPS into one session on one clock. That is what lets you see what the engine was doing at the exact moment the car was pulling. Shift beep. Set an rpm, get a single beep as you cross it, and watch the boost bar flash. Off until you turn it on. Upload. Sign in and send a recording straight to your tuning job, ready for your tuner to read. IF YOU TUNE WITH TUNE-UP Signing in pulls your jobs, your maps and every revision from Tune-Up Console. Pick the revision before you record, and the log reaches the shop already tagged with the car, the map and the revision it was made on. Comparing two revisions is then a matter of reading two logs rather than working out which log was which. When a new revision is added to your tune, the app notices and offers to record into that one instead. Everything above this section works without an account. The upload side is there for customers, not a requirement for using the app. WHAT YOU NEED A BMW with a compatible ECU, and either a Wi-Fi OBD adapter or an ENET cable to reach it. For timing, a Tune-Up Record, Dragy or RaceBox device. The app reads only. It never writes to the ECU and never changes your calibration. TRYING IT WITHOUT A CAR Open the Profile tab and switch on Demo mode. The app simulates a connected car and a connected GPS device, and every screen behaves exactly as it does on a real drive. SAFETY Start a recording before you set off, or let a passenger handle the phone. The timing features are meant for a closed course or a private road, not for public roads.

OpenBimmer turns a Bluetooth LE OBD adapter into a live dashboard, data logger and diagnostics tool. It is built for BMW turbo engines (N54, N55, B58, S55, N13, S58, S63) and works with any car that has an OBD-II port. LIVE GAUGES - Boost against target, ignition timing, intake, coolant and oil temperature, lambda and AFR, fuel rail pressure, load and more - Peak hold, min and max for every value and a shift light that follows your engine's redline - Choose what every gauge shows DATA LOGS - Record pulls with up to 34 channels - Scrub through them on a multi-channel chart - Export CSV for datazap or a spreadsheet DIAGNOSE - Read stored, pending and permanent engine fault codes with descriptions - Clear codes, check readiness monitors, read the VIN and battery voltage PERFORMANCE TIMER - 0-100 km/h, 100-200 km/h, 0-60 mph, 60-130 mph, 1/8 and 1/4 mile - GPS or OBD speed, history and best times FREE, OPEN SOURCE, PRIVATE - No account, no ads, no tracking. Your data stays on your phone. - Source code: github.com/openbimmer/openbimmer (MIT license) WHAT YOU NEED An ELM327-compatible Bluetooth LE adapter, for example Vgate iCar Pro BLE, Veepeak OBDCheck BLE, vLinker BLE or OBDLink CX. No adapter yet? The built-in demo adapter lets you try everything. OpenBimmer reads standardised OBD-II data and never writes software to your car. Never use the app while driving.
