It’s finished
Mini R53 Logger — the Android app I’ve been building so I can actually see what the supercharged W11 is doing — is feature-complete, and I’m loading it onto the Google Play Store.
If you want to try it when the listing goes live (or before, if I can get you an early install), email me and I’ll sort you out.
Plug in, hit connect, and the car streams live: RPM, boost, temps, spark, knock, fuel trims, injection — the works.
What you get
Same idea as the earlier writeup, now finished:
- Live engine data fast enough for a real pull — boost, throttle, temps, per-cylinder spark, knock, MAF, injector duty, short/long fuel trim
- Wideband AFR over Bluetooth, merged into the same time-aligned CSV
- Autolog — arms on WOT, keeps the pull through gear changes, saves each run as its own file
- Live graph with channel toggles, fixed ranges, and a redline marker on the RPM trace
- Diagnostics — read and clear fault codes with R53-specific notes
- Channels & poll rate — turn off blocks you don’t care about so the ones you do watch update faster
- ECU backup / flash — read a full 512 KB backup, share it, and (carefully) write a tuner BIN back
Everything records to plain CSV and shares straight into datazap.me. Numbers were cross-checked against professional BMW diagnostic tools on a running engine.
Live graph — idle, then a pull. Toggle the channels you care about; export CSV or open datazap from the bottom.
Fast / Slow / Off per ECU block — drop what you don’t tune with and the rest gets snappier.
ECU backup and flash
Backup is read-only and safe. Write is dangerous — you need a proper checksummed BIN from your tuner, key on / engine off, and the car on a battery charger the whole time. The app does a full 512 KB backup first, then either a quick calibration write or a full 512 KB write.
Backup complete — file saved on the phone, ready to share or keep as your recovery copy.
Want to try it?
I’m putting it on the Play Store. If you want a crack at it — early install, feedback, or once the listing is up — email me:
Tell me you’re an R53 owner (or tuner) and what you want to use it for — logging, codes, backup, or the lot. I’ll reply with how to get the app.
Instagram works too if you prefer: @mattryan6729.
If you give it a weekend on the car, tell me what breaks and what’s missing — that’s how this thing got finished.
