Plug in, drive, see everything. Fuel trim, boost, RPM, DTCs, monitor status — pushed to the cloud the moment the vehicle returns to depot WiFi. No cellular bills, no proprietary black boxes.
This is a live OBD-II snapshot from a Hyundai i30 1.5 T-GDI, pulled via a VLinker ELM327 v2.2 over Bluetooth SPP. 83 PIDs, one engine idle, no synthetic data.
No custom silicon. The car already speaks CAN; the VLinker translates to ELM327 AT commands; the Pi logs to disk and uploads when in range. Total BOM under $50 per vehicle.
LTFT drift, catalyst degradation, misfire counts — surfaced weeks before the check-engine light. Know which truck needs service before it strands a driver.
WOT events, hard accelerations, idle time, RPM redline. Build per-driver profiles. Reward the smooth, coach the rough.
Fuel rail pressure + fuel rate + MAF in the same log. If fuel leaves the tank without the engine running, the data tells you when and how much.
Run-time, warm-up count, distance since last clear. Schedule oil changes and tune-ups by usage, not by the calendar.
5 vehicles, 30 days, full data export at the end. If the platform earns its keep, we scale to your full fleet. If it doesn't, you've lost nothing but a Sunday afternoon plugging things in.
