Stage 1 Remap
Balanced power and torque on standard hardware. No parts required. Read more
BMW remapping — no workshop visit,
verified with real datalogs.
A car's real potential does not come from an off-the-shelf file. It comes from engineering that is checked against measured data. We build the calibration; you write it yourself, from your phone.
- ✓ Knock protection preserved
- ✓ Original file backed up
- ✓ Delivered with a datalog
- ✓ Return to stock any time

Remote flashing — authorisation is bound to your VIN
No workshop booking, no shipping, no ECU removal. Encryption keys never reach the phone; the calibration is signed on our server.
- 1 Send your VIN and vehicle details, and choose your package.
- 2 Your chassis is authorised on our system.
- 3 Open the MOSTUNED app and connect to the car with an ENET or WiFi-ENET adapter.
- 4 The app reads the VIN, downloads the calibration signed for it, and writes it.
You need an iPhone plus a USB-C to Ethernet or WiFi-ENET adapter. Verified coverage: the Turkish-market G20 320i — B48B16 (1,597 cc) engine, MG1CS003 ECU. Coverage is expanding and will be announced here; ask anyway if your car is not listed. Prerequisite: BMWs built after June 2020 need the ECU to have been unlocked beforehand. The app checks this for free the moment it connects — see DME unlock.

Our approach — engineering, not a file shop
We are not in the business of selling one file to everyone. The calibration is proven against your car's own data.
Safety first
Knock detection and protection limits stay in place. We do not trade engine life for a headline figure, and we do not promise numbers we cannot stand behind.
Always a backup
The full original calibration is read out and stored before anything is written. Returning to stock is always available — you will usually want it before a service visit.
The whole chain
Air, fuel, torque and ignition are aligned together. Inflating one table does not make power; it just makes risk.
Frequently asked questions
Is BMW remapping safe?
Done properly, yes. Knock protection and safety limits are preserved, every delivery is verified on a road datalog, and the original file is backed up. What creates risk is not remapping itself, but a remap that ignores the limits.
Do I have to visit a workshop?
No. The service is fully remote: we prepare the calibration, and you write it to your own car using the MOSTUNED app and an ENET or WiFi-ENET adapter.
Can I go back to stock?
Yes. Your original calibration is backed up, and you can restore it from the app whenever you want.
What is the difference between Stage 1 and Stage 2?
Stage 1 runs on standard hardware and needs no parts. Stage 2 is calibrated around modifications such as a downpipe, intake or intercooler. Without that hardware, Stage 2 does not give you more power — it gives you problems.
Which BMW models are supported?
Currently the MG1CS003 ECU and B48 engine (G20 chassis). Coverage is growing, so ask on WhatsApp if your car is not listed.
Will this affect my warranty?
Changing ECU software can affect a manufacturer warranty — this is true of all remapping. You can return to stock before a service visit, but the write operation may leave traces in the vehicle. See our disclaimer for the details.
How long does it take?
For standard Stage packages, authorisation is usually completed the same day. Custom calibration takes longer because it runs over several datalog sessions.
