Included features
Alongside the power stage, toggles you control from the app. For track / closed-road use; road legality is the user's responsibility.
Crackle / Pops (adjustable)
Controlled crackle and pops from the exhaust. Rev range, speed and intensity are set from the app — without risking engine health.
Cold Start Delete
Silences the high-idle, noisy warm-up on cold starts. Quiet mornings — fully off or off once warm.
Speed Limiter Off
Removes the factory electronic speed limit (Vmax).
RPM Limiter
Adjusts the rev limit to suit your stage.
OPF / DP Calibration
Compatible calibration for particulate-filter delete or downpipe cars.
Sport Cooling
Earlier, more aggressive cooling for high load and track use.
What is included?
MOSTUNED Flasher (€350) + 280/300 HP package (€500) together: €750 instead of €850.
Two power stages: 280 HP and 300 HP. Both run on stock hardware, software only — no downpipe or parts required.
With the Flasher you also write your own file (custom map): a .bin or .mos from your own tuner goes in with the same app.
Already own the Flasher? Then buy only the 280/300 package for €500 — here.
A full backup of the original software is taken; you can return to stock at any time.
Requirements
Turkish-market 1.6 B48B16 (MG1CS003 ECU) models — 320i (G20), 420i (G22/G26), 520i (G30), X3 sDrive20i (G01). Post-June-2020 cars need the ECU unlocked — the app checks for free; if locked, we do the unlock.
iPhone + ENET/WiFi-ENET adapter. Full output comes on a well-maintained car.
FAQ
Do I want 320 too?
This package includes 280 and 300 HP. For 320, buy the Full package (€900) upfront or add the 320 HP add-on (€200) later.
I already own the Flasher — what do I pay?
Only the 280/300 package: €500. Choose "I own the Flasher" on the Find my package page and the right price appears.
Can I write my own file?
Yes, the Flasher is part of this package; custom map writing is enabled.
Refunds?
No refunds once the calibration is delivered; see the terms of use.
