MEVD17.2.4 ECU: Professional Chip Tuning File Service for BMW N20 Engines
The key to unlocking performance in BMW's legendary N20B20 engine series (320i, 520i, etc.) is the MEVD17.2.4 ECU developed by Bosch. This advanced engine control unit manages TwinPower Turbo technology and the Valvetronic system.
As OnlineChipTuning, instead of standard database files circulating on the internet, we offer custom file services prepared from scratch by our engineers according to the vehicle's current mechanical condition, fuel quality, and installed hardware (Downpipe, Intercooler, etc.). By analyzing the complex torque architecture of the MEVD17.2.4 ECU, we ensure you get maximum power within the engine's safe limits.
This page details the technical capacity of the MEVD17.2.4 ECU, supported BMW F Series models, and the Stage 1 and Stage 2 advantages you'll gain by submitting files through OnlineChipTuning.com.
MEVD17.2.4 ECU Technical Specifications and Potential
The MEVD17.2.4 is a brain with a TriCore processor that processes all thermal and mechanical data of direct injection and turbo-fed engines thousands of times per second. The original file you upload to our platform is processed with professional software like WinOLS to reveal this ECU's hidden potential.
Main optimizations we offer on this ECU:
- Performance-oriented adjustment of Air/Fuel (AFR) mixture
- Stable increase of Turbo Boost Pressure
- Ignition advance maps made compatible with fuel octane
- Improvement of Throttle Response
Which BMW Models Feature MEVD17.2.4?
This ECU is common in 1.6 and 2.0 liter turbo gasoline engines of BMW F chassis produced especially after 2011. The most processed models in the OnlineChipTuning file panel are:
- BMW 1 Series (F20) 116i / 118i / 125i
- BMW 3 Series (F30) 320i ED / 328i
- BMW 5 Series (F10) 520i / 528i
- BMW 4 Series (F32/F36) 420i / 428i
- BMW X1 (E84) and X3 (F25) sDrive/xDrive 20i - 28i
- BMW Z4 (E89) sDrive 18i / 20i / 28i
In these vehicles, the MEVD17.2.4 can offer incredible power increases with software (Stage 1 with +40/50 HP), especially in "detuned" versions (for example, 320i ED).
Why Customized Chip Tuning?
Factory software is left very tolerant considering all types of fuel quality and harsh climate conditions. OnlineChipTuning shapes the file you read from your vehicle according to your requests (for example: "No check engine light", "Exhaust pops", "Limiter delete").
Advantages of our customized service:
- Provides a more aggressive driving experience by eliminating sluggishness at low RPMs.
- Removes Vmax (190km/h or 250km/h) speed limiters.
- Reduces fuel consumption (in calm driving) by providing more efficient combustion.
- Perfects the harmony between transmission and engine torque.
MEVD17.2.4 Stage 1 and Stage 2 Differences
Power achieved only through software without any part replacement on the vehicle. Safe performance increase is targeted without shortening engine life.
- Safe & Stable Power Increase
- Turbo Lag Reduction
- More Responsive Throttle
Specific to vehicles with modifications such as Downpipe (Catalytic Converter Delete) and Sport Air Filter. Higher pressures are unlocked by allowing the engine to breathe comfortably.
- Pops & Bangs (Exhaust Crackles)
- Cat Off / O2 Sensor Delete
- Maximum Torque and Horsepower
Special Solutions Offered with OnlineChipTuning
Since MEVD17.2.4 ECU is a gasoline unit, there is no DPF or AdBlue; however, we have catalytic converter and sensor solutions that replace these and are frequently requested:
- VMAX OFF: Removal of factory speed limiter.
- CAT / Lambda Delete: Turning off the check engine light (CEL) that comes on after downpipe installation.
- Pops & Bangs (Burbles): Exhaust popping sounds when lifting off the throttle (Optional).
- Cold Start Noise OFF: Cancellation of high idle noise during cold start.
- Sport Display Calibration: Updating Sport Indicators (HP/NM) on the vehicle screen according to new power.
- Start/Stop Delete: Permanent deactivation of the system.
Custom File Preparation Process for Your Vehicle
The process works with the "develop file" logic, not the "upload ready file" logic. You read and upload the original file to the system, our engineers verify the Checksum of the file, add the features you want (e.g., Stage 1 + Vmax Off + Pop&Bang) and send the file back to you.
Why Us?
- 24/7 File Service: Fast turnaround time so you don't keep your customer waiting.
- Technical Support: You can get support for problems during file upload or writing stages.
- Warranty: Our software is prepared within engine protection limits (Component Protection).
