MEVD17.2.6 ECU: Professional Chip Tuning File Service for BMW N55 Engines
The key to unlocking performance in BMW's powerful N55B30 turbocharged gasoline engine series (335i, 740i, X3 35i, etc.) and Alpina's N52B30 engine is the MEVD17.2.6 ECU developed by Bosch. This advanced engine control unit precisely manages TwinPower Turbo technology, the Valvetronic system, and direct injection.
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, Intake, etc.). By analyzing the complex torque limiters, boost control, and ignition maps of the MEVD17.2.6 ECU, we ensure you get maximum power within the engine's safe limits.
This page details the technical capacity of the MEVD17.2.6 ECU, supported BMW E and F Series models, and the Stage 1 and Stage 2 advantages you'll gain by submitting files through OnlineChipTuning.com.
MEVD17.2.6 ECU Technical Specifications and Potential
The MEVD17.2.6 is a brain with a TriCore processor that processes all thermal and mechanical data of direct injection and turbocharged gasoline engines thousands of times per second. The original file you upload to our platform is processed with professional software like WinOLS and ECM Titanium 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
- Making Ignition Timing maps compatible with fuel octane
- Sharpening of Throttle Response
- Expansion of torque limiter maps
- Optimization of VANOS (Variable Camshaft) timing
Which BMW Models Feature MEVD17.2.6?
This ECU is common in 3.0 liter turbocharged gasoline engines of BMW E and F chassis produced especially between 2010-2015. The most processed models in the OnlineChipTuning file panel are:
- Alpina B4 (F32) 3.0L TT N52B30 Petrol
- BMW 3-Series (E90) 335i N55B30 Petrol
- BMW 3-Series GT (F34) 335i N55B30 Petrol
- BMW 7-Series (F01) 740i N55B30 Petrol
- BMW X3-Series (F25) 35i xDrive N55B30 Petrol
- BMW X4-Series (F26) 35i xDrive N55B30 Petrol
In these vehicles, the MEVD17.2.6 can offer incredible power increases with software (Stage 1 with +50/70 HP, Stage 2 with +80/100 HP), especially when combined with hardware upgrades like downpipe and intercooler. The N55 engine's single turbo structure provides a very wide power band with proper software.
Why Customized Chip Tuning?
Factory software is left very conservative considering all types of fuel quality (91-98 octane range), harsh climate conditions, and long engine life. OnlineChipTuning shapes the file you read from your vehicle according to your requests (for example: "I use 98 octane fuel", "Downpipe installed", "I want Pop&Bang", "No check engine light").
Advantages of our customized service:
- Provides a more elastic power band by minimizing turbo lag at low RPMs.
- Removes Vmax (250km/h) speed limiter.
- Optimizes fuel consumption through more efficient combustion (in calm driving).
- Perfects the harmony between automatic transmission and engine torque.
- Fully utilizes the single turbo potential of the N55.
- Enables performance-oriented operation of the VANOS system.
MEVD17.2.6 Stage 1 and Stage 2 Differences
Power achieved only through software without any part replacement on the vehicle. Original exhaust and intake systems are preserved. Safe performance increase is targeted without shortening engine life.
- Safe & Stable Power Increase (+50-70 HP)
- Turbo Lag Reduction
- More Responsive Throttle
- Compatible with Original Parts
Specific to vehicles with modifications such as Downpipe (Catalytic Converter Delete), performance intercooler, and/or cold air intake. Higher pressures are unlocked by allowing the engine to breathe comfortably.
- Pops & Bangs (Exhaust Crackles)
- Cat Off / O2 Sensor Delete
- Maximum Torque and Horsepower (+80-100 HP)
- Synchronized with Performance Hardware
Special Solutions Offered with OnlineChipTuning
Since MEVD17.2.6 ECU is a gasoline unit, there is no DPF or AdBlue; however, we have gasoline vehicle-specific performance and comfort solutions:
- VMAX OFF: Removal of factory speed limiter (250km/h).
- CAT / Lambda Delete: Turning off the check engine light (CEL) that comes on after downpipe installation and blocking O2 sensor errors.
- Pops & Bangs (Burbles): Exhaust popping sounds when lifting off the throttle (Optional, Stage 2 recommended).
- Cold Start Noise Reduction: Reduction of high idle noise during cold start.
- Sport Display Calibration: Updating Sport Indicators (HP/NM) on the iDrive screen according to new power.
- Start/Stop Delete: Permanent deactivation of the system.
- Launch Control Activation: Enabling race start feature (on compatible models).
- Rev Limiter Adjustment: Adjustment of RPM limit (within safe boundaries).
- Flat Foot Shift (FFS): Gear changes without lifting off the throttle (manual transmission).
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, identify the engine version (N55B30, N52B30), learn the fuel octane you use, add the features you want (e.g., Stage 2 + Pop&Bang + Cat Off + Vmax Off) and send the file back to you.
Why Us?
- 24/7 File Service: Fast turnaround time so you don't keep your customer waiting (average 2-4 hours).
- Technical Support: You can get support for problems during file reading, writing, and vehicle adaptation stages.
- Warranty: Our software is prepared within engine protection limits (Component Protection).
- Gasoline Engine Expertise: We have experience in precise ignition and boost control of N55 engine.
- Octane-Based Optimization: Custom maps according to your fuel quality.
