MPC555 ECU Technical Specifications and Potential
The MPC555 is a flexible engine control unit produced by Magneti Marelli and TRW with a very wide application range. This ECU is used in both small 1.3L-1.4L Fiat Group passenger cars and large 7.2L-12L commercial truck diesel engines. It appears in very different segments such as Alfa Romeo (Mito), Fiat (Linea, Punto Evo), Lancia (Musa), Renault Trucks (Magnum), and Volvo (FE). It manages MultiAir electro-hydraulic valve system and Multijet Common Rail technologies. 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:
- MultiAir electro-hydraulic valve system optimization
- Multijet Common Rail injection optimization
- Safe increase of turbo boost pressure
- Very wide engine capacity range (1.3L-12L)
- Passenger car and commercial truck dual-segment management
- Fiat Group platform compatible settings
- Renault/Volvo commercial truck optimization
- Multi-brand and multi-segment balance

Why Customized Chip Tuning?
Factory software is left conservative considering emission standards and multi-segment priority. OnlineChipTuning shapes the file you read from your vehicle according to your requests.
Advantages of our customized service:
- Optimizes MultiAir turbo performance in Alfa Romeo Mito.
- Strengthens MultiAir petrol dynamics in Fiat Punto Evo.
- Preserves Multijet diesel efficiency balance in Fiat Linea/Lancia Musa.
- Increases commercial truck power and load capacity in Renault Magnum/Volvo FE.
- Balances fuel consumption through more efficient combustion.
- Preserves multi-segment quality character.
MPC555 Stage 1 and Stage 2 Differences
Power achieved only through software without any part replacement on the vehicle. Emission systems remain in original condition. Safe performance increase is targeted without shortening engine life.
- Safe & Stable Power/Torque Increase (+20-60 HP)
- MultiAir/Multijet System Optimization
- Sharper Throttle Response
- Segment-Specific Efficiency Protected
Specific to vehicles with modifications such as DPF Delete (diesel), EGR Off, and/or performance exhaust system. Maximum torque is unlocked by freeing the engine from all restrictions.
- DPF / FAP Completely Off (Diesel)
- EGR Valve Deleted
- Maximum Torque and Horsepower (+40-120 HP)
- Alfa/Truck High Performance
