Diesel box
A modern diesel engine has advanced control systems that work together to make everything work. A diesel box only manipulates the signals, the purpose of which is to increase the fuel pressure slightly, this is the only thing a diesel box does. It does this without informing the other control systems in the car.
A diesel box deceives the car's control system, as a result of which other values become incorrect. For example, the trip computer shows incorrect fuel consumption, the anti-skid system (ESP) and the automatic transmission receive incorrect values for torque, torque reduction when shifting for durability, cleaning (regeneration) of the particulate filter does not work as intended.
Exhaust gas temperature and calculation of service intervals and the diagnostic system are disrupted.
Diesel boxes that the Swedish STT Emtec emission & engine technology laboratory has tested have shown approximately 1/3 of the guaranteed power increase. Another disadvantage was exceeding the maximum exhaust gas temperature in the turbo and too high fuel pressure.
Trim chip
An updated software that replaces the car's original is installed in the car's engine control system - ECU. The software has a predetermined power increase regardless of the engine or transmission's condition and wear, mileage and area of use. A tuning chip is never an optimal solution.
Tailored optimization
Just as it sounds, an individually tailored engine software that takes into account, among other things, mileage, condition of the turbo and other engine components, and the car's area of use. TuningChip only works with tailored engine optimization.
