Learning
- If MDP learning is not properly performed, engine vibration and injection could be occurred.
- MDP learning should be performed after replacing ECU, reprogramming and replacing injector.
D. Injector characteristic curve for rail pressure
The fuel injection curve is also called injection characteristic curve as shown above. The amount of
injected fuel is proportional to the square root of injection period and rail pressure.
