Is There a Risk in Stage 1 Tuning for the EA888?

[JeremiahAnn]

Stage 1 tuning for the EA888, like stage 1 tuning for any other engine, carries certain risks. Here is some relevant information about the EA888: 1. Concept: The 'Volkswagen EA888 engine' is a newly designed engine by Volkswagen, integrating advanced technologies such as direct fuel injection, turbocharging, and variable valve timing, achieving a balance between power and fuel efficiency. 2. System: The fuel supply system is the most critical part of achieving direct fuel injection. To inject fuel into the high-pressure cylinders, sufficient injection pressure is required. The high-pressure fuel pump is a key component in pressurizing the fuel. The EA888 engine's fuel pump is a simple single-plunger pump, driven by a four-point cam on the intake camshaft. The four-point cam ensures synchronization between the fuel supply stroke and the corresponding injection process for each cylinder, resulting in better uniformity and repeatability of fuel injection across cylinders.
