FAQ
1.How does a turbocharger increase engine power?
It compresses more air into cylinders using exhaust gases, improving combustion efficiency for 30-50% more power.
2.Do I need to upgrade other parts when installing an aftermarket turbo?
Yes, often requires upgraded fuel injectors, ECU tuning, and high-flow air filters to prevent lean mixture or knocking.
3.How does ECU tuning affect turbocharged engines?
Optimizes boost pressure/fuel delivery, but requires compatible hardware (e.g., cooling system).
4.OEM vs Aftermarket ECU differences?
OEM ECUs prioritize reliability/emissions, while aftermarket ones focus on performance.
5.What does a high-pressure fuel pump do?
Increases fuel pressure for better atomization, critical in direct injection engines (200+ bar).
6.How to test a solenoid valve?
Use a multimeter to check resistance (typically 10-20Ω), or listen for "click" when powered.
