 What is an Engine Control Unit:

An Engine Control Unit [ECU] is now used in modern cars instead of mechanical means to control such functions as spark timing and to regulate the air/fuel mix. The ECU is a small computer connected to many sensors around your engine. It manages the engine so efficiently that you use less fuel and your car engine meets modern emissions standards. 

Car and engine Electronic Control Unit parts dismantled:

1st Choice members offer discount prices on all used ECU units for all models, plus all the different parts [whether you need an ECU chip, sensor, computer, pins or unit]. Salvage parts from car dismantlers could help you source the replacement Car Parts and accessories you need.
