modified by using a computer, reducing the spark advance angle at the same time closing the throttle, so that it should enter the exhaust gas mixture in the header of the combustion chamber, the exhaust blast through the header before the turbine to drive the turbine, holding certain turbine speed, and have a “touch touch …… ……” explosion.
1. When the ignition biasing action
significantly reduce the turbo lag, to maintain a certain speed of the turbine when closing the throttle, and then lift the vehicle acceleration performance.
2. Partial ignition characteristics
biasing the ignition system is originated in WRC, in order to reduce the turbo lag, and to improve the re-acceleration of the cornering vehicle deceleration.
generally used for running of the vehicle, when the vehicle is stationary refueling place, when the ignition system is biased to protect the engine and other parts of the turbine does not work, but some high-end computer can also be modified to achieve this functionality, such as using linear acceleration of the car in order to obtain maximum power output at the start, will enable the ignition system when refueling the vehicle is stationary bias to the turbine into operation quickly.
Since the mixed gas is part of an explosion in the exhaust section of the turbine in front of the head, so that a very large load on the engine exhaust valves, and a turbine exhaust header will seriously affect their life.
If the ignition advance angle adjustment to improper engine power loss, and even damage to associated components.
