Analysis of engine modification

Enhance the dynamic performance is  obd2 the most effective way is the modification of the engine system, the first is a modification of the computer. Existing vehicles increasingly sophisticated, such as the speed limit, the speed limit, the ignition timing, the air-fuel ratio adjustment and so by the trip computer to execute, commonly referred to as the modified computer control chip to be replaced by means of different set the vehicle's performance has improved. To change the computer to the original speed and speed limit be lifted, but Be careful when using the.

Long-term in a high-speed engine, a very serious impact on the internal mechanical wear and tear, if the speed restrictions were lifted in the behind to enjoy the thrill of high-speed brings, is accelerated to reduce the service life of the engine. As for the lifting of the restrictions of the original security speed, from a security point of view, we do not agree. Because each car factory, the factory will be based on the performance and structure of the vehicle itself, the speed on certain restrictions, safety first is the move of the main considerations. If the owners of any lifting of the speed limit, when the vehicle speed to the vehicle itself critical point, some can not control, very dangerous situation.

Start from the increase in fuel, is also obtained the horsepower upgrade one of the methods, such as the recent market, a lot   Renault CAN Clip of gasoline pressure adjustment valve / SuperAFC, is to increase the air-fuel ratio of the modified goods. Booster increase the displacement to be considered to enhance horsepower, cylinder expansion or replacement of the long-stroke crankshaft can increase in engine displacement, so that the engine output naturally with c. c, the number of corresponding rise early self-Cylinder Boring increased displacement, to no longer apply, replaced by a suite facelift or construction engine sent abroad, but the universality of the vehicles on facelift cam axis much higher, generally specific tuner / European cars have only a few days before this package, like HONDA / NISSAN / BMW / M-Benz.
