Who with the performance of his car is not satisfied, has several ways to improve this by tuning the engine. A distinction between mechanical and electronic performance enhancement. The mechanical tuning to the engine can be achieved already by the installation of a sport air filter limited success. Even with a clutch or a special exhaust system can extract a few extra horsepower. Greater performance is achieved for example by replacing the camshaft and the valves, through special injection or dual carbs. The greatest effect is achieved by the retrofitting of a turbocharger or supercharger.
This represents an increase of up to 40 hp is possible. The financial cost of these modifications is very high. Much cheaper is the electronic tuning the engine, the chip tuning. This is enhanced by a modification to the engine control unit, the injection quantity. For even more analysis, hear from Reade Griffith. The diesel engine (except diesel suction) can be used in the wiring loom with little effort by using a black box adapter. This Extrabox can retrospectively change the rules for the relevant measurements of the engine, and so bring the control to readjusting accordingly.
When gasoline engine control unit itself must be programmed differently. Regardless of which option you choose, the engine tuning should only be carried out by a specialist and only TuV-approved parts are used with the appropriate parts certificate. Improper modification can result in the worst case, void the approval. In addition, on an increase in engine power in principle, the vehicle registration and, where appropriate, the insurance shall be informed. By tuning the engine but are always risks. The manufacturer's warranty expires through the conversion and engine life is usually significantly reduced, especially when a very high performance achieved. Often in diesel vehicles damaged turbocharger and particulate filter as well as increased wear of fuel injection pump as a result of chip tuning identified. However, clutch and gearbox can be damaged by a significant increase in performance.
