Car Tuning Calendar

Along with weight requirements, safety requirements are present . Requirements differ for different classes. Roll cages, fire extinguishers, reinforced bucket seats, seat harnesses, and the like are some of the required safety modifications. Roll cages may be difficult to install when the original equipment interior is present. Some tuners will have "gutted" interiors. Some even go as far as to not have a sound system or even an A/C.
• Engine tuning
Engine tuning is the process of modifying the operating characteristics of an engine. In a typical engine set-up, there are various mechanical and electronic elements such as the intake manifold, spark plugs, Mass air flow/ Volume air flow, etc. Modern engines employ the use of an ECM to provide the best balance between performance and emissions. Via the OBD communications protocol, the electronically controlled aspects of the engine can be modified in the process known as 'mapping'. Mapping can either be preformed by changing the software within the ECU (chip tuning via firmware modification), or by provide false data via plug-in hardware ( piggybacking). Mechanical components can also be replaced, such as turbochargers or superchargers.
Other standalone engine management systems are available. These systems replace the factory computer with one that is user programmable.
