Nowadays – Most Car Tuning Is Electronic

Many years ago, car engines were all mechanical.  Spark timing, valve timing, fuelling, ignition advance and mixture enrichment regimes were all controlled by mechanical devices.  It also meant that car tuning was very “hands-on” and you had to adjust or replace many of the mechanical parts if you wanted your engine to develop more power.

This could sometimes demand a lot of money and time and the compromise would not always be a happy one.

Today, all the mechanical tricks remain, but cars have acquired a barrage of electronic controllers to look after all the fine-tuning – especially so in an engine, which is controlled by an electronic control unit (ECU).

In modern, state-of-the-art engines, the ECU precisely controls the fuelling, cam and spark timing and induction manifold length, while controlling detonation within fine limits.  However, this does not mean that all cars leave the factory as finely-tuned instruments.

The reason for this is that all “identical” engines differ in their details and should ideally each have its own, dedicated ECU programming.  However, mass production precludes this, so it is up to the electronic, aftermarket car tuning industry to fill the void.

The fitment of an aftermarket, piggyback computer chip to the vehicle’s ECU can bring out the engine’s full potential and allow it to perform as it was always intended to perform.  The chip can be programmed to apply aggressive fuelling and spark timing maps at full throttle to allow the engine to produce the maximum possible power.

The “economy” map, however, would be reinstated at part-throttle, allowing the engine to run as economically as possible.

Total Car Diagnostics is the electronic car tuning performance part you have been looking for.  There are several maps available for every conceivable driving condition, even including maps to limit revolutions or turbo boost for when someone else is using your car.
