Should You Modify Or Optimise?

Modify or Optimise – Choose wisely.

Should you modify or optimise? How do you get the most performance from your engine? Most people think that you have to modify your engine to achieve performance. The act of modification usually requires the disassembling, changing or replacing of a mechanical part to improve power output. These hardware changes may include work such as porting and gas-flowing the cylinder head and manifolds. In addition, you may need to replace certain devices. These include fuel injectors, carburetors, fitting larger turbochargers, and installing different exhaust systems or camshafts. Moreover, you may even want to increase the engine size and compression ratio. The question remains, should we modify or optimise? In previous articles, we touched on the issue regarding tuning and sensible optimisation. It is important to understand that senseless modification can cost you dearly.

The downsides of modification

First of all, a vehicle under factory warranty becomes null and void because the vehicle is no longer standard. The second disadvantage is that you unbalance the apple cart; when you improve (modify) one thing, another suffers. It is true, engine modifications may improve power and performance. The downside is that this usually comes at the expense of fuel economy and the life expectancy of the engine. This may explain why manufacturers are unwilling to foot the bill if something goes wrong with your modified wheels. Devious workshops “tune” engines to within an inch of their lives. When there is an inevitable engine failure, it is your pocket that is hurt.

Can you optimise your car safely?

However, this does not mean that there is nothing you can do to improve your car’s power and efficiency. Modify or optimise? The moment Unichip comes into the picture, things change drastically. We don’t believe in modifying people’s cars to the detriment of reliability and fuel consumption. The Unichip piggyback computer is added to your engine’s existing electronic control unit (ECU). It optimises its signals to make your engine work better without changing the design or any of the engine’s hardware. Contrary to popular belief, the standard settings programmed into the ECU do not do an optimal job. This is because they have to cater to many manufacturing variations of individual engines, different fuels, altitudes, and other variables. The inevitable compromise that this situation creates, almost always leaves room for improvement.

Specialist technicians program the Unichip to take all the characteristics and peculiarities of your engine into account. They divide these settings into several map sets. For example, your engine will have an “economy” map for part-throttle and “power” map for full-throttle driving. This will ensure that you have the best possible economy when driving around town. It will also ensure that you have the maximum power available when overtaking. Other map sets are also available. The Unichip offers you an anti-theft option. During this setting, the Unichip renders your car’s engine out of action. There is also a towing/4×4 setting. The best of all is that there is no compromise and no negative effect on your engine’s durability. Does this answer your question about whether to modify or optimise? This is the primary reason why we at Unichip don’t modify engines. At Unichip, we tune and optimise them.
