You can optimise these settings and upgrade your car engine to its optimal capacity and increase the performance and economy of your vehicle. You can optimise these settings by rewriting with programs in the ECU with the use of a laptop.

These programs replace the manufacturer’s installed programs and give you the ability to customise these settings to run the engine to its maximum capacity depending upon the vehicle. This process of optimising a petrol engine is called chip tuning or remapping.

To chip tune a petrol engine, you need a laptop to install the program and a vehicle’s OBD adapter plug to connect the laptop with the car’s OBD port. This process of remapping doesn’t take much time in modern vehicles, but in older vehicles, you have to replace the ECU completely with a new chip with pre-installed programs.

With the help of software on your laptop, you can easily rewrite the manufacturer’s pre-installed programs and replace them with your customisable programs. This process usually takes from 20-30 minutes. You can revert to the manufacturer’s standard programs anytime you want to.

An engine functions by igniting the mixture of air and compressed fuel inside the cylinders. Vehicles with turbochargers have more fuel compression that allows more fuel to fill in these cylinders before ignition the mixture. More fuel compression leads to more power, thus increasing the performance of the engine, making it more economical or fuel-efficient.

When you chip tune the engine, the new program mainly changes the fuel compression, fuel: air ratio and boost pressure that makes the turbochargers or superchargers increase the fuel compression. Hence vehicles without turbochargers can have a limited increase in power and speed, whereas vehicles with turbochargers can unlock the maximum capacity of the engine with proper configuration.
