Not long ago, those who couldn’t afford forged pistons and conrods, a bigger turbo, or other performance upgrades would opt for ‘chipping’ their rides to gain more power. In most cases, this process involved swapping the car’s factory Electronic Control Unit (ECU) with an aftermarket one programmed to boost overall performance.
Nowadays, this wizardry has evolved, and rather than swapping the ECU, tuners can remap the factory chip without any physical alterations to your car.
They just plug a laptop into the vehicle’s onboard diagnostic port (OBD) and overwrite the manufacturer’s software with a custom one, enabling the engine to produce more power.
