The hidden software logic governing your car's horsepower

ECU Chip Tune - How To Increase Horsepower · 5:06 · Video: Engineering Explained · Watch at the source

In short: Most drivers view their car as a mechanical beast, but it is actually governed by complex code. This video explains how re-flashing an engine's ECU can unlock latent power by altering specific internal parameters.

An ECU chip tune, also known as an engine reflash, involves modifying the software that manages a vehicle's engine performance. By adjusting specific data points within the computer, tuners can optimize how the car operates to produce more horsepower.

The video serves as the first installment in a series exploring different methods of increasing speed through electronics rather than just mechanical parts.
