What does a flash tune do?
I was searching online for ways to boost my fuel economy, and I saw some articles about flash tuning. I don't really understand what it is – what does a flash do exactly?

Flash tuning reprograms your vehicle’s memory chip inside the engine control unit (ECU). Doing so changes how the air and fuel mixtures impact your vehicle’s performance.
Flash tuning your vehicle can provide power boosts to your engine and increase your fuel economy. However, it’s essential that if you tune your car, have it done by a highly trained professional.
A poorly done flash tune can cause:
- Higher engine temperatures
- Voided manufacturer warranty
- Damage to the fuel tank
- Damage to engine
Always hire a trusted mechanic when upgrading or modifying your vehicle to avoid expensive damage later on. And when it comes to upgrading your
