The whole point of a combustion engine is covert the energy stored inside the fuel into power. If your priority is more power, then fuel-efficiency will drop after remapping. This includes an intercooler, bigger turbos, supercharger kit, intake, exhaust systems, upgraded injectors, methanol injection, etcĬlick the image below to check tuning box prices ⇓ Not to mention, several tuning companies have already engineered aftermarket parts for it. Moreover, they are quite receptive to hardware add-ons. Often, a Stage 1 tune is sufficient to satisfy your hunger. In my experience, VAG (Volkswagen, Audi, Skoda, Porsche, Lamborghini, SEAT) cars have lot of potential for remapping.

Revo Stage-1 dyno sheet for Octavia RS 2.0tsiĪs an example, Stage 1 Revo remap claims that 2018 Skoda Octavia RS (230PS and 350 Nm) can make 313-330 PS of power and 434 Nm to 488 Nm of torque. Stage 2, Stage 3 and Stage 4 require additional parts like an intercooler, free flow exhaust, intake manifold, bigger airbox, air filter, etc. A Turbocharged car, on the other hand, can start making around 25 per cent more power with just a reflashed ECU with Stage-1 map.įor most tuning companies, Stage 1 does not require any extra performance part. Unless someone adds performance parts to a naturally aspirated car, it’s not going to gain much with just remapping. However, turbocharged cars are a blessing for someone looking to remap their car. The latest crop of engines are mostly turbocharged due to companies moving towards smaller engines.Ĭar enthusiasts frown on this because a turbocharged car doesn’t sound good, power delivery is not linear, and rpm redline is also lower. There is no fixed percentage that can be gained by a remapping as some engines have more potential than others. How much power can I gain with remapping? This creates a power difference between different variants and car model that are using the same engine. Not to mention, the car manufacturer also deliberately detune to engines in the lower variant and models. This process of uploading a new map on the stock ECU is called remapping or reflashing. This often means that these ECU maps are quite conservative and a lot more power can be extracted from the same engine by uploading a new map. ECU takes input from sensors and processes it to give output.Ĭar manufacturers make this map keeping in mind the reliability, emission norms, drivability, and quality of fuel. This software is also called as the map (set of instruction written in the ECU).

Think of it as a computer that’s running software to operate an engine.

Will ECU remapping void the warranty? What is Engine Remapping?Īlmost all modern cars nowadays have an ECU (Engine Control Unit) that controls how the engine behaves.
