A Stage 2 remap is an engine tuning process performed on a vehicle’s ECU (Engine Control Unit) that requires hardware upgrades to fully leverage the software improvements. This process typically includes enhancing the turbo boost pressure, adjusting fuel injection timing and duration, and optimizing the air-to-fuel ratio.
The primary goal of a Stage 2 upgrade is to boost vehicle power and performance. While Stage 1 calibrations can improve both fuel economy and power, Stage 2 is focused solely on enhancing performance.
Stage 2 remaps are frequently applied to turbocharged petrol and diesel engines, representing a step beyond Stage 1 remaps, which involve software adjustments only and do not require hardware modifications. To accommodate the increased drivetrain load from the enhanced engine output, various hardware upgrades are necessary for a Stage 2 remap, depending on the specific vehicle being tuned.
As mentioned earlier, a Stage 2 remap is a more powerful and aggressive version of a Stage 1 remap.
A Stage 1 remap is often performed to enhance the vehicle’s driving experience by improving throttle response, increasing BHP/Torque, and reducing turbo lag, along with better fuel economy. When driven sensibly, a Stage 1 remap can improve engine fuel efficiency, making it a popular choice among remap customers for this reason. However, a Stage 2 remap elevates these performance enhancements to a level that stock vehicle hardware cannot handle safely, necessitating hardware upgrades.
Think of it this way: Stage 1 tuning is suitable for everyday street driving, offering a better driving experience and improved fuel economy. In contrast, Stage 2 tuning is for those seeking dramatic performance gains, aiming to build a track-worthy road car.
The primary difference between a Stage 2 and a Stage 1 remap is the power output. A Stage 2 remap can provide a 30% to 50% increase in power over factory settings, whereas a Stage 1 remap typically offers a 15% to 20% power increase. However, each vehicle responds differently to tuning software, so it’s crucial to consult with a professional tuner to understand the potential power gains for your specific vehicle.
We understand that vehicles can differ due to variations in manufacturing and wear and tear. Prior to conducting Stage 1 or 2 Remaps, we perform a thorough diagnostic check of the entire vehicle using advanced tools from Autel and Launch. This includes scanning for any underlying fault codes and conducting visual inspections of the hardware to confirm its proper functionality and suitability for tuning.
