At RAT Remaps & Tuning, we specialise in unlocking the hidden potential of your vehicle’s engine with our expertly developed Stage 1 ECU remapping solutions. This is the most popular and widely recommended upgrade for both petrol and diesel vehicles — designed to safely increase power, torque, and drivability without the need for any hardware modifications.
A Stage 1 remap is a software-only upgrade to your vehicle’s Engine Control Unit (ECU). Every modern engine is controlled by an ECU, which manages fuel delivery, ignition timing, boost pressure, and numerous other parameters. Manufacturers set these parameters conservatively to account for varying fuel quality, climates, and driving conditions worldwide.
