BMW is known for its precision engineering and performance potential. At RAT Remaps & Tuning, we specialise in bringing out the best in BMW’s petrol and diesel powertrains, delivering sharper acceleration, more torque, and enhanced drivability without compromising reliability.
BMW engines particularly turbocharged units are often under-tuned from the factory, leaving significant performance on the table. With a custom ECU remap, we optimise fuel injection, ignition timing, boost pressure, and torque limits, unlocking performance that rivals higher-tier models in the same range.
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.
