E82 128i, E9X 328i, E60 528i Stage 1 Performance Software
Performance software for the N52B30M0 engine in the 128i/328i/528i.
The original factory software in your BMW has been engineered for emissions compliance and mass market appeal, leaving performance out of the equation. The N52 engine in the E82 128i, E90/E91/E92/E93 328i, and E60 528i is a detuned version of what was available in other models and software tuning is part of the solution to getting that power back.
Our Stage 1 software is for tuning a stock 128i/328i/528i or for very basic intake and exhaust mods. Stage 2 software is also available to tune for the popular 330i intake manifold upgrade. In both stages we tune the engine for higher octane fuel. BMW deliberately de-tunes the car for lower octane that we have in the US. This naturally leaves some room for improvement if you only run 91 or higher octane fuel. We tune the ignition, camshaft, and VANOS values to optimize them for better fuel. We also adjust the fuel maps to match the more aggressive timing and remove or raise the artificial torque limiters. Our software produces more horsepower and torque and a smoother-running engine. We don't just tune for full throttle either - there is more torque available in the mid-RPM as well! Throttle response is also improved.
We have been partners with Epic Motorsports for BMW performance software for over ten years. They are one of the very best BMW ECU tuners in North America. Our custom performance tune for the 128i/328i/528i combines these years of BMW performance tuning, racing and track events, and ECU tuning into this fantastic N52 software upgrade.
Our software is installed via the Engine Calibration Interface (ECI) and your Windows laptop (compatible with XP, Win7, Win8, and Win10). The ECI cable is included at this price. Read and email your stock file and a tuned file will be returned to you. This is better than off-the-shelf tunes that never look at your original software.
