The Racemode Advantage: An Overview

Tailored Performance Calibration for BMW Platforms: Racebox specializes in custom performance calibrations designed specifically for your BMW, taking into account your unique modification list and preferred fueling options, including 91+ Octane and E-85 compatible fuel systems. For those using Racebox OTS (Off-The-Shelf) calibrations, your modifications are considered within the bounds of pump gasoline (non-ethanol fuels). Our meticulous engine tuning ensures optimal performance, maintaining OEM-level drivability and reliability.

Benefits of Racemode Tuning

• Enhanced Throttle Responsiveness and Drivability: Leveraging our extensive experience with hundreds of BMW tunes, we've developed a calibration that boosts throttle responsiveness and reduces lag inherent in stock ECM mappings.
• Rigorously Tested: Our tuning strategies have been honed over years, starting with our personal G80 M3, G20 M340i and A91 Supra test vehicles. Through a combination of dyno testing and real-world scenarios, we ensure our calibrations meet the driving conditions our customers will face, enhancing performance and reliability continuously.
• Precision Ignition Timing for High Octane Fuel: By optimizing engine timing for high-quality fuel, we extract maximum power safely and efficiently.
• OEM Safety Limiters Retained: We maintain and enhance OEM fail-safes within the ECU calibration, closely monitoring operation parameters to ensure drivetrain reliability, adjusting fail-safes to protect against the increased power output.

Additional Features

• Speed Limiter Removal: The ECU's vehicle speed limiter is deactivated, allowing for higher top speeds.
• Improved Fuel Efficiency: Our calibrations optimize fuel adjustments, potentially improving fuel efficiency with aftermarket intake and exhaust systems. Note: Increased throttle use may offset these gains.

What Makes Racebox Special

campaign

Our humble beginnings

Racebox was conceptualized when our founder Hussain Boxwala was trying to purchase a tune for his VR30 powered Q50 back in 2018. When speaking with tuners, he realized that there was a need for clear communication, honest work, and prompt response service. In an effort to create the best customer experience possible, Hussain set out to develop his first Q50 calibration on his personal vehicle.

100% Honest Marketing

Our main goal is to provide customers with the most realistic expectations for their vehicles. This means we'll never lie about the mods on our shop cars, the times they run, or the power they make. We aim to always provide the most information possible, like listing ambient conditions and correction factors on all dyno charts. We're not here to push an agenda, we're here to help you achieve your goals.
