Shark Injector Software (Race Version) 1999-2006 BMW M3 [E46] & S54 Z4M Coupe/Roadster [E85]


Quick Overview

Sku # : Shark_RaceVersion_S54_MW
Minimum Octane
Rev Limit

The Race Shark Injector software has been specifically designed for E46 M3's running headers and a racing exhaust with no catalytic converters. We recommend the factory BMW Euro headers because the fitment and quality is excellent and have been shown to produce a good amount of power gains. The secret to the Shark Injector Race software is that you can eliminate the back pair of oxygen sensors (remove them from the car). The DME will then rely on the front pair of O2 sensors and the stock EGT sensor only. Give your M3 a boost in power with a Shark Injector Race Version.


  • Removal of the top speed limiter
  • Choose between 8100 and 8600 RPM rev limit
  • Improved throttle response in sport and non-sport mode
  • Smoother torque curve
  • Choose between 91 and 93 octane mapping
