Shark Injector E46 M3, MZ3 Shark Injector Race Software (for Headers and Cat Delete) TMS158

E46 M3, MZ3 Shark Injector Race Software (for Headers and Cat Delete)

Shark Injector Performance software includes:

  • Tuned for headers and no cats
  • Horsepower and torque gains
  • Faster and smoother throttle response
  • Top speed limiter removed
  • Extremely easy to install/uninstall
  • Reversible and reusable

Performance software is a must-have upgrade on your E46 M3 and you won't find an easier and better software solution than the Shark Injector. Developed by BMW tuning expert Jim Conforti, this device plugs into the car's diagnostic port and flashes new performance files into your car's engine computer (ECU). There's no removal of the ECU and shipping, no cables, no laptop required - only a battery charger! Installation takes just a few minutes and your engine will perform like never before!

The M3 performance software was developed on the dyno to create maximum power and torque using premium 91+ octane fuel and revising the torque limiters in the ECU. The software makes changes to the ECU's maps and algorithms for fuel injection, ignition timing, VANOS and camshaft movement, and transitional fueling. We modify the maps for part throttle and full throttle so you get better response and more torque at all RPM. The rev limit is raised to 8,100 RPM rev limit and the top speed limiter is removed. By fine tuning these maps we've been able to improve the S54 engine beyond what BMW did by making more power and torque and a smoother-running engine.

The Shark Injector plugs into the diagnostic port inside the E46 cabin. With the battery charger supplying power, press the Upgrade button and within minutes the ECU is reflashed with the new performance tune. No other software product on the market comes close to how easy it is to install. You can use the Restore button to re-install the stock BMW software at any time. Detailed instructions are included. Other tuners require you to remove the ECU and ship it to them or use a laptop to read and write a new file. The Shark Injector is ready to install right out of the box! A planned future upgrade will allow you to use the USB port to load different performance files.

E46 M3 Dyno
Power and Torque Gains (stock header config)
Stock: 278.2 whp / 235.3 wtrq
Sharked: 284.2 whp / 236.9 wtrq
Peak Gain 6.0 rear wheel HP and 1.6 rear wheel Torque
(note: the max gain (biggest improvement) is 9 rear wheel HP between 7000 and 8000 rpm)
The software for running without cats includes special programming tweaks that will ignore certain readings from the post-cat O2 sensors and rely on the data from the first set of O2 sensors and the EGT sensor. The post-cat O2 sensors must still remain in place in the exhaust.

Looking to maximize your power gains? Add a Turner IAT Relocation to combat power-robbing heat soak - the only true plug-and-play solution available. Heat soak is a real plague on consistent power for a stock or tuned vehicle.Click here to read more about our IAT relocation kit.
