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. Choose between a stock or raised rev limit. 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.

The Sport Mode Memory option will remember if you left the car in Sport Mode or not. When you restart the car it will be in the last setting you used. This is perfect for owners who use Sport Mode all the time. You won't have to remember to press the button each time you start the car. The Sport Mode button functions the same as before so you can turn Sport on/off at any time. The software will remember which one you left it in.
