  • Performance software is a must-have upgrade on your BMW 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 M54 performance software was developed on the dyno to create maximum power and torque using premium 91+ octane fuel while maintaining BMW reliability and smoothness. 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. We also raise the rev limit to 7,000 and remove the top speed limiter. By fine tuning these maps we've been able to improve the M54 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 Z3 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.

    kniffin50: "Best thing I did to my 2001 3.0. I like the smooth take offs and the new power bands."
    z3RIFFRAFF: "I have a 2002 3.0 that I sharked without any problems. The only thing you will regret is waiting so long to do it!"
    bigbird: "I installed my Conforti Shark injector yesterday. My impression after about 30 miles of driving is that the throttle response is quicker. I also like that the rev limiter no longer interferes with a quick row through the lower gears. It seems to idle a little higher, too. The overall feeling is of more and quicker "punch" when you nail the throttle. It's not a night-and-day kind of a difference, but most definitely noticeable. My wife drove the car about 50 miles and she said that it shifts smoother, is more responsive and even feels a little faster. One more thing; the install was painless and the directions were very good."
