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 M52/S52 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 M52/S52 engine beyond what BMW did by making more power and torque and a smoother-running engine.

The Shark Injector plugs into the diagnostic port under the hood of the E36. 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.

Anonymous, 323is: "I purchased my first Shark for my 1999 - 323is (e36). I installed it during work today and had a GREAT time driving home on I495. My wife actually had to call me to find out what was taking so long. She didn't know I was having the most fun I've had since I first purchased my BMW! I would definitely recommend this new product to all the 323is owners."

Gary, 328i: "I own a 1997 328i and recently installed the Conforti Shark Injector and Intake Kit, as well as a Borla exhaust and a B & M sport shift kit. I am very impressed with the amount of performance I was able to gain."

Manny, E36 M3: "Just "sharked" my E36 M3. All I can say is WOW. The car has never run so well. The idle and the engine overall is so smoooooth! The throttle is very responsive, power is right there. Very Nice! Never putting it back to stock! Just wanted to say job well done, and thanks."

Josh, E36 M3: "Just got done putting on my Supersprint exhaust, Shark injector and my intake, wow what a difference. Thank you guys for the performance, I will be a lifetime customer."
