The easiest software flashing tool in the world! Power & Torque Upgrades in Minutes!

The Shark Injector is an amazing hand-held unit that plugs into your caraEURtms diagnostic port and re-flashes the computer with performance software. The software was developed by renowned BMW tuner Jim Conforti, who has nearly 20 years of BMW engine tuning experience. The Shark Injector is one of the safest and most cost-effective enhancements you can do aEUR" offering features and results that other upgrades simply cannot touch. The Shark Injector will also be upgrade-able through its own USB port, allowing you to upgrade to different software as your needs and modifications change (under development).

Why you will love this product -
+ more power and torque, particularly in the mid-range from 3500 RPM to redline,
+ quicker throttle response, giving the car a snappier feel,
+ a safe increase in rev limit (great for staying in gear just a little longer)
+ smoother-running engine with fewer hesitations and dead spots
+ top speed limiter removed
+ true DIY install with step-by-step instructions (no downtime while your computer is shipped somewhere else for the install)
+ Upgrade and Restore features to install/uninstall on the same vehicle
+ Upgrade-able via USB connection with your PC - add a file to better suit your mods (under development)
+ Retains all of your diagnostic, service, maintenance systems and won't interfere with your normal maintenance routines

This software is a major refinement of the stock software. It makes the car much easier to drive with less hesitation, more torque, and incredibly smooth operation. A lot of tuning has been done at the low RPM ranges to improve response. The car wonaEURtmt hesitate or lag, making the car easier to drive. And with the extra torque you can drive in a higher gear and not have to downshift as often. Theoretically this means better fuel mileage too!

How does it work? The Shark Injector makes changes to the stock BMW software in the areas of fuel enrichment, transition fueling, camshaft timing, ignition timing, and VANOS control to take full advantage of 91+ octane fuel. BMW aEUR~de-tunedaEURtm cars for the North American market in the event inferior fuel was used. We reverse those changes to gain more horsepower and torque. 91 or higher octane fuel must be used.

How does it install? The Shark Injector plugs into your caraEURtms On Board Diagnostic (OBD) port, located under the dashboard in most cars. At the push of a button the Injector begins communicating with your caraEURtms computer. The Shark handles everything from that point on aEUR" reading and copying the stock software, re-loading its own performance version, and checking its work along the way. The whole operation is completed in under 20 minutes. A battery charger with a continuous 10-20amp charge is required (available below if you do not currently own one).

You may be able to upgrade the Shark Injector file to another version to better meet your tuning needs. Depending on the model we may have better tunes for things such as intakes, larger air sensors, camshafts, headers, and others. For a small fee the current Shark Injector tune can be removed and a new file added instead (the original Shark file you were using would no longer be available). To do this, we need the car restored to stock settings with the current Shark Injector and then returned to us (updating via USB is not yet available). Sharks that were not Restored to stock cannot be upgraded and the unit will be returned to you (at your expense). We also perform other work on the Shark Injector while it is here, including diagnostic tests and re-packaging with the most current instructions. The Shark that you get back is virtually new and ready to be reinstalled!

To get started, review the catalog of current Shark Injector files for one that better matches your tuning spec.
1. Enter the new tuning file in the form below. Include any other relevant information.
2. Click the Update Price or Add To Cart button.
3. Complete the online transaction with your address and payment information.
4. A Turner Motorsport sales rep will contact you after your order has been submitted. Do not send in your Shark Injector until someone has contacted you with a reference number and return shipping address.

Turn-around time for upgrades is typically the same day we receive it. UPS Ground is the normal return shipping method unless you specify faster shipping on your order.

  • Shipping Instructions - specific instructions for packaging and shipping. Also includes a contact form to include when you send back your Shark.
  • Emissions Waiver - some tunes require this emissions/smog waiver before we can program the new file to your Shark. These are noted in the catalog listing in the links above. Print and include this Waiver when you send in your Shark.

  • Unlock torque and horsepower
  • Smoother engine with less hesitation
  • Improved throttle response
  • Rev limit increased to 7000
  • Top speed limiter removed
  • Installs in minutes!
  • 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 Z4 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.
