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. 

Helpful Links:

  • Shark Injector File List - listing of all Shark Injector files by vehicle model. Select a file from this list to upgrade to.
  • 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.
