The Shark Injector is an amazing hand-held unit that plugs into your car’s 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 – offering features and results that other upgrades simply cannot touch.

The newly updated Shark Injector includes its own USB port, allowing you change software if necessary (between different octane ratings).

Easily reversible to stock software leaving no trace.


[ ] Not compatible with automatic transmissions
[ ] US models only.

Why you will love this product:

  • More power and torque, particularly in the mid-range from 3500 RPM to redline up to 15hp
  • 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
  • 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 
  • 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 won’t 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, and ignition timing to take full advantage of 91+ octane fuel. BMW ‘de-tuned’ 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 car’s On Board Diagnostic (OBD) port, located under the dashboard in most cars. At the push of a button the Injector begins communicating with your car’s computer. The Shark handles everything from that point on – 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).

The Shark Injector CANNOT be shared or used on multiple cars. Once installed, it belongs to the specific car.

Please note that Shark Injector software is offered in both high and low octane fuel tuning versions. You should order your Shark Injector with an octane rating that is compatible with the level of octane/quality of fuel available in your area.

Select Octane rating.

NO RETURNS ON THIS PRODUCT UNLESS THE PRODUCT IS DEFECTIVE. (Standard Mini Mania policy for electrical components.)

Will this upgrade go with 380cc injectors?
The NME4101 Shark Injector ECU upgrade is not optimized for the JCW 380cc fuel injectors, but the computer will adapt to the larger injectors. So yes, the Shark will work whether you have the stock or JCW injectors.
