Bonneville Motorwerks
Performance Software

Bonneville Motorwerks tuned engine performance chips, developed by Motronic expert Jim Conforti, provide the ultimate in performance. The modified Motronic software, optimized for 91 or higher octane gasoline, adjust the ignition timing and fuel curves which results in increased performance. We have dynoed these chips and compared it to all the others and found it to provide the most HP and usable torque.

Cars produced up to 1995 require a performance chip.   
Cars produced from 1996 onwards (OBD-II cars) require Shark Injector.

The Shark Injector is a proprietary (patent pending) handheld reprogramming device for OBD-II equipped BMW automobiles.  It allows the vehicle owner to reprogram their own vehicle at will, with the contained performance programming.  Later, they may return the vehicle to stock if so desired.  Removing the DME to load performance software, disabling the car for 3 days minimum is no longer an issue! 

Its unique design allows it to be used an unlimited amount of times on ONE specific BMW vehicle.  Once it is used on one BMW, it is "locked" to that vehicle's computer VIN and will not be able to program other cars (even if it's the same model).

Often times, a dealer will update the software on your factory DME unannounced, over writing the performance software.  No problem!  Just reload the performance software with the Shark Injector!

The Shark Injector is 100% compatible with any cold air intake system for even MORE horsepower and torque!
