Unleash Hidden Power with the Shark Injector for Your BMW

The Shark Injector is the ultimate solution for effortlessly boosting power and torque in your BMW. This software, meticulously dyno-tuned by BMW tuning legend Jim Conforti, is engineered to optimize high-octane (91+) pump gas, enhancing mid-range torque and high-RPM horsepower. It delivers an elevated level of performance without compromising your BMW's integrity, making it the easiest way to unlock untapped potential.

Key Features:

• Dyno-tuned by BMW tuning legend Jim Conforti
• Raises the rev limit for increased performance
• Fine-tuned fuel and spark maps for superior engine responsiveness
• Easy plug-and-play installation with detailed instructions
• Compatible with high-octane pump gas (91+)

The Shark Injector is meticulously designed to safely improve performance while enhancing driveability and responsiveness. Installation is a breeze - simply connect a battery charger to ensure your car battery has backup power, plug in your Shark Injector, and initiate the process with the push of a button. While the Shark Injector replaces parts of the stock software, it also stores the original data in the unit for future use if needed. When the LED changes from red to green, you're ready to experience your BMW's enhanced performance.

The BMW M52TU engine is already finely tuned, but there are still ample opportunities to elevate your driving experience. Jim Conforti has expertly fine-tuned this Shark Injector to enhance various aspects, from fuel maps and ignition timing to VANOS operation. The result is an impressive addition of 15 HP and 12 lb/ft of torque. Engine response is significantly improved, and the rev limit is raised to 7,000 RPM. Additionally, the speed limiter is removed, unlocking your BMW's full potential. Enjoy a vastly improved driving experience, especially during part-throttle and wide-open throttle acceleration.

Performance Gains:

• +15 HP at 6,200 RPM
• +12 torque @ 3,500 RPM
• Rev limit raised to 7,000 RPM

It's important to note that Shark Injector software is ONLY compatible with NORTH AMERICAN SPEC BMWs and is not designed for EURO-SPEC BMWs.

Shark Injector Performance software includes:

• Unlock LOADS of torque and horsepower in all gears, especially 1st, 2nd, and 3rd
• Race Software for Headers/Cat-delete
• Choose between 91 and 93 octane
• Quicker throttle response in both Sport and non-Sport modes
• Top Speed Limiter Removed
• Choice of several options to make driving your M5 more enjoyable

Performance software is a must-have upgrade on your E39 M5 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 M5 performance software was developed on the dyno to create maximum power and torque using premium 91+ octane fuel and revising the torque limiters in the ECU. 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. The stock software artificially limits torque output, especially in the first three gears. We raised the torque limiters in all gears so there is more torque available. You will see an immediate difference as soon as you leave your driveway! Choose between a stock 7,000 or raised 7,400 RPM rev limit. The top speed limiter is removed. By fine tuning these maps we've been able to improve the S62 engine beyond what BMW did by making more power and torque and a smoother-running engine. 

Gains of up to 23 hp @ 6100 rpm and 19 lb/ft torque @ 5000 rpm!!!
We used several E39 M5s on our dyno to establish what the average/typical power numbers are. The dyno charts on the right are from the same car - a 2003 E39 M5 that was already equipped with intakes, mufflers, and running 93 octane. For our Shark Injector dynos we made baseline runs with the stock software and then runs in 3rd gear and 4th gear. The only changes to the car was the Shark Injector software. Why did we post dyno runs in different gears? The 3rd gear run shows the torque gain with the new torque limiters in the software. The 4th gear run is posted to be consistent with the industry-standard of dyno-ing cars in 4th gear. Note: comparing dyno results and wheel horsepower numbers from one shop to another is not advised. What really matters is the gain from stock to modified from the same car on the same dyno.

Product Options: 
Octane: Choose either 91 or 93 minimum octane. For 93 we can be more aggressive with the timing and get more power. But you must have 93+ octane available, using the 93 version with anything less is not recommended. 
Throttle Setting: Choose an aggressive throttle response or a smoother, linear setting. The Shark enhanced throttle will be much quicker and more in line with the Motorsport inspiration of the M5. The Euro throttle is more linear in response and smoother than the stock US or Shark throttle. The Euro throttle is also known as the 'M5Board tune'. Our customers are split 50/50 so there is no "best throttle" mapping - it's personal preference. 
Rev Limit: Choose a stock 7,000 RPM or raised 7,400 RPM rev limit. The raised rev limit is great for track or autocross where you can stay in gear longer and avoid untimely upshifts. The stock rev limit is for the non-track customer who wants all of the other benefits without the need to rev beyond the stock setting. 
DSC/Sport Mode: This option will make Sport Mode active only when DSC is turned off. The Sport Mode button is disabled altogether so the only way to get Sport is to disable DSC. 


The Shark Injector plugs into the diagnostic port inside the E39 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.

Looking to maximize your power gains? Add a Turner IAT Relocation to combat power-robbing heat soak - the only true plug-and-play solution available. Heat soak is a real plague on consistent power for a stock or tuned vehicle. Click here to read more about our IAT relocation kit.

This part alters or deletes the emissions equipment on your car. Because of this, we require a waiver of emissions compliance to be signed and sent in to TMS. You can download the waiver here.

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!
