    BMW E46 Shark Injector Performance Software, 1996-2005 Models

    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 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 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 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, ignition timing, and VANOS control 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).

  • 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 M52TU 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 M52TU 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 E46 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.

    DBALZE, 323Ci: "The shark injector is awesome! After I put it in, I could definitely feel the quicker throttle response and more power throughout the acceleration curve. Definitely worth the money to me!"
    chrisct, 323Ci: "I installed an XXX short ram cold air intake and the shark injector on my 323Ci and I couldn't be happier. For me the biggest advantage was smoothing out the throttle response, but it definitely feels snappier."
    hqbmw, 328Ci: "This Shark really woke up my 328Ci. Cost per performance increase is as good as it gets! Also getting 10 to 15% better fuel economy in "normal" driving."
    huyner328, 328Ci: "First change I would like to mention is the increased throttle response, as soon as I shifted and floored it, the car would pull. From 3400rpms to about 5000rpms I think was the sweet spot that gave me a nice little grin on my face. Next I tested the Redline of my car, yup another grin on my face. I definitely noticed that the car moved a little bit quicker with not as much gas consumption on the MPG Gauge. Overall, awesome mod."

    E46 325 M54 vs. M56 Engines
    (click to expand)
    Does your 325 have the M56 "SULEV" Engine? Many of the 325's produced for the US -- particularly in California, Massachusetts, and a few other states -- came with a different engine, the M56 which meets "SULEV" (Super Ultra Low Emission Vehicle) emissions classification. A visual inspection of your engine (as shown below) is the best way to determine if your 325 has the M56 SULEV engine.

    E46 330i ZHP Rev Limits
    (click to expand)
    There are multiple versions of stock ZHP software and BMW used different rev limits in some of them. A ZHP automatic will always have a lower rev limit than a manual in the interest of preserving the automatic transmission. Our engine software will alter the rev limit set in the ECU but other limits in the auto transmission programming will maintain the factory rev limit. Manual ZHPs have stock rev limits that vary - some are set as high as 6920 by the factory software. The Shark ZHP software sets all manual tranmission rev limits to 6920.

    greekpsycho, 325i: "I sharked my 325 a few months ago and I noticed a huge difference. This REALLY brought out the best of my car."
    TJ710, 325i: "just did this to my own stock 325i about 3 weeks ago and I definitely felt a difference and it put a smile on my face."
    Dahmwern, 325Ci: "I'm definitely noticing a sweetly smooth power delivery, as well as a noticeable power increase in the low end as you being to accelerate (especially up moderate inclines). Note: This is NOT placebo effect. I drove the same route before and after to compare, and while its not perfectly scientific, it was quite obvious that there were some changes that took place - changes for the better. Like many mods, the car should have come this way!"

    Rob43, 330i: "besides the 7000rpm, removal of the top speed limiter, and very good(improved) throttle response, I got 6.5WHP on the dyno with my Shark injector. That’s worth $300 bucks in my book."
    xixixi, 330xi: "I got the shark for my 330xi, I love it. Shark > all. Why? It gives gains that other "custom tunes," can't. What I liked the most about my shark is shift points. If you can shift decent, you can stay in the 5.5k+ range."
    Douglas, 330Ci: "Just last week I had your Shark Injector installed in my 2001 330Ci. What a difference it makes! I already loved the car and it’s a great car to drive, but this takes it to a new level."
    Steve 330i: "I bought the software and CAI by Jim C. Installed both at the same time and have put around 500 miles on over the last month. The car is amazing to drive, and the software seemed to make the power band a bit flatter, less of a dip and a bit better at the lower RPMS."

    nleksan, 330i ZHP: "Ditch the Brand XXXXX software and switch it up for the newly-released Conforti Shark Injector for your car. It will give you a higher redline, no top-speed, more power, and much better throttle response, even over the Brand XXXXX."
    3579az, 330i ZHP: " The throttle response problem has been solved. I can now perform perfect rev-matches with ease, unlike before. I've been heel-and-toe downshifting all day with a major success rate of perfect shifts, which is a LOT more than could be said compared to stock. I can now pull cleanly through the rev range without feeling any hesitation or dead spots. I have confirmed that the dead spot that was painfully obvious before the flashing… is gone."
    pyreguy, 330i ZHP: "I have been VERY pleased with mine. The dead spot being irradiated was the best thing EVER."
    Scott, 330i ZHP: "Very increased acceleration - especially from around 3,000 to 6,000. The car feels like a bullet! It is the same smooth kind of power too - just more of it, delivered continuously to the top rpm. So 3rd feels more like 2nd gear now! Throttle transitions are much more refined. So when in low gears, on and off throttle changes are very seamless and smooth (no jerking) - and the change has made shifting gears easier - especially first to second. So now my car is much more fun to drive and shows engine performance that is better matched to the incredible handling ability it has. I'm very pleased with this upgrade and can't thank you enough!!!

    This performance software was developed specifically for the factory M3 Euro headers and stock Euro cats. Early in our E46 software development we found that the Euro headers and cats made a significant torque gain over the US spec but special software was needed to get the most out of them and to address some of the differences (Euro EGT sensor is in a different spot). The factory Euro headers and cats remain the top choice for performance and OEM quality.

    The T2 M3 software was developed during our 2-year campaign with the E46 M3 in the SCCA T2 club racing class (multiple wins and 3rd in 2006 Runoffs, highest finishing E46 M3) From 2013 the E46 M3 was reclassified to the T3 class. 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 rev limit is raised to 8,600 RPM rev limit and the top speed limiter is removed. By fine tuning these maps we've been able to improve the S54 engine beyond what BMW did by making more power and torque and a smoother-running engine. This software is a more aggressive tune than our standard street and Race software and additional engine maintenance and care is advised, including more frequent engine oil changes, oil analysis, valve adjustments, and other maintenance common to race-only vehicles. The minimum octane for this software is 93 AKI.

    The Shark Injector plugs into the diagnostic port inside the E46 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.

    Price: $349.00 (USD) 
    This USB cable is compatible with the newer version USB enabled Shark Injectors, which are distinguished by the small USB port located on the face of the device. In the past, when a Shark Injector owner needed an update made to his/her software, it required physically shipping the Shark Injector to Turner Motorsport for us to make the update for you. Advances made in the latest generation "USB" Shark Injector now make it possible for YOU to apply this type of update from your home computer, eliminating the hassle of shipping and waiting for your Shark Injector.

    This cable, when combined with any Windows based PC (or Mac running Windows via Bootcamp, VMware, Parallels, etc) and a SOON-TO-BE RELEASED Software Update application allows updates to be applied to the Shark Injector's programming. As periodic updates are released, we'll be able to email you updates to your Conforti Shark Injector, free of charge.

    Please note, this cable is NOT required to install the Shark Injector, and is only used when performing updates to your Shark Injector. Should you require updates to your Shark Injector at a later date, you may acquire the cable then -- or you may purchase the cable now to keep with your Shark Injector for future use, if needed (recommended).

    If you're planning on using the Shark Injector to add performance engine software to your BMW, a battery charger such as this one is required. The charger supplements the vehicle battery and provides uninterrupted power during the flashing process. This charger comes with a 20A boost mode for 30 minutes which should be enough time to complete the Shark Injector installation. Other chargers with manual power and timer controls are also acceptable (most shops will have a suitable charger for flashing vehicles).
