Product Details

Performance software is a must-have upgrade on your Z8 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 Z8 performance software was developed alongside the E39 M5 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! The rev limit is raised to 7,400 RPM and 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 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.

The Shark Injector plugs into the diagnostic port inside the Z8 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.

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.
Sport Mode Memory. This option will remember if you left the car in Sport Mode or not. When you restart the car it will be in the last setting you used. This is perfect for owners who use Sport Mode all the time. You won't have to remember to press the button each time you start the car.
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.
Note: not all combinations of product options are available. We will contact you if there is a conflict.

Read what others are saying!

briandilley: "The shark upgrade is fun, love the RPM upped to 7300 and the mid-range throttle is great and I still have a SPORT button option. I even think the retune leaves less smoot on the tailpipe. I always was suspicion of the black smoot as an engine that wasn't tuned correctly. No more smoot after a 4 hour jaunt."

Z8doc: "Decided to purchase the Conforti Shark Injector software into the Z8 last week. All in all a very easy thing to do and just about anyone should be able to do, even if you have a minimum of skills. For me, the overall responsiveness and driving pleasure is greatly enhanced and in sport button off mode, is similar to the OEM Sport Button ON setting so when you push the Sport Button now, you REALLY feel the change in Throttle response in the seat of your pants. Again, this will probably change from person to person a bit. It is relatively cheap upgrade (less than $400 including shipping) and given how easy it is to install, I give it a 2 thumb up approval. If you have the Dxxxn Stage One, this is an improvement over that as Stage One only changes the rev limiter and eliminates the top speed limit. The Conforti actually changes the thottle body response too and you definitely notice it."
