Turner Shark Injector

[ra0507]

Anybody using the Turner Shark Injector for upgrading the software? I have read the instructions and it seems that there are so many steps that could result in making the computer a brick (if installed incorrectly), if it is installed correctly, it should be a nice upgrade. If any have installed it through the OBD connector, is it a simpler and less risky process than the instructions might indicate?

Never heard of it, what is it, and what is it supposed to do?

Here's the link for upgrade via the OBD port: https://www.turnermotorsport.com/p-3...re/?pdk=AQABEA

Apparently, they have one version of the software that also makes sport mode as the default mode. One also raises redline to 7400 rpm and you can choose 91 or 93 octane

I'll include some of their write up below:

Product Details

Unlock LOADS of torque and horsepower in all gears, especially 1st, 2nd, and 3rd
Choose between 91 and 93 octane
Quicker throttle response in both Sport and non-Sport modes
Stock 7000 or Raised 7400 rev limit
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 23 hp at 6100 rpm and 19 lb/ft torque at 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.....

I installed the Turner Shark Injector and I would guess their estimates of 23 additional hp and 19 lb/ft torque are correct (see above) but I don't plan to prove it. It seems more powerful, but certainly doesn't change the character of the engine. They may be running a special price in December.
