Adding power and torque to your M3's V8 is as easy as a flash! Where we can make our software better is by tuning it for higher octane gasoline. The stock software is tuned around the 87 octane available in the US (not that most people would use 87 but BMW engineers must account for that possibility). With our software, the performance of the S65 engine is optimized for the higher 91 or 93 octane. We tune many areas of the engine programming - fuel and timing maps at part throttle and wide-open throttle, revised torque settings and knock control, VAN0S variable valve timing, and more. The throttle response is also improved (quicker and smoother) eliminating unwanted and dangerous flat spots in the factory pedal response. We also offer raised rev limits and the top speed is raised/eliminated. Our software uses the factory 240E update as a base. The 240E has several major enhancements over previous factory file versions. No worry if you don't have 240E - we will provide you with a free update before the Turner performance software is installed. If you have other modifications done to your M3, we can supply you with specially-developed software to maximize the gains from those upgrades.

Turner Motorsport has been developing software on the S65 since our first car in 2008. Since then we have done software projects for street, track, full-race, stroker, and supercharged engine builds using the stock MSS60 DME or a stand-alone Bosch or Motec system. Engine tunes have been developed and checked on our Dynapack chassis dyno and further refined with real world testing. For track cars, our Stage 2 cat-delete software will clear check engine lights and faults (to satisfy race series regulations).

Our software is installed via the Turner flashing OBD tool. This tool plugs into the OBD socket in the dash and the performance software is installed from a laptop computer connected to the tool. It also works as a fault code scanner to read and reset diagnostic trouble codes and reset adaptations. The software program requires a Windows XP/Vista/7/8/10 laptop and the installation and setup are very easy (click here for instructions). The OBD tool, cable, and files are shipped to you with simple setup instructions. There is no need to remove your ECU and ship it. You can have your M3 flashed in under an hour from the convenience of your garage or driveway!

Stage 1 Performance Software Options:

Minimum Octane
You can choose between 91 or 93. We have developed tuning for the standard 'high octane' premium fuel found around the country (91 is the maximum available in some areas). Our power and torque gains are advertised with 91. If using 93 we can alter the knock sensor logic to extract more power with the higher grade fuel. Additional race fuel maps are also available, contact us for details.

Rev Limit
On 6-speed manual cars we can set a higher engine rev limit. 8,300 is stock; 8,400 is what was used on the GTS model in Europe; 8,600 is the safest raised rev limit that we have used in our race cars. To make things simple we offer it as either stock 8,300 or raised to 8,600. On DCT cars the higher rev limits are for M shift modes only (manual/paddle shift). The higher revs do not work in full auto D modes. Work is continuing on higher limits for D mode.

Launch Control
Our software can also enable a Launch Control feature. To use it, activate M Dynamic Mode, engage first gear, hold the throttle to the floor (it will only rev to 3,500 RPM), and dump the clutch. Keep your foot to the floor and hang on! You don't have to modulate the clutch and throttle - the engine and DSC modules will handle the launch. We experimented with different launch points and found that 3,500 RPM offers a great combination of tire hook-up and torque output. This is available on manual transmission cars only (DCT has their own built-in launch control).

M Dynamic Mode Steering
We can set the M Dynamic Mode (MDM) steering effort as the standard steering. The MDM steering is heavier and requires more effort when driving at higher speeds. Some owners feel that the standard steering is too light and over-boosted and the MDM steering is a nice change. This does not affect the steering effort, or the other features, of MDM.

240E Update
Our performance and race software is built around a specific version of stock BMW software (version 240E). It was released towards the end of M3 production and includes a number of significant changes over older versions for drivability and torque management. 240E was such a big step forward that it's considered an upgrade all on its own. No worry if you don't have 240E - we will provide you with a free update before the Turner performance software is installed.

In 2015 BMW released a 241E update. There are minor changes to the software code but the tuning maps and data are all the same as the 240E version so there is no need to update to 241E. If the dealer offers it we recommend that you decline. If you're already on 240E there is no reason to switch to 241E (the tuning maps are the same).
