    Turner Stage 2 Race Software for E9X M3
    Part #: E9X-M3-SOFTWARE-STAGE2

    As used on the Lime Rock M3
    Max HP gain = 17* hp @8200rpm
    Max Trq gain = 16* ft-lbs @6900rpm
    Rev Limit = 8300 or 8600 RPM

    This special Race software is designed to work with a Test Pipe, or other front exhaust section that eliminates the primary catalytic converters. On our own M3 project vehicles, this combination netted 40hp and 32ft-lbs of torque* - a massive transformation to an already impressive output. Our Race software makes use of the same features of our street legal Stage 1 software - fuel and timing maps at part throttle and wide-open throttle, revised torque settings and knock control, VAN0S variable valve timing, with the added benefit of using a racing exhaust without the front or back catalytic converters. This software has specific changes for the cat-delete to turn the check engine light off and prevent the car from going into limp mode. An optional 8600 RPM rev limit is available (stock is 8300). This product is for the software only and should be combined with our front cat-delete pipes (click here) or similar front-cat delete section. 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 for manual transmission cars and the top speed is raised/eliminated in manual and DCT models. We recommend getting the latest BMW software from your dealer (code 240E) but we can include many of the 240E enhancements in your existing file.
    * = software alone, +40hp/+32ft-lbs when used with Test Pipes that remove the primary catalytic converters.

    If you have other modifications done to your M3, we can supply you with specially-developed software to maximize the gains from those upgrades. Click on the blue banners below to see more detailed information on the software options we offer. Select all those that apply in the menu below.

    Stage 2 Race Software Options:
    Minimum Octane
    (click to expand)
    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. Note that if you're using 93 you must never use anything lower without the help of an octane booster (and then not for very long).
    Rev Limit
    (click to expand)
    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. Work is continuing for a higher rev limit on DCT models.
    Disbale Cold Start
    (click to expand)
    This feature is for off-road/track driven cars only. Under the factory programming, an air pump will start when the engine is started. This is to pump fresh air to mix with the rich fuel mixture and heat the catalytic converter faster. The air pump stops running when the engine gets to a specified temp. Unfortunately, the air pump system adds a very harsh and loud tone to the exhaust. The effect is made worse when the catalytic converters are removed (such as on a track or race car). What we can do in this situation is disable the air pump system so it does not activate when the engine is started. You get a super smooth and quiet startup that is a night and day difference compared to the original. This feature should only be used on cars that have had cats removed because the overly rich fuel mixture will degrade the catalytic converters much quicker.
    Oxygen Sensors
    (click to expand)
    Most race exhaust systems include O2 sensor bungs for pre and post-cat oxygen sensors. In this case we recommend using all four O2 sensors (even if the post-cat sensors are not monitoring anything). However, on some systems there is no provision for the rear O2 sensors and we will need to make further adjustments in the software to accommodate this.

    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).

    This software is a reflash of your computer. The computer will need to be sent to Turner Motorsport for the installation. Click here for specific instructions on shipping the computer. If you are unsure of how to ship your computer, we can provide you with a shipping packet. Return shipping is by UPS Ground but Express shipping is available.

    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.

    At first, the software wasn't compatible with my year of M3, an early production model. However, the turner team worked very hard to make it work and when it did... boy did it work. Overall I'm very pleased with this software and the cat delete as well, and I'd recommend it to anyone and everyone with an M3.
