    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 = up to 8600 RPM

    Our Race software was co-developed along with our cat-delete Test Pipes and our IMSA E92 M3 racecars. Dyno-tuned and race-proven, this software will get the most from a cat delete upgrade on the E9X M3. The combination of the software and Test Pipes produces over 40hp and 30ft-lbs with no other modifications - a massive gain on an already impressive engine.

    Our Race software has been fine-tuned over the years beginning with our IMSA/CTSCC E92 M3 racecars (2011 GS class champions). We modify over 40 different maps in the ECU for such things as fuel and timing maps at part throttle and full throttle, revised torque settings, knock control, VANOS and cam timing, pedal input, top speed limiter, and rev limiters. Additional tuning has been done for the cat delete - prevent limp mode and check engine lights, fault codes for cat delete, and turning off the secondary air pump. Turning off the secondary air pump also disables the cold start sequence so your idle and warm-up will be smoother and quieter. Not only is there a lot more power at all RPM but the engine is more responsive and smoother!

    The Race software is only for cars with the primary cats removed via Test Pipes or similar race exhaust. We developed this along with our own Test Pipes but the software can also be used with other brands of cat-delete pipes as well. See links to other race exhausts we sell in the Additional Items menu below. In addition to our own Test Pipes we have used our software with the Akrapovic Evolution exhaust, Supersprint sport cats, aFe race center pipes, Borla Test Pipes, and others. 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.

    E9X M3 Stage 2 Power Gains:
    Spec Power Gain Torque Gain
    Software upgrade alone +17hp +16ft-lbs
    Software and Test Pipes +41hp +32ft-lbs

    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.
    240E Update
    (click to expand)
    Ideally you should be running the latest software from BMW - version 240E or 241E. BMW released several software updates for the E9X M3 with significant improvements with each release. The 240E/241E are the latest BMW software versions and have a lot of improvements in drivability and torque settings than older versions. The 240E upgrade can be considered a software upgrade on its own. Your BMW dealer should be able to provide a 240E/241E update at no charge. All of our software is based on the 240E update but we can incorporate its changes into older versions or give you a free update with the purchase of our Race software. If you're already on 240E there is no reason to switch to 241E (the tuning maps are the same).

    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).

    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.
