BMW E91 Performance Flash Software, 2005+ Models

BMW E91 Performance Flash Software, 2005+ Models The Fastest Way To More Power - Up To 120hp!!!

Our Performance Software makes more horsepower and torque with no downsides! Performance software is the icing on the cake, the finishing touch, or the capstone for your BMW tuning project. Software ties it all together - maximizing output from upgrades where the factory software can't keep up. The factory software is actually programmed around 87 octane which de-tunes the performance of the car. Our software is set to 91 as a mimimum, allowing us to be more aggressive with the programming. We can refine and adjust the factory limitations, opening up the potential for more horsepower or refinement from your current upgrades. We also tune the software to fix defects and rough edges in the stock software, making the car easier and more enjoyable to drive.

We have been tuning BMW software since 1995, making us one of the most experienced BMW tuners in North America. Over the years we have experimented and tested many different forms and brands of performance software, including developing our own on our Dynapack chassis dyno. Our Performance Software catalog includes tunes and upgrades that best suit your BMW and your upgrade goals.

Turner Motorsport Performance Flash Software features:
+ dyno developed, real-world tested
+ ignition and fuel timing adjustments
+ cam timing, including VANOS and Valvetronic
+ raised rev limit*
+ top speed de-limited*
+ part throttle and full throttle mapping
+ improved throttle response
+ specific software for most major upgrades - cold-air intakes, sport exhaust, etc
+ race software for removing catalytic converters**


* - on select models
** - not legal for street use, emissions liability waiver required

Turner Performance Software for E9X 325i

MORE POWER, BETTER DRIVEABILITY!
Max HP gain = 21 hp
Max Trq gain = 19 ft-lbs
Rev Limit = 7000 RPM

Our software fully maximizes the 'high-output' N52B30K0 engine in the 325i. Our software has been carefully developed on the dyno and the road to provide optimal power and torque gains at all RPM. We change the fuel, Valvetronic, and VANOS maps as well as revise the factory torque limiters. We have paid particular attention to increasing low and mid-range torque. The stock BMW software is hampered by settings for 87 octane fuel. By re-mapping the engine programming for 91 octane, we can make more power, torque, and improve fuel mileage - all without harm to the engine or affecting driveability. The throttle response is also improved (quicker) eliminating unwanted and dangerous flat spots in the pedal response.

The E90 325i benefits from two Stages of tuning -
Stage 1 - stock intake manifold, just a software upgrade
Stage 2 - 330 intake manifold with matching software upgrade. The 330 manifold is a direct bolt-on to the 525i engine and provides an additional 30hp on top of the software tuning. More torque is available as well thanks to it's 3-stage DISA system. Since the rest of the engine is the same, this gives you 330-levels of power and torque!

There are two ways to install our software: mailing the ECU to us for a reflash or do-it-yourself install with our Turner Flash tool:

Mail-In Reflash - lower upfront cost but additional shipping charges. Minimum downtime of at least three days. We have a 24 hour turnaround on shipping the ECU back to you but factor in transit time. Expert installation of your software at our facility.
Turner Flash DIY tool - higher upfront cost but files are emailed back and forth. No downtime - you can still drive the car while we process your tune. Files are emailed back and forth - your stock file comes to us, a tuned file is returned to you. Easy install via Windows laptop using these instructions (click here).

Should you choose to mail your ECU to us, follow these specific instructions on shipping the computer (click here). We will provide you a free Next Day Air shipping label to get your ECU to us quickly - and returned just as fast. We will contact you to arrange a time to ship in your ECU to further minimize downtime.

Turner Performance Software for E9X 328i (SULEV)

MORE POWER, IMPROVED EFFICIENCY!!
Max HP gain = 15 hp
Max Trq gain = 12 ft-lbs
Rev Limit = 7000 RPM

Our software fully maximizes the N51 engine in the 328i while in SULEV spec (Super Ultra Low Emission Vehicle). The stock BMW software is hampered by settings for 87 octane fuel. By re-mapping the engine programming for 91 octane, we can make more power, torque, and improve fuel mileage - all without harm to the engine or affecting driveability. We have paid particular attention to increasing low and mid-range torque. The throttle response is also improved (quicker) eliminating unwanted and dangerous flat spots in the pedal response.

This software file is for the N51 engine SULEV model only. SULEV is a specification used in some parts of the US where emissions compliance is critical (mostly in California, the Northwest, and the Northeast). The computer and engine specs are different than the 'regular' 328i N52 engine.

There are two ways to install our software: mailing the ECU to us for a reflash or do-it-yourself install with our Turner Flash tool:

Mail-In Reflash - lower upfront cost but additional shipping charges. Minimum downtime of at least three days. We have a 24 hour turnaround on shipping the ECU back to you but factor in transit time. Expert installation of your software at our facility.

E90 325i N52 Turner Stage 2 Performance Software

330 MANIFOLD UPGRADE TUNE

Our Stage 2 software takes full advantage of the 3-stage 330 intake manifold on the N52 engine. We take our base Stage 1 software file and tune it for the improved flow coming through the 'High Output' 330 intake manifold. The 330 manifold is one of the best power enhancements you can do on the N52 engines and proper tuning is a must to get the most from it. We modify the factory maps for fuel, ignition, and camshaft timing to maximize the 330 intake manifold upgrade. Additional tuning is done to the pedal input, throttle response, and torque limiters for a better torque band and smoother power delivery. You can use the car with the 330 manifold installed and the stock software but the original software will not be optimized for the new manifold. We can also tune for Cold Air Intake (including BMW Euro intake) as well as sport exhausts.

There are two ways to install our software: mailing the ECU to us for a reflash or do-it-yourself install with our Turner Flash tool:

Mail-In Reflash - lower upfront cost but additional shipping charges. Minimum downtime of at least three days. We have a 24 hour turnaround on shipping the ECU back to you but factor in transit time. Expert installation of your software at our facility.

Should you choose to mail your ECU to us, follow these specific instructions on shipping the computer (click here). If you are unsure of how to ship your computer, we can provide you with a shipping packet and shipping label. Return shipping is by UPS Ground but Express shipping is also available.
