Since 1983, FVD-Brombacher has been setting the standard for Porsche® engine building and tuning in Germany. Our broad mechanical knowledge of the flat 6 Porsche® engine naturally led to our development of Engine Management software. Over the years we have perfected the art of software tuning, making substantial gains in horsepower and torque, while retaining drivability and most importantly reliability. Unlike many others in the industry, our only focus is software for Porsche®. This allows us to bring you the most polished, factory-smooth and powerful aftermarket software product for Porsche® period.

The 991 Turbo and Turbo S DME or ECU has tuning protection from the factory. So in order to deliver software that is both powerful and reliable we acquired a piggy back unit that could access and sample all of the sensors needed to handle all of the sophisticated electronics / conditional variances that the 991 Turbo and Turbo S have onboard. By monitoring and adjusting values on the intake manifold pressure sensor, boost pressure sensors, fuel rail pressure sensor, ecu (Can bus low and high) and camshaft angle sensor we can give you safe, reliable power gains.

CONVENIENT– FVD Software Module can be installed by a trusted independent shop or participating FVD dealer. It is not necessary to pull out the ECU and send it to us and you don’t have to transport your car to a tuner like the competition.

POWERFUL – The FVD Software Module modifies the ignition timing, optimizes the air /fuel ratios, increase the rev limiter and modifies the boost mapping. Our programs are custom-written for each of your vehicle’s modifications. That means that we can extract the maximum performance gains over what our competition can offer you. For all Porsche® vehicles from 2000 upwards, we also alter the throttle response which effectively negates the throttle delay found in E-Gas or drive by wire vehicles. The throttle response is improved linearly so that you don’t experience sharp increases commonly found with other software tuners who tend to exacerbate the throttle response. For us, the “Devil is in the details”, so we concentrate on laying the power down more smoothly, while providing consistent acceleration without wheel spin. Ultimately, FVD tuned cars are quicker than their overrated counterparts with the added benefit of lower tire expenses.

RELIABLE – All of the OEM engine software safety features are left fully intact and are not disabled. So you will benefit from the added performance without sacrificing the reliability that the Porsche® brand is renowned for. In addition, our software engineers have been trained by Bosch and Siemens in Germany, so you receive their factory expertise in writing software code for Porsche®. They have been writing software for Porsche® since 1983, before many of our competitors were established; very few can make that same claim. Most importantly, our software engineers are committed to software tuning for PORSCHE® ONLY, so our sole purpose is to write the most polished Porsche® software available in the industry.

REVERSIBLE – The FVD Software Module is completely reversible and once removed is undetectable for dealer service / diagnostics / extended warranty.

ADAPTABLE – Our software is adaptive and as such we give you hundreds of software timing maps. That’s right, hundreds of software maps! Each of our maps are tied into the vehicle’s sensor information so with differing variations in climate, throttle, exhaust gas temperature and octane our software automatically adjusts to give you superior performance and a factory-smooth feel. We also adjust the software to accommodate 91-100 North American ((RON+MON)/2) and Rest of World 95-104 (RON) octane automatically (adjusts timing and knock sensors accordingly). This is done automatically without the need of external hardware or toggling through the cruise control functions, just fill and go! If you want to change the intake or add a throttle body in the future, for example, our software will also adapt for larger Porsche® throttle bodies and IPD plenums with greater air mass automatically*, simply install and feel the gains without the hassle of sending the ECU back or having to install another file.

ECONOMICAL – Since our software is adaptive, we can offer un-paralleled savings over our competition and there is no additional hardware needed. Our listed software price allows you to add 200 cell catalytic converters, mufflers, headers, high flow intake, larger throttle body and intercoolers without having to pay for an updated software file. In fact, the only time you would need an updated file is if you remove the catalytic converters for racing, upgrade the turbochargers or change the internal engine components. In contrast, many of our competitors charge you for each individual hardware upgrade or charge you for performance in stages.

GUARANTEED – 30-day money back guarantee! Not satisfied with the power, simply remove the module and send it back. No questions asked.
