BMW 4 Coupe (F32, F82) M4 431 HP

The hardware of the PowerControl X is the technically most advanced additional control device on the market. The module works with the multi-map technology 4.0, which can process up to nine channels (including up to 3 digital SENT channels) in parallel. PowerControl X optimizes the parameters relevant to the fuel-air mixture and thus ensures more effective combustion. In addition to a significant increase in performance, this also leads to a reduction in specific consumption. In opposition to many competitor products, PowerControl not only has a single data set that applies to the entire rpm band, but is also able to access speed range-optimized maps through an additional reference connection. This ensures optimum performance across the entire rpm range.

Each DTE performance tuning module has three different programs which are fully adjustable¹: Sport, Dynamic and Efficiency. The driver can select a program at the simple touch of a button.

¹Deactivation required for TÜV approval.

No, after the harness and module have been removed, the vehicle is back to its original stock condition and the tuning system is not detectable. DTE’s PowerControl does not over-ride any engine protective functions and optimises all performance increases within the ECU’s standard working range, therefore no messages are logged in its memory.

Yes, an increase in performance needs to be registered, since the installation of an additional control system represents a structural change. Without entry thereof into the vehicles documents by means of partial inspections or individual inspection via a test report, may lead to the loss of insurance cover and the cancellation of the road traffic operating license.

The performance system is connected to some of the main engine sensors, which may include fuel injection, boost pressure sensors, rail pressure sensors (for diesel engines) and intake manifold pressure sensors (for petrol engines) as well as the camshaft’s connections. The relevant signals are assessed, optimised and then sent on to the engine which improves its performance.

No. As the tuning box is directly connected to the control circuitry of the vehicle there is no need of a separate power supply.

Yes, thanks to the engines improved efficiency, fuel consumption can be reduced by up to 15%. By changing gears earlier as well as more frequent driving in the lower rev range, fuel savings are most certainly possible.

Our performance enhancements are delivered ready-to-install. A detailed and illustrated step-by-step guide facilitates installation. Clearly labelled components and wiring also make things really easy. This makes the installation of the PowerControl really straight forward and, depending on the vehicles make and model, usually takes no longer than 30 minutes.

Yes. With the new PowerControl X you have the choice of whether you prefer to use the app to adjust the tuning or the classic way using the buttons.

Yes, you can switch from any DTE Systems app to one of our other apps with a quick tap on the display. Furthermore, as soon as you have registered for one of our apps, you can also use your access data for another app from DTE Systems.

The optimised performance and torque are always noticeable even without a smartphone connection. You would need a connection for i.e. changing programs.

Yes, the program selection and the fine adjustments are saved for the next drive after the power is switched off.

Yes, you can transfer your PowerControl to your new vehicle, with a quick reprogram of your existing module and possibly a harness change, and at a fraction of the cost of a new system. You can send it in for us take care of the conversion for you or visit our HQ and let us do the rest. Please note: The new engines technology should be compatible with that of the current systems.

Yes, please inform your insurance company about the vehicle’s performance changes. (Only in Europe)

An increase in performance may lead to the exclusion of warranty claims against the seller and any warranty claims against the manufacturer. You will receive a comprehensive guarantee package from DTE Systems. (Only in Europe, coming soon to Southern Africa)

Yes, the all-over epoxy resin coating of DTE’s high performance tuning PC boards ensures excellent durability and the best possible protection against moisture.

Under Engine Protect +, DTE introduces a brand new series of industry leading security standards. These continuously monitor engine signals and protect all the connected sensors which guards against ECU overload.

Yes, a major advantage of DTE’s current auxiliary control unit, is its compliance with the statutory and vehicle emission values. The engines combustion is improved in all operational areas which means that the fuel is used 100% efficiently. This also means that DTE can increase the performance of vehicles which aren’t fitted with diesel particle filters without any concerns. Compliance with the engines exhaust gas values is confirmed by the vehicle-specific parts certificate.

Yes, the protective functions of the engine management system are always maintained and the vehicle is fully diagnosable.

If a vehicle has been well maintained and serviced regularly, or even if it runs well but has high mileage, still makes it a perfect candidate for our performance enhancements.

No, as a manufacturer of performance enhancements, our focus is on the optimisation of motor vehicles, commercial vehicles, tractors and boats.

No, due to the fact that vehicle’s tax is determined by the engines displacement and its relevant pollutant class, which remain unchanged for all usual engines by the DTE’s performance systems, means that the vehicle remains in its relevant tax bracket. In case of your individual engine, please contact us.

Yes of course, DTE’s PowerControl can also be used on vehicles with automatic gearboxes, dual clutch transmissions (e.g., DSG), or semi-automatic (e.g., tiptronic).

No, DTE’s PowerControl optimizes the air & fuel ratio and not only the amount of fuel injected, but also the quantity thereof as well as the AFR’s (air to fuel ratio’s). This ensures a balanced air to fuel ratio throughout the entire RPM range as well as very low smoke emissions. Compliance with emission values are also certified within our parts certificates.

Yes, simply via the keypad, DTE’s PowerControl can be switched on & off as needed.
