In response to the shift to more complex petrol turbo applications we developed the DTUK® FSR Multichannel Tuning System, a variant of our highly popular CRD-T Tuning System benefitting from the same multimap technology and like the CRD-T we have now redeveloped the FSR system to incorporate the latest, faster microprocessor and onboard controls.

The faster microprocessor allows for a quicker signal response and smoother power delivery. The onboard controls are used both for switching between maps and for making adjustments within the map itself. Also new to the system is an OFF setting. No longer do you need to disconnect the system in order to return to standard power, you can simply switch the system off when the additional power is not needed.

Whereas our CRD-T is a two channel system, the FSR+ can control multiple channels across multiple sensors. These can include:

  • Boost Pressure Sensor,
  • Crankshaft Sensor,
  • Manifold Pressure Sensor
  • Coolant Temperature Sensors.

This system is plug and play gives you both enhanced power, smoother delivery and better fuel economy.

This system contains surface mounted electronics and an on board micro processor which we load with vehicle specific software that has been tailored to your make and model of car.

We use Original Equipment (OE) connectors which enable easy fitting in minutes, not hours meaning that the system can be removed at any time. Once the system is removed your car reverts back to factory settings, leaving no physical traces behind.

Often the system can be re-programmed to fit other applications if you change your current car.*

Three individual tuning maps written specifically for your vehicle are saved to the memory of the system prior to despatch. Every driver has their own unique style, by offering three distinct maps we provide you with the adjustability you need to ensure that the system suits both the driver and their vehicle.

This means optimal matching of all control parameters at every level of performance.
This is possible through the use of high performance processors that facilitate the detailed real-time scanning of the original software without influencing the internal protection functions of your engine.

Improved driveability as a useful extra effect.

Economy is achieved by the use of an enhanced ignition map. This releases untapped power from the engine which leads to raised levels of efficiency, which in turn leads to reduced fuel consumption. The increase in torque facilitates a performance level and driving style that requires fewer revs per minute, therefore significantly lowering levels of fuel consumption. According to driving performance, savings of fuel consumption of between 10% and 20% are possible, meaning that your tuning pays off very quickly.

Please note that while fuel savings of 5-10% are achievable with the FSR they do depend on your individual driving style and therefore cannot be guaranteed.

All DTUK Petrol Tuning systems arrive to you carefully packed, complete with everything you will need for simple and straightforward installation. This includes full colour instructions, your petrol tuning system, the correct wiring harness including OE connectors and where applicable a blanking plug should you wish to temporarily return the car to standard power without removing the loom.

These units come with full TüV approval.
