New Audi 3.0 TFSI now with over 400 hp
RaceChip delivers performance boost to new Audi 3.0 TFSI
The RaceChip Ultimate is now available for the latest generation of Audi’s 3.0 TFSI engines, which come from the factory with 333 hp and 440 Nm. This is leading chip tuning manufacturer RaceChip’s answer to the new SENT technology, which the Volkswagen group has now employed in some of its engines. The introduction of SENT technology heralds the digitisation of vehicles sensors. The RaceChip Ultimate with SENT technology starts at a purchase price of 1,299 euros for the Audi 3.0 TFSI models S4, S5, A6, A7, A8 and Q7 in RaceChip’s online store and from select partners.
Pure driving pleasure with the Audi S5
As their development vehicle, RaceChip engineers used the Audi S5 with its supercharged 3.0 TFSI engine. Featuring a factory power output of 333 hp and 440 Nm, the engine achieved values of 402 hp and 483 Nm in testing with the chip tuning technology of the RaceChip Ultimate. The 70 hp improvement elevates the S5 into the same performance range as Audi’s top-tier RS class. “Thanks to this new version of the RaceChip Ultimate, which has been specifically developed for these engines, the S5 drives almost like its big brother, the RS5. With the Ultimate, outstanding factory performance has turned into spectacular power”, said Alexander Zengler, Senior Expert in product development at RaceChip. “The development of auxiliary devices for engines in which sensor data is transmitted digitally is a great leap forward for us. Once can think of the decryption and optimization of these digital signals as like learning a new language.” A 20 per cent performance boost promises a driving experience with the RaceChip touch. When utilized in exactly the right way, the 3.0 TFSI’s power reserves unlock the engine’s true potential and transform the driving experience into pure pleasure. Audi is now using SENT technology in the most sophisticated configurations of the 3.0 TFSI engine in its various model series. Chip tuning market leader RaceChip offers its performance boost for these models starting at 1,299 euros. The hardware and software of the RaceChip Ultimate has been completely redesigned around this revolutionary sensor technology. Besides this new product for SENT, RaceChip offers performance chips for a variety of vehicles and engines from a starting price of 129 euros.
No interference in the original engine control unit
With the digitisation of vehicle sensors, a sensor can access several different parameters, albeit in encrypted form, at the same time. The complex decryption, optimization, encryption and transmission of data to the engine control unit must thus be carried out by the tuning box – and all that in real time. From the perspective of a chip tuner, the need to encrypt and decrypt of data in particular makes the process significantly more complex, as these steps were not necessary for analogue sensors. Yet not long after the introduction of the new sensor technology, the development team at RaceChip overcame this hurdle – the first provider of auxiliary control devices to do so. Prior to this technological breakthrough, engines equipped with SENT could only be optimized via a physical intervention in the original engine control unit (ecu), which is associated with a number of risks for the engine and for drivers. With the RaceChip Ultimate for SENT, remapping or flashing the ecu is no longer necessary. The twenty per cent performance increase is achieved by an auxiliary control box that leaves the manufacturers’ electronics untouched. RaceChip underscores its high safety standards with the Ultimate’s two-year engine warranty.
SENT is a new serial protocol for sensors that are used in the automotive industry. It stands for “Single Edge Nibble Transmission”. Whereas conventional sensors output an analogue parameter to the control unit, these new sensors are digital, feature a high resolution, are highly reliable, resistant to electromagnetic interference and are inexpensive to produce. In addition, more than one parameter, for example pressure or temperature, can be transmitted at any one time. These features mean that the SENT protocol has great advantages over older serial bus connections because more exact parameters at higher frequencies can be used for very precise motor control.
Alexander Zengler is certain that, in the future, all car manufacturers will switch to digital sensors. The new SENT sensors require less wiring and, as a result, they are lighter and less expensive for the manufacturer. “With the adaption of the Ultimate to SENT, RaceChip has responded to the digitisation of vehicle sensor technology at the right time and reaffirmed its position as the leading provider of chip tuning.”
