How does the standard Audi RS3 8V 2.5 400hp drive


Today we talk about a little super sports car that we have already tuned several times. Recently, however, we tuned a somewhat special model that also received major modifications to its exhaust system, but let's go step by step. Let's see how this RS3 drives as standard and what kind of engine it has. Let's start with the displacement. This RS3 is a 2.5 (2480cc to be exact) with an inline 5-cylinder architecture, twin overhead camshafts, multi-valve cylinder head, FSI direct gasoline injection, front intake manifold, (big) turbocharger behind the engine (this Audi has a transverse engine), intercooler, and refined electronic management to get an impressive 400hp at just under 6000rpm and 480Nm of maximum torque. The engine is connected to a 7-speed sequential transmission and permanent all-wheel drive. The top speed of this RS3 is self-limited to 250 km/h with 0-100 acceleration in just 4.1 seconds.


Chip tuning unit for increasing the power and torque of the Audi RS3 8V 2.5 400hp


As mentioned, this high-performance supercharged penta-cylinder engine uses a generous turbocharger to achieve a conspicuous performance increase. The CHIPBOX digital chip tuning unit connects easily to the engine rpm sensing sensor, air intake system sensors, and supercharger pressure control sensors without changing them. Through accurate digital signal management, also tuned in accordance with engine speed, an immediate power increase of as much as +45 horsepower and +70Nm maximum torque is achieved, all while letting the stock ECU handle all engine protection and temperature control systems.


The result in terms of performance is remarkable; the already performing RS3 becomes very aggressive with power outputs of almost 450 horsepower and maximum torque peaks of 550Nm generating impressive acceleration and recovery due in part to the excellent all-wheel drive that allows this exuberance to be exploited. The CHIPBOX chip tuning additional module works in perfect harmony with the ECU, which perfectly doses the amount of gasoline injected based on the boost pressure.

We remind you again that the assembly of the chip tuning unit does not require any mechanical or electronic modifications to the stock Audi control unit, meaning the ECU is not in any way tampered with or even reprogrammed, as is the case with ECU remapping. Remapping is an operation that leaves indelible traces and potentially results in the loss of the warranty. In this case, you get at home a kit consisting of additional electronics with high-quality automotive wiring and complete with genuine Audi connectors. Simply attach these connectors to certain points of the engine wiring following the clear and complete assembly instructions included with each kit, and the electronic tuning is complete. In a few minutes, you can increase the power and torque of your Audi RS3 2.5 400hp with values of +45hp and +70Nm.


Accelerator pedal module for the Audi RS3 8V 2.5 400hp


For the more ambitious, we also provide a second kit consisting of an electronic chip tuning module that is easily installed on the accelerator pedal position sensor. This kit is called PEDALBOOSTER and can be set to different driving modes, allowing you to further reduce the response lag of the engine, making it even more responsive and sportier. Again, this is a completely reversible electronic tuning that does not require making any changes to the stock Audi system; everything can be restored to stock conditions without leaving a trace.

Audi RS3 8V 2.5 400hp exhaust sound valve management control unit


Passionate and exacting drivers may feel the need to modify the management of the valves that control the engine sound on the RS3 exhaust system. For those who feel this need, the EVC SPORT kit is also available, allowing the rider to decide whether to leave the management of the throttle valves to the original ECU or to keep them open at all engine speeds. This chip tuning module allows the RS3 to be customized by releasing the full sound of the mighty turbocharged 5-cylinder at will, making driving even more exciting.
