What makes the Audi S5 special
Audi S5 tuning and the 4.2 V8
One engine stands at the centre of Audi S5 tuning with a tuning box: the 4.2 FSI V8 of the S5 Coupé 8T, built from March 2007 to August 2011. It is a naturally aspirated V8 with direct injection, from the EA824 family. The engine makes 354 hp at 7,000 rpm and 440 Nm at 3,500 rpm, and its code is CAUA.
The car comes with quattro and either a six-speed manual or a six-speed Tiptronic. It shares its base V8 with the RS5, but in the S5 it is rated at 354 hp.
What changed after 2011
With the facelift in 2011 the V8 was dropped from the Coupé, and the S5 received a supercharged 3.0 TFSI with 333 hp and 440 Nm. The Coupé 3.0 TFSI has the engine codes CGWC and CGXC, and from 2014 CREC, while the Cabriolet and Sportback use CCBA and CAKA. The Cabriolet (2009–2017) and the Sportback (2009–2016) were built with the 3.0 TFSI from the start and never had the V8. The next generation, the F5 (2016–2024), has a 3.0 TFSI V6 with 354 hp, and from 2019 Europe also had the S5 TDI with 347 hp.
S5 names and codes
The first S5 with the 4.2 V8 is known as the B8, and the facelifted car with the 3.0 TFSI as the B8.5. Audi's own code for the Coupé is 8T3, and the B9 (F5) generation ran from 2016 to 2024. The V8 is simply known as the S5 4.2 V8, and it works with the GAN GA+.
Audi S5 chip tuning: questions
What does chip tuning with the GAN GA+ add to the naturally aspirated S5 V8?
For naturally aspirated engines the GAN GA+ is rated at up to 12% more power. On the S5 4.2 V8 it lifts output from 354 hp and 440 Nm to 382 hp and 475 Nm. Both figures are stated gains for this engine type, not a dyno reading of your car.
Is the S5 V8 the same engine as in the RS5, and why do the figures differ?
Both use the 4.2 FSI V8 of the EA824 family as their base engine. The S5 is rated at 354 hp at 7,000 rpm, so the catalogue figures apply to the S5 only.
Is the S5 from 2012 with the 3.0 TFSI the same engine?
No: the later S5 has a supercharged 3.0 TFSI V6 with 333 hp and 440 Nm. This page covers the 4.2 V8, so go by the engine and not by the S5 badge.
Tuning box or ECU remap for an Audi S5?
Unlike an ECU remap, the GAN module does not rewrite the software: it adjusts the engine sensor signals before they reach the ECU. Take the module off and no traces remain, because nothing is ever written to the ECU. It plugs into the existing connectors and takes about a minute to remove.
Is a tuning module the same as a Stage 1 tune?
Not quite. Stage 1 usually means an ECU remap without replacing any parts. The tuning module also works without replacing parts, but it does not change the ECU software: it adjusts the sensor signals, comes off in about a minute, and the OFF button in the app restores the factory settings.
