About the generation

What makes the Alfa Romeo Giulietta special

Alfa Romeo Giulietta tuning: Quadrifoglio Verde or 1.4 MultiAir

The Giulietta Quadrifoglio Verde with 240 hp and the 1.4 MultiAir with 170 hp are a long way apart in factory output, yet each has its own GAN GT figures. The hot version uses the 1.75 TBi petrol engine, named the 1.8 TBi in the catalogue, with 235 hp from 2010 and 240 hp from 2014. Because the QV engine came in two output levels, the catalogue covers both. The catalogue gives them as 235 hp and 241 hp.

In the catalogue the 150 hp MultiAir is rated at 230 Nm and the 170 hp version at 250 Nm. The base 1.4 TB without MultiAir has 120 hp and 206 Nm, and it stayed in the range until the end of production in December 2020. Your engine and its output tell you which figures apply.

The diesels and the year of your car

The 1.6 JTDM made 105 hp from 2010 and 120 hp from 2015. The 2.0 JTDM was sold with 140, 150, 170 and 175 hp, all of them different calibrations of the same engine. Each calibration belongs to certain years, so check when your car was built.

Petrol cars made up about three quarters of the Giulietta registrations in Germany, and diesels about a quarter. The 105 hp petrol 1.4 left the range with the 2016 facelift. From the 2019 model year only three engines remained: the 1.4 TB 120, the 1.6 JTDM 120 and the 2.0 JTDM 170.

Questions

Alfa Romeo Giulietta chip tuning: questions

How much more power do the Giulietta QV and the 1.4 MultiAir 170 get?

With the GAN GT the 235 hp QV reaches 299 hp and 433 Nm, and the 170 hp MultiAir 218 hp and 325 Nm. Both are turbo engines, and for them the GAN GT is rated at up to 30% more power. These are the stated gains for these engine types, not a dyno reading of your car.

Giulietta QV 235 or 240 hp: which GAN GT figures apply to mine?

The date settles it: the engine made 235 hp until 2014 and 240 hp afterwards.

Giulietta 2.0 JTDM: which of the 140, 150, 170 and 175 hp versions is mine?

Match the output to the year, because one diesel was sold with four outputs. The catalogue gives GAN GT figures for each of the four outputs.

Alfa Romeo Giulietta chiptuning: tuning box or ECU remap?

Unlike an ECU remap, which rewrites the factory software, a tuning box sits between the engine sensors and the ECU and adjusts their signals. The module comes off in about a minute, and once it is removed no traces remain. Your manufacturer's warranty is preserved: the ECU software is never changed, and the module can be removed at any time.

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.
