Performance Logger

What is it?

The Squadra Tuning Performance Logger is a unique OBD tool that is completely focused on getting the maximum driving pleasure in terms of performance from the Alfa Romeo Giulia and the Stelvio.

The Performances Logger uses already existing data that is exchanged between the various control units over the CAN buses.

What can the Performance Logger do?

The core task of the Performance Logger is to continuously measure acceleration times and to save the best times. In addition, the main parameters about the condition of the engine and drivetrain are shown. The longitudinal and transverse G-forces are displayed and the highest value is also stored.

But that’s not all. Real drivers chose the “Full version” with which ALL driving assistants can be switched off. We’ve even added a special burn-out or line-lock feature. The fastest acceleration times can be set with the help of the Launch assist.

Finally, there is the option to clear error messages from all control units present.

The operation and communication

For pre-MY2020 models the operation is via the MENU button and the cruise control buttons “RES”/toggle switch on the steering wheel.

For MY2020 models there is no RES button. Instead we use the “Options” button on the right or the rotary knob. For some functions the “Lane Assist” button is used.

The Performance Logger communicates via the information line on the TFT display between the RPM meter and speedometer.

Supports both 3.5 and 7.0 inch TFT screen

Both 3.5 and 7.0 inch TFT screens are supported. The 3.5 TFT has less characters on the information line so the texts to display are different between the 3.5 and 7.0 inch TFT screen version.

Special features for Giulia en Stelvio 2.0 Turbo versions

All Giulia and Stelvio 2.0 Turbo versions are equipped with a highly effective water-cooled intercooler. To get a good understanding of the circumstances, 3 essential temperatures are displayed.

  1. The temperature of the water that cools the intercooler (WCAC)
  2. The temperature of the intake air before the intercooler (so exiting the turbo)
  3. The temperature of the intake air after the intercooler and therefore also in the intake manifold

Special features for Giulia and Stelvio JTDm versions

The amount of parameters which can be displayed depends on the JTDm version. A few special ones are mentioned here.

  1. Boost pressure and RPM of the turbo (210 hp versions only)
  2. The coolant temperature of the water-cooled intercooler (ECO and 210 bhp versions)
  3. Exhaust gas temperature (All Euro6B and Euro6D 210 bhp)
  4. DPF pollution degree
  5. AdBlue level (all Euro6D versions)
  6. Gearbox oil temperature for 8AT versions
  7. Engine coolant temperature for 6MT versions

For a complete overview we refer to the table under “Overview” a little further down on this page.

Special features for the Quadrifoglio versions

For all Quadrifoglio versions, the exhaust valves can be opened. For Giulia Q’s the front splitter can be lowered for a cleaning job.

From May 1rst 2021 the Performance Loggers for the Giulia Q pre 2020 models are upgraded. One of the new features is the calculation of the engines power and torque output. Please download the user manual to learn more about this.

Only for Q4 versions, AWD switch off or AWD torque monitoring

For Q4 versions, the driven torque can be read from the front axle. But if you want to experience the Q4 as a 100% rear wheel drive car, the front wheel drive can be switched off. This also means that burnouts can be performed.


Two versions are offered. The Performance Logger Full and the Performance Logger Light. The difference is the possibility to disable the ABS/TC and all other driving assistants, the absence of the Burnout mode and the Launch assist. Of course this is also reflected in a difference in price.

From May 1rst 2021 the Giulia Q pre MY2020 is upgraded (New). Other versions will follow later.

Is there a SGW firewall present?

From production month February 2018 all Giulia’s and Stelvio’s are equipped with the SGW firewall

When a SGW firewall is present, the Performance Logger will not work. In that case our SGW bridge can be installed.

What is the price?

Squadra Tuning OBD tool update app

With the help of this on-line app one can program the Performance Logger with a different type of  software. That can be very useful. Such as:

  • a different type of Giulia or Stelvio is purchased.
  • one buys a used Performance Logger but the exact type does not match.
  • upgrading from a Light to a Full version.
  • when one has purchased an ESC v2 and wants to upgrade it to a Performance Logger.
  • if there is a bug in the software.

Such an adjustment of the software MUST always be in consultation with us. We have to link the required software version to the serial number in question. Depending on the desire, certain costs may be associated with this.

May 1rst 2021:
Upgrade Giulia Q Full versions: Free.
Upgrade Giulia Q Light versions: 50.– Euro
