Chiptuning "Alfa Romeo Giulia 2.0 Turbo Veloce 280hp" 

Squadra-Tuning tuned here in the US,

The 2.0 Turbo MultiAir engine in the Giulia/Stelvio has been put on the market with 280 hp and 400 Nm (295 ft-lb). However, the rollingroad tests show very different values. Everything between 440 (324.5 ft-lb) and 460 (339.3 ft-lb) Nm and between 280 and 310 (!) Hp is possible. The first-produced Giulia’s were shown to have the most Hp/Tq.

Despite these major differences, the big question for us was how much extra we could extract from the motor. After a lot of research and testing, we can only say that there is not much to gain Hp wise but much more in Torque. With some turbo pressure increase in the mid speed range, about 20 to 30 Nm is added. By advancing the ignition at higher speeds around 10 to 12 hp. Increasing turbo pressure at higher revs unfortunately brings NOTHING extra, except for an increased risk of ignition problems due to too much back pressure from the catalyst.

Using the highest quality/octane fuel is a must to achieve the best performance.

That said “improvements” can be achieved in other areas.

DNA settings

The torque and power in N and D position are the same as standard. In the A-position it is considerably lower.

With our tuning program we have put the old 200 hp to 230 hp setting in the A-position. The N position is a happy medium between The A and D positions. The D-position achieves the maximum achievable performance.

Speed limiter

The Giulia is limited at top speed. At 240 km/h, 149mph. While the entire German industry limits at 250 km/h, 155mph.

Incomprehensible so we increased the limit to 270 km/h, 167.7 mph. 

EGR

The 2.0 MultiAir engine is equipped with both an external and internal EGR control. The external system is really outside the engine. Exhaust gases are drawn off at the outlet and returned to the inlet via a water cooler. EGR is never good for the technology and the flexibility of the engine. That is why we would prefer to switch it off.

So now the EGR valve does not work at all and in fact is later removed by the manufacturer from these cars. 

The same applies to the internal EGR. This is accomplished by slightly opening the MultiAir system during the exhaust stroke, controlled by the MultiAir system. For example, a small amount of exhaust gas flows into the inlet, which is sucked in again with the next intake stroke. The operation of this can also not be monitored or read on the diagnostic equipment. We have found how we can disable this in the software.

Speedlimiter when the car is stationary

Alfa drivers sometimes tend to install a different exhaust. Every now and then they would like to show off their exhaust note. By default that does not work so well because the revs are limited to 3500 revs.

We have adjusted it to the normal level of 6,000 rpm. Enjoy Sounds!

Temperature limiters

Despite the relatively small torque and power gain, we still want to protect the extra technology the vehicle is equipped with. The software offers great possibilities for this. And especially in the cold state. Depending on the oil temperature, we have limited the maximum torque and power. The full potential is only present when the oil temperature has reached 70 degrees (similar to the QV and it's race-mode on a cold engine).

High inlet temperatures (measured in the intake manifold, the air that really matters) increase the chance of pinging. From 65 degree C˚/149˚F inlet temperature, we allow the maximum torque and power to decrease. This 65 C˚˚/149˚F is not achieved under normal circumstances. but only with a combination of warm weather and long-term full load can this occur. And only then is the extra protection useful.

We have also done adjustments with the water temperature limit. By default, it intervenes from 110 degrees C˚/230˚F. We find that a bit late considering the normal working temperature of around 85-88 C˚/185-190.4˚F degrees. We have lowered that to 104 C˚/219.2˚F. 

The standard power of more than 300 hp is well achieved with the use of RON95 fuel/91 Octane Fuel. As stated, we achieve the gains by advancing the ignition at higher speeds. That works perfectly on good RON98 fuel/93 Octane Fuel. On RON95, the ignition will regulate itself again so that the power increase is not achieved. RON100 and 102 offer even better features. We do hereby prefer RON98 from brand fuel companies. For example Shell V-power (again RON98 since the beginning of 2018) or BP ultimate 98. We do not recommend RON98 fuel from a “budget pump”.

USA: 91-93+ Octane or higher from Top tier gas stations, preferred Chevron.  

Start / stop strategy

We completely switch off the start / stop system of course.

Accelerator pedal has not been adjusted, combined with the tune it is not needed. It's very balanced in all settings

On a 280 bhp tuning ST did not do anything to the throttle response. 

In a car without Race mode ST's opinion (and we completely agree) is that the throttle response is very well balanced in all settings. Squadra does not like aggressive throttle responses, the car becomes uncontrollable/jumpy/erratic. When you are driving on smaller country roads or on mountain roads it's very important that you are able to control the exact amount of torque. 

For cars with Race mode it's different. As you know when Race is activated in PROXI the engine is functioning like it's in Normal. Regardless if the DNA setting is on A, N, D or Race. However the gearbox still does see the difference between A, N, D and Race.

You should really realize that the shifting behavior from the gearbox has a very big influence on the driving experience.

After a long road trip to the Italian Alps ST decided to maintain the Normal throttle response for cars with activated Race mode. So the throttle response is like in Normal in all settings from the DNA + Race switch. That really gives the best dosable torque and power.  There is no need for throttle controllers, it's a perfectly matched with the Squadra Tune for the 2.0L You will find you have much better control. Using a throttle tuner will cause the vehicle to be less smooth, it can be jumpy and out of control as noted. That's not what we consider an upgrade.
