Chiptuning "Alfa Romeo Stelvio 2.0 Turbo 200 pk E6B/E6D"
In recent years FCA has increasingly opted for the downtune principle. Basically a powerful engine is developed and less potent versions are distilled from it. The Stelvio 2.0 Turbo is a fairly extreme example of this.
Basically the engine is developed for 400 Nm and 280 hp. Software adjustments bring the torque back to 330 Nm and the power to a 200 hp. In themselves, figures that can easily be dealt with. Until people has tasted the 280 hp, for which the engine is actually designed. Then people really don’t want to do less anymore.
We program different torque and power levels in the A, N and D position
N = Just between A and D position.
D = The maximum torque and power.
Alfa drivers sometimes tend to install a different exhaust. And occasionally they would like to show it to themselves or to their environment. By default that does not work so well because the revs are limited to 3500 revs. At the Stelvio on 4500 (for whatever reason … ..). We have adjusted it to the normal level of 6,000 rpm. Enjoy listening!Modified intercooler strategy (from November 1, 2020).
The 2.0T engine is equipped with a water-cooled intercooler system. In the intake manifold is a heat exchanger through which coolant is pumped. The colder this coolant is, the lower the inlet temperature will be. And the lower the inlet temperature, the more oxygen the air will contain, which directly translates into more torque and power.
However, the Alfa Romeo engineers have not done their best to make the coolant as cool as possible. By changing the strategy of the cooling water pump, the liquid cools down faster and to a lower temperature. Obviously, this requires wind. So at lower speeds there is not much to be gained from it. As soon as the speeds get a bit higher, an extra buffer is built up in the intercooler cooling system so that when the real power is used, more torque and power will be available.
Test drives have shown that the inlet temperature was about 10 degrees lower than standard. Which equates to about 3% more oxygen. In theory, that produces about 14 Nm and 9 hp more. This is NOT measurable on a rolling road due to insufficient cooling/wind.Temperature limiters
Despite the relatively small torque and power gain, we still want to protect the technology extra. 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.High inlet temperatures (measured in the intake manifold, so the air that really matters) increase the chance of pinging. From 65 degrees inlet temperature, we allow the maximum torque and power to decrease. This 65 degree is not achieved under normal circumstances. Only with a combination of warm weather and long-term full load can it occur. And then extra protection is useful.We have also done something with the water temperature limit. By default, it intervenes from 110 degrees. We find that a bit late considering the normal working temperature of around 85-88 degrees. We have lowered that to 104 degrees.RON98 fuel
The standard power is well achieved with the use of RON95 fuel. As stated, we achieve the capital gains by advancing the ignition at higher speeds. That works perfectly on good RON98 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”.Start/stop strategy.
We completely switch off the start / stop system.
Sailing/Coasting (from September 2023)
Sailing or Coasting is the phenomenon that when you release the throttle in the A position and depending on the Emission version also in the N position, the drivetrain is disconnected and the engine speed drops to idle. The car then actually rolls out with, as it were, a depressed clutch. When you accelerate, the drivetrain is reconnected and you continue driving as usual. This is experienced by our customers as an irritating strategy. The car does not brake on the engine and coupling the drivetrain causes unrest. That’s why we disable this strategy at the Massimo. This ensures that the car slows down with the engine and the unrest when accelerating is gone.
Error message “U1008 LIN bus 1” made active (from September 2023)
Unfortunately, this error message becomes more common as the car ages. The problem, however, is that the driver does not see this because the malfunction light does not come on. When reading faults with diagnostic equipment, the error is displayed. But most engineers have no idea what “LIN bus 1” refers to. In practice, this is then deleted for convenience. Too bad, because this error message has major consequences. LIN bus 1 is the communication line to the circulation pump of the water-cooled intercooler. When the fault occurs, the pump stops and the inlet temperature will rise so high that the power is regulated again. But again, as a director one is not informed. We adjust the priority status from “not important” to “important”, resulting in an illuminated fault light. This way the driver is informed and action can be taken.
The remedy for the problem is to replace the relay that switches on the intercooler pump in question.
What the 2.0 Turbo can deliver maximum in torque and power is difficult to express in exact figures. The trend is that the first series delivers the most from the factory. a lot more than what Alfa Romeo promised. In the course of production, this has moved closer to the specified capacity for unknown reasons. The transition from the 1st to the 2nd series (with or without EGR / LMM) seems to have been an important moment.The couple is still more than promised. The table below shows it. We refer to the number of nerds in the larger tables at the bottom of the page.
Optional: ZF8HP gearbox tuning
From February 2023 we are able to adapt the gearbox to our wishes. Basically, ZF8HP gearbox tuning.
We focus on shift moments in all DNA positions and eliminating inconveniences. Everything aimed for more driving fun & pleasure.
