The Porsche 911 GTS has always been a favorite among car enthusiasts, known for its power, performance, and sleek design. So when Porsche engineers recently stated that the new hybrid 911 GTS cannot be tuned, it was seen as a challenge by the avid tuning community. While Porsche did not intend to antagonize the aftermarket industry, the engineers admitted that they were unsure of how anyone could go about tuning the car, primarily due to its unique electric turbocharger.
In most cases, turbocharged engine tunes involve modifying the turbo itself. Tuners often replace the turbocharger with a larger one and then adjust the engine control unit (ECU) accordingly. Alternatively, they may increase turbo boost by keeping the wastegates closed longer, resulting in more power. However, Porsche advises against tampering with its turbocharger.
Unlike previous versions of the 911, the new hybrid model features a single, larger turbocharger. This turbocharger incorporates a small electric motor that can spool it up even at low engine revs. The turbocharger also utilizes its internal pressure to generate up to 11 kW of energy, which is then sent back into the high-voltage battery. The battery not only powers the turbo’s electric motor at low RPM but also supplies power to the electric motor located between the engine and transmission. Additionally, an anti-lag system keeps the boost up in Sport Plus mode, ensuring maximum power is available when exiting corners.
The complexity of the 911 GTS’ hybrid system makes it challenging to modify the software that controls it. Porsche warns against attempting to tweak or replace the electric turbo, as it could interfere with the intricate balance of the hybrid system. However, it’s important to note that Porsche’s stance differs from other car brands that have previously locked their ECUs to prevent modifications.
Nissan and Chevy, for example, claimed to have software-locked their ECUs for the GT-R and C8 Corvette, respectively. However, tuners eventually found ways to crack them and develop aftermarket tunes. In contrast, Porsche has not implemented any locks on the ECU, indicating that they believe it’s not impossible for someone to figure out how to tune the hybrid 911 GTS. The only questions remaining are who will accomplish it and how long it will take.
Ultimately, the determination and ingenuity of car enthusiasts may prevail, as they have consistently proven their ability to overcome technical challenges in the past. While Porsche’s engineers caution against modifying the hybrid 911 GTS, history has shown that where there’s a will, there’s a way. As the tuning community continues to push boundaries, it’s only a matter of time before someone unlocks the full potential of this remarkable sports car.
