CarBahn EVO Intelligent software adapts to various fuel octane levels seamlessly, optimizing performance without compromising safety. It retains existing safety features and adds extra protection as needed. 

Unlike most tunes available in the market, CarBahn's software maintains the integrity of safety parameters, preserving them to prevent any compromise in engine performance and longevity. Parameters such as knock control sensitivity, super knocking control sensitivity, and catalyst thermal protection are carefully tuned within your OEM software to mitigate the risk of engine and catalyst failure. In our pursuit of optimizing power delivery, we have minimized power losses to a mere 2% increase in HP when reducing these supposed power-reducing software protections. On the contrary, we have witnessed numerous instances of damaged engines resulting from the reduction of these safety parameters. Thus, it becomes apparent that gaining a marginal 2% HP advantage hardly justifies the potential risk of significant engine damage. 

Do-it-yourself Approach: 

It is essential to acknowledge the emergence of self-tuning tools in the automotive market. While these tools offer the convenience of tuning your vehicle independently, it is crucial to exercise caution. Many of these tools come equipped with pre-set programs that conveniently bypass safety limits, thus posing a substantial risk of engine damage. The art of tuning a high-output engine requires profound knowledge and experience to extract maximum power without compromising the engine's structural integrity. 

Emissions Legality: 

Let us address the topic of removing the catalyst, commonly achieved through the utilization of downpipes. Our rigorous testing regimen involved conducting consecutive dyno runs with and without the catalyst, and the observed power gain was significantly smaller than commonly touted, typically around 2%. Nevertheless, it is important to acknowledge our shared responsibility towards environmental preservation, as clean air is vital to our well-being. Furthermore, obtaining the necessary emissions certifications without a catalyst is a daunting task and, from a legal standpoint, it is considered an infringement.
