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 12 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 12 HP advantage hardly justifies the potential risk of significant engine damage.
