🛠️ Software Features & Enhancements
Hybrid Integration: We recalibrate the torque request maps to ensure the gas engine and electric motor work in perfect harmony, delivering smoother, more aggressive power delivery.
Optimized Boost Management: We refine the wastegate duty cycles of the B38's turbocharger to provide a wider power band, reducing the "drop-off" at higher RPMs.
Throttle Mapping: Sharper response in Sport Mode while maintaining the smooth, efficient characteristics of eDrive and Comfort modes.
Exhaust Dynamics: Enhanced "burbles" and exhaust notes are available for the B38 engine to give the i8 an aggressive sound that matches its supercar looks.
