• Flat foot shifting

• Configurable engine safety trips on all important parameters: oil temperature, oil pressure, Lambda, fuel pressure and crankcase pressure

• 64mb Built in data logging capacity using a market leading analysis software of over 8 hours worth of data, with logging sampling rates at up to 1kHz

• Factory turbo support and aftermarket larger turbos

• 6 Injector control with support to use any aftermarket injector
