The Nissan VK50VE 2009 package is based on MoTeC's successful GPR package series and is available on MoTeC M150 ECUs. It is a versatile and adaptable platform that is configured to run the Nissan VK50 engine in the OEM configuration, which includes the Variable Valve Lift system. The package allows for easy changes to engine tuning and hardware.

The product incorporates many ancillary features commonly found on race cars, such as anti-lag, driver switches (pit switch, launch enable, boost trim, etc.), gear shift control, knock control, intercooler sprays, launch control, chassis logging (steering, suspension), gearbox coolant pumps and traction control.

Also accommodated are many of the systems found on modified road vehicles, such as air conditioning control and definable control outputs. Most ECU input and output pin allocations can be user-defined to suit individual requirements.

The product fully integrates with other MoTeC products, and provides pre-defined CAN messaging for all current display loggers/loggers, E888, VCS, GPS, ADR, BR2, PDM, and SLM.

Original Equipment (OE) CAN messaging is not supported and car specific integration is not provided.
