MoTeC's M1 GPR Drag Package is a versatile tuning platform that has been developed specifically for drag racing applications.

It is a highly adaptable solution that can be configured to control a multitude of complexities, from the simplest of engines to a multi-throttle, quad-cam, boosted engine with two injectors per cylinder, a sequential gearbox, nitrous system and many other high performance enhancements.

MoTeC's GPR Drag includes:
Included in GPR Drag are numerous ancillary features common to race cars, such as:

• Anti-lag
• Driver switches (e.g. pit switch, launch enable and boost limit)
• Gearbox control
  
• Knock control
  
• Intercooler sprays
  
• Launch control
  
• Gearbox coolant pumps
  
• Traction control

Key features for drag racing include:

• Time based trims and compensations
• Improved large turbo boost building for launch
• Traction control for vehicles with torque converters
• "Two Step" Launch
• Individual cylinder exhaust temperature fuel trim
• Suspension position with 1000Hz logging capability

The Package also caters for many systems found on modified road vehicles that may be useful in a racing context, such as air conditioning control and four definable control outputs.
