GPRP Drag

Tailor made for Drag

MoTeC’s GPR Trawl Package builds on the GPR Package, with additional features and improvements specifically for trawl applications, including:

• Additional vehicle speed and run time conditions at auxiliary outputs
• Auxiliary outlet fuel and ignition trims
• Boost Servo System – Use a servo motor to control a wastegate or use an additional throttle servo to bleed boost air from the compressor. This can help with compressor surge, act as a wastegate, or control boost with greater response.
• Clutch position limit for launch condition – can be upgraded with a switch, for drag vehicles with clutch and critical 'bite' position.
• Improved tuning resolution for highly tuned engines
• Improved sensor and calculation resolution critical for drag racing
• Individual cylinder fuel trim for respective exhaust temperature
• Warnings with engine speed and throttle limits for primary and secondary injector duty cycle
• Support automatic transmission gear detection and converter slip monitoring
• Gear output shaft speed, fuel and ignition trims, plus acceleration and thrust limits.
• Closed loop Control of engine torque by altering ignition timing. Used for traction control and launch control. By varying ignition timing rather than cutting ignition events, turbo lag in large turbos is reduced.
• Improved launch control for more vehicle configurations – faster boost build, multi-step staging, nitrous integration, and traction control integration.
• Improved Nitro Control – bottle pressure warning and additional conditions for use during launch control and time after launch.
• Improved Race Time triggering strategy – more configurable, false start detection and reset, and integration with traction control for acceleration limitation.
• Enhanced traction control using ignition timing control. Limitation based on wheel speed or engine speed for use with automatic transmissions.
• Shift light output
• Additional sensor inputs:
  • Sleep position x 4, recording at 1000Hz (with optional level 3 recording)
  • Transmission temperature x 2
  • Transmission pressure x 2
  • Tire pressure x 4
  • Tire temperature x 4
  • Wheelie bar pressure x 2
• Transmission brake control with enhanced 'bump' functionality (pulse or PWM modes) for perfect vehicle preparation.
• Fuel and ignition based on vehicle speed and throttle limit.
• Calculation of vehicle speed estimation using wheel speeds, GPS speed and time-based speed after launch. Different estimation modes for various vehicle configurations.
• Dump valve pressure control by dual CO2 style solenoids and pressure feedback
• Live adjustment for tire growth with speed
