Key Features of the 9M OBD Flash Module

At-home ECU calibration flashing via OBD2 Automatic vehicle selection Fault code reading capability Datalogging for diagnostics and performance analysis Flash back to stock functionality Custom features tailored to customer requirements

This tool gives you control over your vehicle’s performance calibration while retaining the ability to revert to standard software when required.

Stage 1 ECU Calibration – 435hp / 435Nm

Stage 1 tuning replaces the factory ECU software with Ninemeister’s dyno-developed calibration, without requiring hardware modifications.

Stage 1 delivers:

  • Increased output to approximately 435hp and 435Nm
  • Optimised throttle response
  • Improved mid-range torque delivery
  • Enhanced top-end performance

Additional programmable features include:

  • Exhaust valve button permanently open or closed
  • 8200rpm rev limit
  • Increased static rev limiter
  • Sound symposer delete
  • Over-rev detection optimisation
  • Revised cooling system calibration for lower operating temperatures

Stage 1 is ideal for owners seeking sharper response and improved power while retaining stock hardware configuration.

You should consider Stage 1 if:

  • You want improved performance without hardware modifications
  • Your vehicle remains largely stock
  • You desire sharper throttle and stronger mid-range torque
  • You want reversible ECU tuning

Stage 2 ECU Calibration – 455hp / 455Nm

Stage 2 builds on Stage 1 software but requires supporting hardware modifications. This calibration is designed to optimise airflow and exhaust efficiency for increased output.

Stage 2 delivers:

  • Approximately 455hp and 455Nm
  • Stronger power delivery across the entire rev range
  • Increased high-RPM performance
  • Calibrated for 98 octane fuel

Required and optional hardware:

  • 9M OPF delete pipes
  • 9M performance air filters
  • Optional 9M lightweight flywheel

Additional features included:

  • Exhaust valve always open or closed option
  • 8200rpm rev limit
  • Increased static rev limiter
  • Sound symposer delete
  • Over-rev detection optimisation
  • Revised cooling strategy to run cooler

Stage 2 is tuned specifically for 98 octane Shell pump fuel and is aimed at drivers who demand maximum naturally aspirated performance from the 4.0ltr platform.

Stage 2 is recommended if:

  • You have installed 9M hardware upgrades
  • You frequently drive on track
  • You want maximum safe output from the 4.0ltr engine
  • You are building a more focused performance setup
