Package Structure

The items in an M1 Package are grouped by subsystems (eg Fuel, Ignition, Engine, Coolant). The top level of a subsystem contains the channels that summarise key properties and the primary calibration items. This means that an overview of a subsystem is contained in the items at the top of a tree view or with the shortest name.

The following are some of the most important package calibration items and which are fundamental to engine operation:

  • Engine Top Dead Centre for each cylinder
  • Engine Displacement: the engine capacity in litres
  • Engine Cylinders: the number of cylinders, usually a fixed value in a package
  • Engine Speed: the rotational speed of the engine, normally expressed in units of RPM
  • Engine Speed Reference Offset: the angle from the reference position to Top Dead Centre Cylinder 1
  • Engine Efficiency: the primary table used to calculate the volume of air that enters each cylinder and the following items that can be used as the table axis:
    • Inlet Manifold Pressure: the pressure in the manifold after the throttle
    • Throttle Position: a measure of the normalised throttle area derived from the Throttle Position Sensor
  • Engine Load: the mass of air that enters each cylinder which is calculated from Engine Efficiency, Engine Displacement, Engine Cylinders, Inlet Manifold Pressure and Inlet Manifold Temperature
  • Fuel Mixture Aim Main: the primary table that specifies the target Fuel Mixture Aim 
  • Fuel Volume: the volume of fuel to inject which is calculated from Engine Load, Fuel Mixture Aim, Fuel Stoichiometric Ratio and Fuel Density
  • Fuel Pressure Differential, the calculated pressure across the injector
  • Fuel Cylinder x Injector calibration. The individual injector calibrations are used to convert Fuel Volume into the injector Output Pulse Width. Each injector calibration is comprised of:
    • a Linearisation table which contains either:
      • the non-linear flow characteristic of the injector at low pulse widths, or
      • the injector dead time offset calculated from flow data
    • Reference Flow and Reference Pressure, which are used to calculate the actual Flow at Fuel Pressure Differential.
  • Coolant Temperature: used in fuel calculations to compensate for temperate effects during starting and engine warmup
  • Ignition Timing tables. Tables are provided to allow the desired timing to be calibrated against:
    • Inlet Manifold Pressure and Engine Speed
    • Throttle Position and Engine Speed
    • Engine Load and Engine Speed
  • Exhaust Lambda can be used to indicate the air / fuel ratio measured from the exhaust gas. This is available if a MoTeC LTC is fitted and is recommended for all fuel tuning.

M1 Tune Features for Online ECU Calibration

Monitored Channels

Important channels are monitored. If a Warning or Fault is detected this is reported in two ways:

  • a flashing red section of the M1 Tune status bar, and
  • a pop-up in the Windows taskbar notifications area

Active Warnings, Faults and general Information can be viewed by pressing F3 (or the Online -> Show Status... menu)

Telemetry data recording

All live telemetry data is recorded when an ECU is open and connected to M1 Tune. Telemetry Data display can be paused (Online -> Pause Telemetry Display) and then zoomed and scrolled for detailed analysis.

Engine Tuning Notes

  • The Fuel Mixture Aim Main table must be set to the desired fuel mixture. This is used in both the Fuel Volume calculations and all automatic corrections.
  • Fuel Closed Loop control can be enabled while tuning the engine and is integrated into calibration functions. If using Fuel Closed Loop during tuning it is recommended to:
    • Extend Fuel Closed Loop Control Trim Minimum and Maximum to allow control over a broader range. Recommend at least +/-30%.
    • Set Fuel Closed Loop Period to a conservative time to ensure stable control. Recommend at least 1.5s at low Exhaust Mass Flow
  • An Engine Efficiency Quick Lambda function is provided to automatically adjust the Engine Efficiency table. This function uses Exhaust Lambda Normalised for the adjustment to ensure Fuel Closed Loop control adjustments are included when adjusting the Engine Efficiency table.

Notes

The Options line indicates options that are associated with this. The association indicates how the option affects ordering.

  • Available: the option may be added to an order.
  • Included: the option will be added to the order, and not charged for.
  • Prerequisite: the option will be added to the order, and charged for.

The different Packages contain different tuning data.
