G3/G2 ECU Firmware Update V1.3.4 (03-11-06)

  • New Features

    • Closed Loop Knock Control has been enabled.  Two 3D tables are used for Knock Control over the entire RPM and Load range.  See the Help file within PCLink for setup information.

    • Tacho scaling factor available on Auxiliary Output channels 1to 4.  This allows 8 cylinder tacho's to be used on 4 cylinder engines etc...  Good for conversions where the factory tacho requires an odd number of pulses.  IMPORTANT NOTE. This setting MUST be initialised after a firmware update to a value of 1.0 (otherwise a previously working tacho output will stop working.

  • Fixes
    • A bug existed wher dwell time would become inconsistent while cranking when an inverted ignition mode (Dwell Edge = Falling Edge) was used.  This has now been corrected.  This would effect only distributed engines running a falling dwell edge.


G3/G2 ECU Firmware Update V1.3.3 (03-11-06)

  • New Features

    • On board digital trigger decoding for Nissan ECCS.  Uses all 360 slots for high precision engine position measurement.

  • Fixes

    • Idle Speed Stepper direction control has been fixed, a problem that occurs between firmware versions 1.1.35 and 1.2.2.  This problem applies only when an idle stepper motor (not solenoid) is being controlled and could cause irregular idle control.


G3/G2 ECU Firmware Update V1.2.2 (13-09-06 0.86 Mb)

  • New Features

    • Injection Rate - The option of firing groups of injectors each 360 degrees or 720 degrees of crankshaft rotation has been added for group fire applications.  If the ECU is currently running group mode connect to PCLink and check the injection rate menu is set to 720 degreees.

    • Group N Anti-Lag - A new anit-lag mode has been added especially for Group N applications.  This mode uses a configurable cyclic idle limit to maintain a reasonable idle speed in applications where the throttle plate has been mechanically opened due to motorsport rules not allowing the addition of other idle up devices.
    •  Pyro Analog Inputs - A option has been added to allow Analog Voltage inputs to be calibrated for use with pyro blocks that have a 0-5V output.

G3/G2 ECU Firmware Update V1.2.0 (31-08-06 0.86 Mb)


  • New Features

    • Pre Crank prime fuel has been converted into a 2D Table.  It can now be triggered at key-on or when the key is moved to the Start position.  Please check the table to confirm values.  The sample.pcl file can be opened to show example values.

    • Gear Calculation is now available.  Based on a speed input through a Digital Input the ECU can calculate current gear position.  This allows boost by gear which can be implemented using a 3D table.

    • Analog Temp Channel 2 has had the General Purpose Temp option enabled.  However, it is still highly recommended to use inlet temperature correction on this channel.

    • Analog voltage channels have had the General Purpose Pressure option enabled.  The sensors used must have a linear output voltage with respect to pressure.  The default unit in kPa but can be changed to PSI from the Options -> Displayed values menu in PCLink.  This will change the units on both the runtime value and the calibration numbers.

    • The following options have been added to the switching GP (general purpose) Output auxiliary functions.

      • Gear > (greater than or equal) value
      • Gear < (less than or equal) value
      • DI (value) =  OFF.  When the DI specified in “value” is OFF the drive becomes active
      • DI (value) =  ON.  When the DI specified in “value” is ON the drive becomes active
    • Flat shifting.  The edge at which this becomes active can now be adjusted.  Use the “Active Edge” menu under Digital Inputs to set this.
    • Traction Control – Launch method 3 now has an “arming time”  value. This time must expire before launch control becomes active.  This allows Flat shift and Traction control to switch from the same Digital Input.
    • Crank Hold Time.  This will hold the crank fuel for the time specified before switching to the post start fuel.  Typical values are 1-3 seconds.

  • Fixes

    • Wide Band #2 option is now working correctly on both AN voltage channels.


G2 ECU Firmware Update V1.1.30 ( 10-05-06  0.72 Mb)


  • New Features

    • The ECU now supports a new list of trigger decoding options.
      IMPORTANT NOTE. Some options available under the PCLink trigger menu have changed position. Once the firmware upgrade is complete PCLink (V3.11) should be used to connect to the ECU to check and adjust the Trigger menu if required. The following options have been added

    1. 36-1 Crank, no sync

    2. 36-1 Crank, sync on crank

    3. 36-1 Crank, sync on cam

    4. 36-2 Crank no sync

    5. 36-2 Crank, sync on crank

    6. 36-2 Crank, sync on cam

    7. 60-1 Crank no sync

    8. 60-1 Crank, sync on crank

    9. 60-1 Crank, sync on cam

    10. Toyota 1JZ VVTi

    11. Subaru V7-9

    12. EVO 7/8

    13. MX5

    14. Mitsubishi GTO

    15. LS2


    • The EVO 1-6 decoding method has changed to incorporate both leading and trailing edges for improved resolution.
      IMPORTANT NOTE. When upgrading from older firmware versions two important things should be done.

      • 1 - Remove the ECU lid on change the setting of the Dip Switches located on the Sub board. These should now read: 

        • Dip Sw 1 = ON
        • Dip Sw 2 = OFF
        • Dip Sw 3 = ON
        • Dip Sw 4 = OFF
      • 2 - The base timing of the engine MUST be rechecked and adjusted from the “Trigger/Calibrate” menu.
  • Fixes

    • The combination of 2 teeth per TDC and the ignition mode set to distributor will cause every 2ndspark to be lost when the ignition angle moves close to a Trigger point.


G2 ECU Firmware Update V1.1.29 ( 24-04-06  0.72 Mb)


    • Fixes
      • RPM Limit: Under certain conditions when crossing from Hard cut to Soft cut the ignition would remain OFF when the engine speed falls below the RPM limit. This would cause the engine to stop.

G2 ECU Firmware Update V1.1.28 (0.72 Mb)


    • Fimrware Changes
      • If Anti-Lag is currently in use, please read this.  A full explanation of this function is available from the online help contained within PCLink.  On previous firmware versions the Anti-Lag Mode1 function uses a Digital Input selected to “Anti-lag” to control the ON or OFF state of the function.  This method has been changed. The DI channel used to control the Anti-lag should now be selected from the MotorSport/Anti-lag menu.  A menu will allow the user to select from DI 1 to DI 3.  The actual DI(under the Digital Inputs menu) should be selected to “General Purpose Input”.  What this means is multiple functions can be assigned to the same input.
      • Vehicle Speed options have been changed to read “Speed”.   The Calibration method has been changed to allow more flexibility in the method used to determine speed.  A full explanation of this function is available from the online help contained within PCLink.
    • New Features
      • Flat Shifting has been enabled.
      • Launch Control has been enabled.  Three modes of Launch Control are available including clutch switch activated and vehiclespeed referenced.
      • Soft ignition cut has been changed to cut alternating cylinders.
      • Knock Level now available for viewing and logging  under the Ignition menu.

      • All Analog Inputs can now be calibrated to accept a 0-5V signal from an external Wide Band control unit.

    • Fixes
      • The boost control solenoid is disabled at key on and during crank to avoid unnecessary operation.
