  1. Yes the LEM has to run wasted as it only has 4 ignition drives.

    It will be wired much like the image but inplace of the 6 channel igniter you have 2x3 channel units.

    Igniter wiring will match image 

    For the VR sensor I would expect you will be able to find a pinout from the supplier

  2. I think on the nissan the injectors are hot fed. So will have a permanent fed to them direct from the battery.

    Generally when a drive is damaged it will short to ground but I would not then expect a back feed.

    But I do think there is drive damage that will need to be repaired. 


  3. Sounds very much like the TPS channel is either at ground or 5Vs and it is operating on the fault value of 4.99

    I would be checking the 3 wires to the TPS for any shorts or broken wires. 

    If you could also connect to the ECU and then save the MAP and post / sent it through it will also have some clues to the TPS issue.

  4. It will need to be set as solenoid. But you will have to use Aux 1 for the ISC Slave function.

    You will likely have to move the function on Aux 1 to one of the other free drives.



  5. ECU has an internal termination resistor so will not need one fitted at the ECU end. If dash has an internal termination too then no resistors will need to be added. 


  6. That disk is an unusual one and I would avoid for our system. One option could be to make one slot wider if you have a way of doing it cleanly on the stock disk.

    Or look to some of the other disk options available that are 24 and 1 (no missing slots) For the likes of the RB and SR motors. 



  7. Make sure you have run the ECCS test function to check the widest slot. I'm assuming of the slots on the inner ring one is a bit bigger than the other 5? 

    Set Test ECCS Sync to ON.  This will put the ECU into a special mode where it will automatically calculate the position of the widest slot.  Note that in this mode the ECU will disable both fuel and ignition.  Enabling this function will also initialise the ECCS Widest Slot value to 0.

    11.Open the Triggers/Limits tab of the Runtime Values window (F12 key).

    12.Crank the engine.  This will start the widest slot calculation procedure.  This procedure will take about 4 seconds.  If the procedure executes correctly, the following should be observed:

    ·The Trig 2 Signal run time value will display YES first, indicating the ECU detects a correct 4, 6 or 8 slot trigger signal.  If this value displays as NO during cranking, check sensor output and wiring.

    ·Trig 1 Signal runtime value will then display YES, indicating the ECU detects a correct 360 slot trigger signal.  If this value displays as NO during cranking, check sensor output and wiring.

    ·Finally the ECCS Sync runtime value will display YES when the process has finished.

    ·ECCS Widest Slot will change from zero to a value indicating the width of the slot (typically between 5 and 25).

    13.If after 10 seconds of cranking the ECCS Widest Slot value is still zero, an error has occurred.  Recheck all trigger wiring and test the CAS output.  If this is OK, repeat the entire procedure.

    14.If the process completed successfully, switch Test ECCS Sync to OFF.


  8. You can use aux injection control to give you effective tertiary control. However on the stock RX8 manifold the bigger issue is controlling the opening of the valves as they are not a not solenoid controlled I'm led to believe.


  9. You can still do this as on overrun you will generate more vacuum so should be in a similar place in the map (top right corner) where you can retard the timing.

    The other option would be to activate a 4D overlay table that is based of TPS and RPM as a condition (use a virtual aux)
