  1. Gear ratio Calibration & Speed Signal noise

    This is likely your problem, target wheel edge accuracy is critical with hall effect sensors.  

    G4+ had heavy hardware filtering and a hardcoded software filter, which worked ok for most, but does have a negative effect on control accuracy of synchronous functions like VVT where timing is critical.  G4X has a user selectable software based filter on DI's when used as speed inputs.  Does the filter not take care of it?

    I agree, the G4+ terminology seemed more intuitive to me and even now I still occasionally need to pause and think about it before changing a setting or whatever.  

    Thanks Adam, 

    I will test tomorrow 

    do you have advice which level i need to test?

  6. Boost Map configuration problem & Dash Link Speed signal problem

    in G4x

    Posted

    Hi All,

    I have problem on my Link ECu Plug IN G4x Subaru WRX9

    i try to setup 3 boost map by switch. i join pictures from setup

    i think setting is correct but when i activate switch, on software activate wastegate table 2 or 3 correectly> but in reality when you test on driving all stay to 0. Also strange the green cursor no jump on different table.

    i try to join movie

    2nd problem, on this car we connect Link Dash strada MXS 1.2

    i have no speed signal on dashboard by the CAN.
    Speed working on link software but nothing on dashboard
    i test all signal (speed 1, speed2 etc>>) it is same>
     
    thanks in advance

    You guys are pussies. Lol.  

    Here's mine.

    keep in mind the sensor location and exhaust volume will have a large impact on the amount of gain you can get away with and the update rate.  My sensor is right in the turbine exit so responds to changes in fueling quite quickly.

    The current software may not allow numbers as big as mine, I am running a beta version which has some updates to CLL but it should be available soon.

     

    I just have my trim limit table set to zero trim in the high-vacuum region.

    Thanks Adam

    can you explain why you setup like this?

    i really interest to understand

    thanks in advance

    Typically update rate is smaller (like 1Hz) at lower rpms and faster (like 10Hz) at higher rpms, Gain control typically has a smaller gain at smaller lambda errors and a larger gain at larger lambda errors (for my car I use 2,3,6,6,6,6 but have a play to see what suits your car)

     

    Thanks for your answer,

    i will test your setup

    before  i test also this setting

  12. G4X Problem CAN-Lambda Link setting

    in G4x

    Posted

    Hello

    today i try to connect & Configure LINK CAN Lambda to Plug iN G4X Subaru

    i follow instruction on help for setup can but some problem when i connect CAN LAmbda , i am on step for CAN Devices for find Lambda CAN

    i join pictures

    also i have error message " CAN is not supported by firmware version ..."

    i already use last version

  13. G4 X CAlibration MAP sensor 4b Omni error & Error Code 9

    error 8 & 9 area debug thing which show if a value has been set higher or lower than it's expected range, update to the latest firmware and clear fault codes. (They no longer cause a fault code in the newest release)

    That error window is because you can't calibrate a sensor that is too far out, if the sensor is more than 5kpa different from BAP then it is considered to be either faulty or set to the wrong calibration.

    Thanks Working well

  16. Link CAN Lambda Problem

    The CAN lambda uses the Bosch factory calibration resistor which is inside the connector, no need for any calibration.

    Hi Adam,

    I changed Lambda sensor and problem is fixed.

    thanks for help

    ok thanks

    i will try new sensor and keep you update

    Error 24 means the sensor pump current is outside of the expected range.  It would most likely be caused by either a bad connection on the sensor side of the CAN lambda or a failing sensor.  I would probably replace the sensor as the first step. 

    ok thanks

    i will try new sensor lambda lsu 4.9<

    how to do calibration sensor?

    Check the runtime parameter "Lambda 1 Status" and Lambda 1 Error, that will give us some clues to the problem.

  20. Link CAN Lambda Problem

    in G4+

    Posted

    Hello

    Since one week i have some trouble with my LINK CAN Lambda.

    it is very strange, during idle and running CAN running correctly and sometimes  CAN Lambda STOP to work and value is blocked to 10.1

    very strange , I check all connection and sensor.

    i not understand, can you help me?

    if i change Lambda sensor , i need to calibrate system? how to calibrate?

    thanks in advance

    regards

    No, I used to think the same - it would be easier to use MAP for the VVT load axis as then it has more relationship to your VE table and it would then be easier to account for the change in VE due to cam position.

    But, as I have been doing more VVT recently I have learnt that theory is not true and it is better to use TP for the VVT load axis.  The reason is that cam timing significantly affects the MAP, so if you have MAP as an axis on your VVT table, then in some situations you get the cam becoming unstable bouncing backwards and forwards because it is both affecting MAP and controlled by MAP.

    Hi Adam,

    Do you think same for MIVEC to keep axis TP?

    Best regards

  23. Setting Cranking ID 1700cc

    The pre-crank prime is time based so this is influenced injector size.  You could start with the values in the base map and remove about 25-50%. 

    The crank enrichment is based on a percentage of the main fuel table so this doesnt usually need changing for injector size.   

    These comments assume your fuel is petrol which is what the base map was set up for.  If you are using Ethanol then these settings are out the window and you will need to determine them on your own.

    Thanks  Adam for your advice

    correct for moment i am with petrol fuel

    regards
