  1. G4 pcl opening in G4+

    in G4+

    Posted

    Hi Grant,

    I have never been able to open G4 files with G4+ or VTS with iVTS , always will receive the error about being too old etc.

    Regards

    Dave.

    Hi Guys

     

    You can only open a G4 file in G4+ software if you are online with a G4+ ECU.

    If you are offline it will not open.

    The Copy and paste will however work offline.

    So if you want to bring a G4 or V series map over on to a G4+ the only thing you need to do is be able to power up an ECU and have it live while the map loads.

     

     

     

    Hi Simon,

    thanks for answering the question properly , I should have added the detail about being online as you described.

    Bald headed aussie, I normally add all the details :)

    Regards

    Dave.

  3. trigger one error

    Posted · Edited by Dave Kriedeman

    Hi efi265,

    turn your fuel selection from sequential to off and store to the ecu.

    Carry out an injector output test and and ignition output test.

    If you are running a distributor and one coil you can only obviously test the one output.

    Once these are confirmed leave the fuel set to off and get a timing light and do a trigger calibration,m if you have spark out put.

    Check to see if the spark timing calibration offset is still correct.

    DONT FORGET TO TURN THE FUEL BACK TO SEQUENTIAL AND STORE F4 WHEN DONE.

    Regards

    Dave.

    Hi all,

    ALSO BE AWARE THAT IF YOU USE ANYTHING BUT TRADITIONAL AS YOUR FUEL EQUATION LOAD you will only have LAMBDA as the display.

    MODELLED and MODELLED- MULTI FUEL USE LAMBDA MODE ONLY.

    Regards

    Dave.

    Hi efi265,

    If you press R when connected to the laptop and go to the TRIGGERS tab and crank the engine, does it show trigger 1 NO, Trigger 2 Yes , RPM 0, or different.

    Can you bypass the ignition HOLD POWER circuit and see if the engine fires, or you get trigger 1 back.

    Regards

  7. Dual maps on G4 subaru v5

    in Link G4

    Posted

    Hi Amvegeta,

    the above screen shot shows exactly how to do this.

    Just don't use boost table 2 if you are not running boost.

    You don't use outputs you use a switching input, normally a Digital Input as per my example then you simply use the tables 1 or 2 dependant on input switch position.

    Please do not take offense in anyway from the following,

    I strongly advise seeking professional help to set things up properly for you if you do not have a very good understanding of this type of thing.

    Who is your local dealer, who did you purchase your ECU from, he should be your first point of contact.

    By all means ask away on here (FORUM) but maybe you need to make a list of everything you wish to do.

    Remember once the dual tables are setup they will also require tuning.

    Can you please give a more detailed response as to exactly what your intentions are, example low octane fuel to high octane fuel change only or is boost involved etc.

    Are secondary injectors and pumps involved etc, etc.

    Regards

    Dave.

    Hi,

    ok so to me it appears that by that diagram that the

    BROWN A , ORANGE A = MOTOR OPEN or CLOSE.

    RED B , YELLOW B       = MOTOR OPEN or CLOSE.

    The remaining are the position feed back inputs.

    So if you can apply 12 v positive  DC to the BROWN A wire

    and negative to ORANGE A this should drive the blade open or closed.

    Then do the same with RED B will be positive 12 volts and Yellow B will be negative , this will drive the blade open or closed.

    Please advise what colour combination opens the butterfly and what colour combination closes the butterfly.

    Regards

    Dave.

    Hi ,

    I would need the unit in front of me to test or a schematic diagram of the valve to work it out.

    I would imagine there will be a common positive feed to power the stepper and 2 aux controlled wires

    1 would be earth switched via the ECU to open the blade, the other would be earthed to close the blade.

    You would also have a sensor ground and an open variable resistor and a close variable resistor for control feed back.

    The power and open and close pins would just be of fixed resistance value, wouldn't change when the butterfly is opened or closed.

    The OPEN/ CLOSE feed back potentiometers would change value(resistance) when the blade is opened or closed.

    Regards

    Dave

    Hi,

    very easy to do.

    To make it simpler for me can you just put down wire colour and what it is.

    Using this format

    Starting top left to right.

    1            2

    3            4

    5            6

    1 = YELLOW/BLACK = DESCRIPTION   

    2 = RED/YELLOW  = DESCRIPTION

    3 = BLK/ORANGE?? = DESCRIPTION

    4 = BLACK            = DESCRIPTION

    5 = GREEN /BLK   = DESCRIPTION 

    6 = YELLOW          = DESCRIPTION.

    Thanks

    Regards

    Dave.

    Hi Grant,

    can you explain how you are doing this again.

    Sorry my brain isn't functioning correctly today, bit SLOOOOOOOOWWWWW.

    So have you installed the new G4+ ECU into the car,  then opened the old G4 software select the old PCL file from the G4 and press F4 to download into the new G4+.

    Regards

    Dave.

    Hi,

    OK cool it is similar to what I use anyway which is a small DBW throttle body.

    I will need to search the wiring configuration as to what wire has what function, then I can create a schematic and file for the operation of the valve for you.

    What boost control range are you wishing to work with, example 7 psi to 14 psi etc.

    Regards

    Dave.

  15. How do I disengage traction

    in G4+

    Posted

    Hi R33 GTST,

    Traction control needs to be setup in the software, and after that the Traction Control will turn on automatically every time you start the car.

    Then you must turn it off with your switch (DI) if you don't want it on.

    The TC function works like OEM setups , on automatically and requires manual override to turn off.

    Regards

    Dave.

  17. afr reading

    in ViPEC V Series

    Posted

    Hi davidbek95,

    the analogue volt input on your V88 that you have set up as WIDEBAND AFR is  the calibration set as AUTRONIC 0 - 5 VOLT.

    Also the Autronic Wideband has 2 analogue volt outputs,

    1 = 0 - 1 volt

    2 = 0 - 5 volt.

    The AFR these voltages represent must be programmed into the Autronic AFR meter.

    From memory FUNCTION 9 and 10, but not 100% on that I would have to check those FUNCTION NMBERS.

    Regards

    Dave.

     

  22. Oil pressure sensor issue!

    in Engine Tuning

    Posted

    Hi Richard,

    I am not sure how similar the TI (TEXAS INSTRUMENTS) OIL PRESSURE sensor 150 psi  calibration is compared to HONEYWELL 150 psi calibration.

    So you have 5 volts reference going to the sensor

    Sensor signal is going to an Analogue volt input

    Sensor negative is going to sensor ground NOT EARTH

    If you have terminated the sensor as above then I would be checking the calibration values.

    Regards

    Dave.

  24. Lambda to AFR

    added information

    Hi Rob,

    below I have attached a screen shot from my own personal tune I am about to do on my Skyline with onboard WIDEBAND and external wideband on my FURY,

    Are you referring to the fact that the centre of the gauge reads the words LAMBDA.

    Both my WIDEBAND / LAMBDA inputs read AFR fine.

    Note LAMBDA/AFR 1 is the onboard Lambda sensor and was not connected at the time of this shot.

    I was just starting my base fuel tune hence for the flat 40 cell numbers everywhere. :)

    Regards

    Dave.

    Hi Rob,

    just some more settings info.

    Hi Rob,

    I also forgot to reply to your question regarding your NB OXY SENSOR.

    If it is faulty bin it.

    You can leave your wideband sensor in there.

    The NB sensor or the WB sensor, will only require to be left in the exhaust if you are using CLL (CLOSED LOOP LAMBDA) control.

    Or wish to maintain AFR data, which you will require a WB to do so.

    Regards

    Dave.
