  2. vipec 7 bar map sensor issues

    in ViPEC V Series

    Posted

    Hi,

    it is very unlikely the ECU itself has an issue, as it has all been fine until you setup the 7 BAR sensor.

    Cleaning spark plugs is very HIT and MISS unless using a fine glass shot blaster.

    You are best removing and replacing the plugs with new ones.

    Are there any vacuum hoses left off anywhere from swapping MAP sensors etc.

    Fitting higher pressure MAP sensors will have no effect on the idle tune as long as the MAP sensor is calibrated.

    You should not have to change the idle mixtures or anything because the MAP/BAP should not  have changed unless you moved to Mt Everest or something.

    There is the possibility that the 7 BAR MAP sensor May have an issue.

    The most common fault with external MAP sensors being fitted is people wire them to 12 volts instead of the 5 volt reference they need to run on.

    Regards

    Dave.

    Hi lostsoul,

    Just to clear things up here, in your opening question you state you have a Z32 300 ZX but you also state you are using a G4 GTS/GTR PLUG IN.

    So I am a bit confused which isn't hard these days.

    The 12 volt supply is ok.

    There is no 8V trigger supply on the PNP.

    Steve is correct the GT 101 has 3 wires ,

    black with red stripe = ignition power

    Black with white stripe = Trigger  1

    Black = sensor ground = ECU pin 30

    How have you setup your triggers.

    TRIGGER SETUP SHOULD BE SET TO MULTI TOOTH MISSING.

    Trigger 1 setting should be set as

    HALL EFFECT

    FILTER 1

    TRIGGER EDGE FALLING

    PULL UP ON

    MULTI TOOTH POSITION = CRANK

    TOOTH COUNT = 24

    MISSING TEETH = 1

    TRIGGER 2

    OPTICAL / HALL

    FILTER = 1

    PULL UP = ON

    TRIGGER EDGE = FALLING

    SYNC MODE = CAM PULSE 1

    Make sure the GT 101 has an air gap of approx. 0.040' or 1 mm.

    You will need to turn the fuel off or disconnect the injectors so the engine doesn't try to start.

    I never use the timing loop at the rear of the ignition loom, I always fit a HT plug lead from the coil to number 1 plug for the most accurate timing setup.

    You need to activate CALIBRATE TRIGGERS,

    Set the timing to 15 degrees, as this is standard timing, but use any value you wish.

    Adjust the TRIGGER OFFSET UNTIL YOU MATCH THE TARGET TIMING VALUE.

    You will then need to hit the F12 Key to bring up RUN TIME VALUES

    Watch the TRIGGER / LIMITS TAB  and check it says

    TRIGGER 1 YES (GREEN)

    TRIGGER 2 YES (GREEN)

    And you have a valid rpm signal.

    As stated you do not want the the trigger 1 and 2 edges to occur at the same time.

    Regards

    Dave.

    Hi,

    so you deselected AN VLT 2 and reselected AN VLT 1 Internal MAP sensor but it will not recalibrate correct.

    There is a chance your ecu may have a 4 bar MAP sensor fitted.

    Please select 4 BAR and try to calibrate .

    Let me know how you go.

    Remember if the tune is not correct and cold start fuel etc is very rich the MAP sensor reading with the engine running will be low adding more fuel due to low MAP and also fouled plugs from over fueling from MAP issues will do the same thing.

    Regards

    Dave.

     

  7. Highlighting multiple cells at once

    Hi again,

    what DOLFO has stated is correct as per my attached screen shot.

    I have misunderstood, I thought you where requesting what I have where we will have the ability to actually highlight sections of the surface graph and increase/decrease the selected areas.

    This will also make smoothing maps out very quick.

    Regards

    Dave.

    Hi Bram.

    I love the FURY for 4 and 6 cylinder installations.

    Having a direct onboard wideband does have advantages.

    The ECU monitors the wideband at all times for errors.

    If using a standalone unit , one must assume the WB SENSOR is ok.

    With the FURY if there is a fault it will show up in the run time values.

    You are correct the FURY does use the LSU 4.9 sensors.

    Regards

    Dave.

    Hi Mark,

    do you have any PC LINK software installed on you laptop at all.

    If not then you should be able to load 4.10.2  straight up.

    I am unsure if the older software is compatible, I know all the latest versions work.

    Regards

    Dave

    Hi lostsoul,

    the error you have AN T1 = Analogue temp 1 which is either your air temp sensor or coolant temp sensor.

    The GT 101i have used many as crank triggers without issues.

    What ECU are you using, the GT 101 will handle 12 volts but really should be powered via 8 volt trigger supply, which is normally PIN A6.

    Regards

    Dave.

    Hi turbodailydan,

    I have never had an issue like this before.

    So when you change back to internal MAP and connect the MAP sensor hose to it, you are deselecting AN VLT 2 and only have 1 MAP sensor selected.

    Then you try to do a MAP sensor CAL with AN VLT  1 internal MAP and it wont calibrate , correct.

    Can you show us a picture of the sensor please.

    Regards

    Dave.

    Hi Ducie 54,

    I fly to Brisbane this week on Wednesday for major surgery so it might have to wait a few weeks if you want it tested on the simulator mate.

    Shouldn't that divider circuit be on the Fuel Pump positive side.

    Regards

    Dave.

    Hi Bram,

    my advice would be to go onto the LINK website and go to products.

    Select the standalone ECU's.

    Look at all the features of the EXTREME and compare to the FURY.

    The Extreme has more inputs etc.

    Without us really knowing what your setup consists of it is hard to advise.

    Regards

    Dave.

    Hi Mark,

    sorry no I have no ideas.

    But why are you loading such an old firmware version.

    You may have to step up in firmware versions gradually and load all the way to the current 4.10.2

    Then upgrade the ECU's, a lot of changes since that version was around.

    Regards

    Dave.

  19. Highlighting multiple cells at once

    Hi turbodailydan,

    are you referring to like clicking on the surface map and lifting a section to enrichen or lean it out.

    Or are you referring to being able to select different cells over the fuel main table for example and increasing or decreasing the chosen cells by desired value.

    Or are you referring to holding the shift key down and using your arrows to high light multiple cells and adjusting them.

    Regards

    Dave.

    FORGOT STUFF HA HA

    Hi Keith,

    You can actually use  BAP or MAP and span the Y axis of the FUEL MAIN TABLE with TPS.

    Set the TARGET AFR table by TPS or MAP.

    Normally once running above idle the MAP signal is a lot smoother unless running massive camshafts also.

    So if the MAP signal is still weak or erratic then use TPS as the Y axis on the target table.

    However I personally have never been able to not use MAP on the TARGET AFR TABLE.

    Idle areas and light throttle cruise can be an issue but you just manually tune them to suit.

    Full OPEN LOOP TUNING must be completed really before switching to full CLL control.

    Also make sure you have OPEN LOOP AFR TABLE - ON.

    The OPEN LOOP AFR OVERLAY TABLE CAN STAY OFF, HOWEVER you should tune with OPEN LOOP AFR TABLE -ON.

    Once you have tuned the OPEN LOOP FUEL then you will find that the CLL tuning will be a lot more accurate and stable,

    If using Mixture Map tuning it can be setup to use anything you like as the LOAD SOURCE.

    Be careful tuning with mixture Map unless you add filters to lock out rapid throttle position changes , decal changes etc, any transient type influences to the fuel data.

    I personally would have load source as MAP, FUEL MAIN Y AXIS as  TPS MAIN, TARGET AFR TABLE set as MAP.

    Tune FULL OPEN LOOP and then use Quick tune or MATHS KEY TUNE from data logs.

    Upgrade to firmware 4.10.2

    While you are in the fuel table you can be locked on a cell press the M key and a table will open for that sight , type in the actual AFR and the ECU will change the value of the fuel cell to the correct value.

    Also use less resolution, rpm every 500 and TPS every 10%, let the ECU do the work of interpolating between the cells.

    When you have picky areas add more resolution to those spots by adding more refined cells.

    Once you are happy with OPEN LOOP TUNING, then try your luck at CLL.

    Remember CLL is really designed to keep the mixtures around stoich for economy and emissions.

    By the way you can not use G4+ or iVTS on G4 or V series ECU's.

    Regards

    Dave.

     

  23. different settings on same ign4 output

    in Link G4

    Posted · Edited by Dave Kriedeman
    WORKING ON PCL

    Hi Neil,

    sorry but due to misunderstanding your request I have answered you incorrectly at the start.

    I can definitely change the state of IGN O/P 4 in as many ways as you wish to a degree.

    However changing the state of the actual outputs via ECU control is not possible because the Aux O/P you are controlling are not controlled via the ECU .

    The IC SPARAY and WATER INJECTION are controlled via the switch position and the condition of IGN O/P 4 being ON or OFF dependant on the switching commands.

    I could definitely configure what I THINK you want easily if the IC SPRAY and WATER INJECTION are controlled via the ECU through Aux O/P's.

    My understanding is dependant on the DI 1's state ON/OFF , you wish to control the IC SPRAY or WATER INJECTION with IGN O/P 4 ON/OFF state to control the devices, basically automate the process and have the switch as a mechanical over ride.

    Is this correct.

    There are a couple of us a bit confused on what you actually want.

    If I have explained this as you wish it to function I CAN make it work but both AUX must be controlled via AUX O/P's

    Regards

    Dave.

    Hi Keith,

    what ECU are you using, G4 or G4 + based.

    Are you tuning the engine on the road or a dyno.

    What do you have the fuel setting set up as, BAP MAP XOVER with TPS Y AXIS main fuel table and TARGET AFR table MAP as Y axis.

    Some more info on precisely your software settings, what FW are you using etc, please.

    Regards

    Dave.
