    The RPM that is shown in the log is updated every TDC event, so if some cylinders are misfiring you can see a large change in RPM from a cylinder that is working to a cylinder that is not working.  

    Hello sir, today i test again use dwell 1-2-3ms but keep same, boost going high now until 2bar but rpm keep erotic when 5100rpm ++ and im try like 6 times, on 2times random not straight  ecu show disconnected when the rpm erotic

    and if i try push pedal in stop position cars, can do revs 8k rpm normal

     

    file name ;log12 its shows disconnect when logging was keep running

    Try raising your MAP limit.  I have had a couple instances in the past with G4x, where i was getting too close to my MAP limit and it seemed like a misfire.  In these instances, there was no sign of MAP limiter activation in the logs or on the PC, yet raising the MAP limit sorted the problem.

    hello, my limit was 400kpa now the log shows only 302kpa

    I still dont see anything related to the ecu.  Inj PW, dwell, batt voltage, ign timing & VVT angle is all stable, there are no cuts or trigger errors recorded.  So it appears to be a misfire.  I would still reduce the dwell further, most of the denso COP coils dont like much more than 2.0ms.  

    hello , i see on datalog name :log1, i see the rpm going up an down start from 4900rpm, why it happen

    hello i got some issue, anybody can help me, i got the engine like off like 1sec and it back again when pedals keep accelerate, and sometimes ecu like hank when datalog was record and the rpm it cut sametimes ecu disconect on the new version g4x ver 6.20.67

    it was like the cars cant get over 1bar boost, but all the protections it show off, 

    anybody can help me?

    my cars evo ix jdm with plugin g4x evo ix

    There are a few little things in your tune that I would change such as your charge temp table but they arent going to make a massive difference.  From the shape of your fuel MAP it seems something is very wrong with fuel delivery.  Im suspicious that your injectors are giving erratic behaviour at low pulse-widths.

    It is normal to have a VE of around 50-60 at idle and ~100% at peak torque.  Your VE table has 15.5 at idle and 130-140% at peak.  

    Here's your fuel table. The big steep wall you have between -60 and -40Kpa suggests either air flow or fuel flow is greatly changing with that small increase in load.  It is difficult to imagine what would cause air flow to change that much so it is more likely a fuel problem.  Your differential fuel pressure jumps up 50Kpa in some areas so that is not great but it seems like something else is going on too.

    As a comparison, here is a fuel table from my dead stock Evo7 :

     

    sir , can you help me to get the correct data inj,

    i still used oem resistor box inj is this corect? and my firmware is that the latest?

    can you help me to setup my ecu?

    What makes you think you have a deadtime problem?  The injector deadtime is only going to change the volume of fuel that is delivered when the battery voltage changes.

    You generally dont tune accel enrichment to give a flat lambda, you tune it so the engine gives crisp response and no flat spots.  What is the actual problem?  Does the car drive bad or have bad response?

    yes i do tuned allready without CL lambda and accel enrich,

    but the response very bad, and the fuel lambda not flat if i flap throtle

    hello, i tried many ways to adjust the data original from DW they give 2 type A and B. i tried allready but cant works

    i am on LINk pnp firmware 5.6.7.3631

    i am used FUELPUMP DW 340LPH INTANK
    INJECTOR 1000CC 42M-02-1000-4
    OEM FUELPRESS
    anyone can help?

    now the cars was going with my custom deadtime and inj shortpulse, but i got problem if we push the throtle 30% or 100% it will very bad lambda, and i try to off the accel enrich and CL lambda and turn on again all the ways keep same,

     

    anyone please help
