  1. Running out of fuel - RB26

    in G4+

    Posted · Edited by iecku

    Hey

    I am currently tuning a R33 GTR. I am using the modeled fuel model to calculate fuel on this project.

    If you look at the log i am running out of fuel above 4,5k (tip-in hasn´t been tuned yet). I think it is a bit strange, cause the inj duty is only 55% and i already hit the fuel table limit with 150.

    On the first look of the fuel tables shape i would say it is a hardware issue, but if looking on the data i would say i need to rescale the fuel table. But i haven´t found a way to do something like this. It would also make no sense, cause i thought the modeled fueling will generate a true VE map.

    Perhaps somebody has an advice for me. :-)

  10. G4+ PlugIn - CAN to PCB Pinout

    in G4+

    Posted

    Hey

    I am trying to connect an AIM MXS to a Link G4+ PlugIn via CAN/PCB Cable. I used these instruction from AIM (http://www.aim-sportline.com/download/ecu/racing/LinkG4_CANBase_102_eng.pdf), but i doesn´t work. Is there a difference in wiring to the PCB cable?

    I set transmit rate to 10Hz and format to normal. The Aim is setup with the 1mpbs settings they provide.

    Do i need to adjust anything on the streams page?

    Can i see the Aim MXS on the devices page even when there is a problem in the configuration?

  14. OS-88 Gear Shift Control

    Hey Scott

    We are doing it with a shift knob with microswitches. The electronic which comes with the OS-88 does not provide anything you could need.

    We´ve found an remote cable throttle blipper from pro-shift. Do you think we could use it with the G4+ extreme. The current it takes is 16 amps!!!

  17. RB26/30 G4+ Extreme starting issues

    in G4+

    Hey

     

    I just want to update you on this project. Hte R34 GTR RB32 GTX4202 is currently running very fine. The problem back in the days was a really bad done head job. If you have high lift ams you need to modify the heads to clear them. This job was done totally wrong. The valve lifters sometimes get stuck when the valve were closing, cause there had been some deburres and to less material to guide the lifters. We had ordered a total new head by a different engine builder and are now happy.

    Now we already had some very funny tests on the track and found some other small problems on the setup. We had extremly fluctuating rpm signals around 6500+rpm so we limited the engine at 7k. We solved it with the ross performance trigger, which is really worth every penny. Also we have problems with the ET-S (AWD Pump) controlled via the link. We get pressure on the centerdiff to close, but it wouldn´t open if the valve for ET-S has a duty 0% after it. Perhaps the return bypass is stucked. So far car is fine, we are running 1,4bar peak and 1,2bar hold on spring pressure. +1bar boost is already at 3,5k!!!! I love good twinscroll setups! :-D

     

    Just FIY!!!

    Sincerely

  18. EVO8 PlugIn Trigger or Ignition issue

    in Link G4

    Posted

    Hey guys

     

    I currently got a customers evo 8. He build this car on his own but can´t get it running, that´s why it is now on me to do this.

    I loaded the basemap for Evo 4-8 on the ecu. Under trigger settings the trigger mode is set to Evo 1-6 in the base map, so I changed it to Evo 7-9 and it runs.

    But only on two cylinders. Compression test is ok, all 4 at 9bar and all plugs are wet.

    When i test the two coils (wasted spark) i get all 4 plugs to fire. So i am currently a bit confused where the mistake is!?

    Perhaps i would do a customs coil on plug setup, but i am not sure if it will solve the problem.

    Hopefully one of you guys have an idea?

    Sincerely

    Heiko

    Hey


    Sry that i haven´t answered that question. Its the big single throttle version.

    I found the problem why it runs unstable. Cylinder #5 & #6 are not firing. The plugs are clean and the exhaust pipe is cold. Picture below is left #6 to right #1!

    a>

    For me it is a trigger problem or something similar. I run the nissan trigger calibration several times no change, as i already said that the widest slot is way bigger, than the "self diagnostic" 24° by the link!!! In ignition test mode all coils are firing!

    Should i perhaps try a different nissan cas system from an r32 or r33???

    Hey

     I´m back again. Thank you very much for your support so far. I recalibrated the trigger and made the changes to the calibration as you mentioned it. There were no sync or other errors. So i fired up the engine, but it was waaaayyyy to fat. I leaned out the master, its trim and made first adjustments to the fuel map.Not much to say, but at the end the engine runs unstable, little missfiring and it seems like one or two cylinders are missing. I once again checked camshaft timing, looked into the calibration, made injector and ignition tests. Everything is right for me. I attached the log and pcl. Perhaps you guys have an idea!

    Yours sincerely

    Once again,

    just have seen there is a new Pclink Version! :D That´s why i haven´t seen this setting! Does it mean, that the master/mastertrim doesn´t need to be touched, only for small "trims"?

    Another question is, the widest slot. In the attachment you see my trigger wheel in the R34 GTR. The widest slot is more about +28° than the link measured 24°. Could i trust what the link measured?

    Hey guys,

    thank you very much for your last replies! I have overseen the engine displacement setting. :) I´ll test and recalibrate ther trigger offset with your method, when i am back in the workshop. Cam timing should be correct, but i´ll check it once again! I also wondered that the trigger offset is that way off! Do you think the crank rpm is high enough. I just tested a original RB25 car yesterday and it seems to crank with twice the rpm!

    Your sincerely

    Hey there

    My current project won´t start. The only thing it does is missfiring!!!

    The setup is following in short:

    RB26 head, +1mm oversize valves, 272° hks cams
    RB30 block, 3.2ltr stroker
    GTX4202 turbo, Hypertune inlet manifold
    Okada Projects Coils, NGK Iridium plugs & HKS DLI
    Fuel Injector Clinic 2150cc Injectors and 3x Walbro 450lph in the surge tank
    Link G4+ Extreme

    All In- and Outputs are working just fine so far. Checked everything more than twice. I also calibrated the trigger offset, all injectors and coils are firing while cranking. The ignition angle while cranking is the same like the real i see with the stroboscopic lamp.

    So my current guess is that the crank rpm is to low (battery is fully charged), anything in the calibration is wrong (what i haven´t seen yet), the trigger reads wrong ( i know about the nissan trigger problems from other ecu´s) or anything else. I attached the last log and calibration.

    I hope anyone could help me a bit. THere a hundreds of ours in that build and i really would like to fire it up! ;)

    Your sincerely

    Heiko
