    Misfire issues?

    it is pretty rough there, but if you zoom in to look at the actual events on the MAP line you can see the PWs look pretty consistent. I dont think its really a fuel issue because I have ran it richer and leaner with no help in the occurrence. even across a few events like this you can see the PWs look pretty smooth. the spikes are there, but i think those are from the mysterious events that cause the MAP jump which makes it want to dump fuel as if it was really seeing that MAP

    Misfire issues?

    Hey everyone! I'm having some issues with what I think is my Link G4+ tune. I am getting an odd occurrence at about 3500rpm and about 15MAP. It almost feels like a misfire and makes a pop that sounds like a backfire through the intake. I have checked plug gap to be .028, no boost leaks, when I installed the cams and redid the timing belt I did verify timing was correct but as I am writing this I guess it could have jumped? I will check that tomorrow. I have played with ignition timing, fueling, AVCS and dwell with no luck. The problem stays on e85 as well as 91oct and 93oct. Sometimes it pops really bad and sometimes it is more mild, but it seems like a tune issue because after 4000rpm it drives completely normal. Any ideas? Build info: V9 EJ207, 266/268 Brian Crower cams, Borg Warner S200SXE (7670) IAT in the manifold plenum, Link G4+ PNP ECU, factory fuel rails, ID1300 injectors, Factory FPR, Walbro 255, Hybrid MBC/EBCS boost control, GM ethanol content sensor. That should be all the pertinent info. This map is tweaked off the factory V9 Link basemap to get me by; it definitely needs work but I wanted to figure out this issue before I got too far with everything else. Thanks for any help! I included a log/map for you all, let me know if you need anything else. flat 2.llg 91oct1.6dwell.pclr

    Laggy PCLink software

    Just kidding! I got it! I rolled back to the 2013 Intel graphics card driver and now it works! It must be a new Intel graphics driver issue :/

    Laggy PCLink software

    Hey everyone, I rolled the laptop back to Windows 7 and I still have the slow data issues has anyone figured this out? I just don't understand why my dell on windows 7 has issues but my MacBook on windows 7 is just fine

    Air temp sensor location

    Oh man, that's very cool! That's an spendy little sensor, but I like the experiment you're going to do! Any idea when you're going to get around to doing that? I would certainly like to see the results!

    Air temp sensor location

    Hey everyone! I've got a Link G4+ plug-and-play ECU on my version 9 STI and I'm looking to put an air temp sensor in the manifold so that my ECU can compensate for the cooler air temps my water injection will bring. I have a Bosch open element sensor that I would like to use and I'm uncertain of placement. I'm thinking that I would either like to put it in the floor of the plenum sticking straight up so that air flows across it coming out of the throttle body, but I need to make sure that I have space underneath the manifold for me to put the sensor there. I would also need to have a bung welded on for that location which will cut down my clearance a little bit as well. My alternate location is in one of the runners which seems like it would always have good airflow across it and it's closer to the port so it should be a more accurate air temperature. However, I'm worried that it might cause turbulence which may affect fueling to that cylinder. Do you guys have any thoughts or comments? I don't daily drive the car but I would like to have the ability to if needed, so I would like to avoid difficult heat soaked hot starts, which I do think the plastic sensor will help cut down on versus the metal GM sensor. I have included pictures have both my proposed locations https://drive.google.com/file/d/1pQMTF77ts3Lf9lIoy9a4Jie4tHulovN5/view?usp=drivesdk[/img] https://drive.google.com/file/d/1opsO1nXJpXZ7-jxnvbgBy-jlz_Osoip5/view?usp=drivesdk[/img] I'm open to any input! Thanks!

    Laggy PCLink software

    I tried the rolled back driver and it helped a little bit. Its still not as good on my Dell windows 10 machine vs on my Macbook windows 7 though :( I did try the basic layout on the current driver and it might actually be worse. At this point I'm considering going back to windows 7 on the Dell to see if that "fixes" my problem.

    Laggy PCLink software

    I do have the drop-down set to 625k and no slow connection checked The Dell laptop says "Intel(R) HD" under the display adapters tab. It says the driver is up to date. Maybe I should roll it back? I also found this for it's info if this helps

    Laggy PCLink software

    Hello all, I've been using my older Dell Inspiron N5010 laptop for tuning for the last couple years. Last week I went to do some tuning on my PnP Link G4+ and the data was lagging pretty badly. I hadn't changed any of the settings both on the laptop or the ECU. Long story short, I ended up reimaging the computer with Windows 10 (same OS I was running previously) and I still have the lagging problem. I plugged in my MacBook with Windows 7 on bootcamp and it seems to be perfectly fine. I will attach videos, but the issue is that when I blip the throttle the tracer in the fuel tab doesn't even respond by the time the engine is revving down. Sometimes not at all. Any ideas what it could be? I have tried: Reimage, reboot, uninstall/reinstall PCLink, different USB port The Dell on W10: https://drive.google.com/file/d/1uJ6uPC5fRxdk5PdSa6tk23mD8fF4vxGf/view?usp=drivesdk MacBook on W7: https://drive.google.com/file/d/1J6eYJTRGcO8G-ZgWNFDk30XiaJCK0v4R/view?usp=drivesdk

    Link G4+ and big injectors

    Perfect! Thanks Adam! I will only buy Injector Dynamics injectors, thats why I limited myself to the 1300/1700/2000s If the 1700s will idle ok, I think I will go with those. I don't think I will be running out of fuel with those any time soon

    Link G4+ and big injectors

    Hello everyone, I'm running a Link G4+ plug and play ECU in my EJ207 powered WRX and I'm going with a rotated 7670 Borg Warner and flex fuel. I currently have ID1000 injectors on flex fuel and know I will max these out before i hit my goal, so I am looking for a bigger set of injectors. Guys running the factory Subaru ECU seem to have issues with larger injectors because the ECU doesn't handle the low PW required to idle 91oct very well. Seeing that I am running flex fuel, I will occasionally be running 91oct when I cant find e85, so I am curious about how well the Link ECU does with low pulse-widths idling 91oct. I plan to aim for about 450-500WHP on e85, so I'm leaning toward the ID1700/ID2000 but if drive-ability on 91oct will be poor, I can consider the ID1300 and see about running higher fuel pressure? I can also see about running a higher idle speed for 91oct if that will make or break a larger injector set. I appreciate any insight! Thanks!

    Troubles with Modeled fuel strategy

    I have not yet got this sorted out. I did rough-in the map to 10psi and 8000rpm and see values start is 70 (idle) up to 120 (peak torque) and down to just under 100 at redline. I am running a rather small turbo, could this be boosting my airflow at low rpm enough to bump up the VE of the engine at idle?

    Troubles with Modeled fuel strategy

    Any idea where the parameter for fuel temp for injector flow is? Spent a while last night trying to find it and I could only find the inputs for fuel density and cooling coefficient. You'd think the hotter the fuel is, the more it will flow? So I should see slightly less for injector size at the "regular" fuel temp test? I just don't want to "work around" to get them to flow correctly, it makes me feel like something else is wrong

    Troubles with Modeled fuel strategy

    Alright! I checked my fuel pressure and I was correct at 43.5psi base and mid-high 30's at idle. Is there any other reason I might have such high VE values with everything else in the injector info entered correctly? I am using the factory 3-bar Version 9 STi map sensor, and I did calibrate it and I do think it saw relatively reasonable values at idle.

    Troubles with Modeled fuel strategy

    Adam, that does make sense, just to verify, I can turn off IAT in the IAT fuel correction tab and select off? Or should I just zero out the fuel trim table? In the future i do plan to run water injection, is that something to consider using the IAT table for? Or will the ecu still do just fine with the charge temp table still? Again, thanks for the help!
