    PC Link New Layouts

    Hi All, The default layouts in the current G4+ PC Link are pretty dated, I recently done a couple of new ones that will be included as the defaults in the next PC Link update. But in the meantime here they are so you can use them now. FYI, if you use both G4+ and G4X ecus and you have highly customised layouts, you can copy the same layout into both PC Link versions by just changing the file extension. G4+ extension is .llg and G4X uses .llgx. Feel free to add to this post if you have any layouts you want to share. 1366 x 768.llf 1920 x1080.llf

  2. Thats not a nice way how you say that. On every product you buy the updates stops someday and you have to invest in the new generation unit if you want get all the recent features. Besides I'm 100% sure you would have been in the same situation with the other ECU manufacturer. And if your fuel table is properly tuned, there is no need for long term fuel trims. I recommend to use Mixture Map.

    Water Pump PWM

    Hello, Did some testing, results are below. Pump: Any pump CWA50, CWA200 or CWA400 would work with these settings. We use CWA200. Wiring: 1 - wired 12V from the PMU16, 25A channel. 2 - wired Aux high state signal. 3 - wired to ecu signal gnd. 4 - simple chassis GND. ECU settings: 50% on cranking is for waking up the pump. After that, You can use higher values then 50%. If your idle is lower then 1000 RPM, adjust the PWM table axis and values to suit your application. Results: Our race car working temperature is 70

  6. The pressure compensation is non-linear and applied to the pump current before conversion to lambda (also non-linear) so it is a fairly complex relationship, generally done with look up tables. I suspect that RBR calulator linked above uses some simplified equation as it seems to give very optimistic results for the NTK sensor. They are typically about 4 x more sensitive to pressure than the LSU4.9 in my experience. For the LSU4.9 there are a few slight variations of the pressure compensation curve but this is the one that is generally used from what I have seen: So a couple

  7. I get that Link are a relatively small company, with limited resources. I'm not expecting large features to be back-ported, but there are a number of longstanding known bugs and issues with the G4+ range (cruise active light, as one simple example that directly affects me), and we feel abandoned, because there's something new and shiny, and existing features on our product aren't working properly. I'm intrigued to see the new advances coming in the G4x range, and I might be tempted to upgrade in the future, but I'm currently wary about upgrading and having another issue that's

  8. Hi all, I just wanted to congratulate the team at LINK on a truly stunning upgrade to their WEBSITE. The colours and the layout etc really catch the eye. Very pleasant to scan through the pages. The format is very well laid out. Also not just the WEBSITE, but the company and products in general. I have been with LINK as a user and dealer since the conception of ViPEC and it has been sure great to be part of and also a witness to the transformation and growth of an already great product and company to a world leader in the Electronic Fuel Injection Industry.

  10. So this afternoon I sat at the simulator and started mucking about with a few ideas. I wanted to calculate my average speed based on some event, I used a digital input latching on. In the UK we have average speed camera zones, you get snapped at the start and end and they do a distance over time calculation. Often you'll get slowed down by a Karen in an X5 not paying attention, I've always been curious how much I could safely speed up again to catch back up to 50 mph average over the trip. You can do this in log analysis with the statistics view, but this is obviously operating at run

    G4x Base map

    As a feature request can we have the option on which Lambda sensor is used for CLL. As example I'm using 5 lambda sensors. One in the turbo dump pipe and 4 in the turbo manifold using a CAN module. The software uses a average for CLL but would be nice to use Lambda one so manifold pressure is not an influence. Currently to get around this from happening I've set the 4 CAN lambdas as CAN TC.

    Personally I think Adam and the team does a wonderful job of helping people get their shittas running. In fact I've seen a number of times Adam (sorry to single you out) has gone above and beyond to help. You have to remember that these guys (non gender version) make and support the ECU. Getting the engine and systems working with the ECU comes down to who is putting in the numbers into the ECU. It's not on Link to get it running and tuned for you. Some people keep bring up this whole thing about them feel abandoned on G4+. It's EOL, new version now with better features and faster C

  20. There are definitely plans in the future to investigate other comms options for the next generation of ecu's, but with G4X we have stuck with USB so that PC Link didnt need a complete re-write as well (Months, if not years of work for our small team). The comms chipset that is in the G4X is capable of native high speed USB 2.0 as well - not only the virtual com port system that is being used at present so in theory it has the potential to be very fast. I believe this is being worked on. Ethernet is nice and robust, resilient to noise and makes wireless easy, but it has some significant n

    IS300 can issues

    Hi, I have a IS300 myself, although not running the xcessive/panicwire pnp kit, I repinned my loom to the right headers to suit. I don't have any issues.. It sounds like to me that the MPX isn't wired correctly on your loom and/or not going to where it suppose to go. Since you are using the IS300 2JZ loom, and using the panicwire patch loom, Check out pins E-5 (MPX1) and E-12 (MPX2) on the Link/Altezza header side loom, , make sure they are connected to the body loom and goto the body computer. On the IS300 loom side they "should" be connected to E4-21 (MPX1) E4-20 (MPX2). I'd unplug the

  22. Would it be possible to have an option for the the mixture map function to take into account correction made from closed loop lamda? I like the idea of having CLL running as an added safety margin when road tuning and it would be good if the mixture map could look at what corrections are are being made to make permanent changes to the fuel map.

    PC Link New Layouts

    Thanks Adam! The 1920x1080 one looks great on my XPS13 (3200x1800) running at 150% display scaling, just a few unused pixels at the bottom of the page. That does mean I can drop everything down a little and expand the table areas so I hopefully won't need to scroll! New G4+ PCLink version... ooh does that mean a few of the wishlist items & outstanding bugs might be included? I understand your primary focus is the G4X range, but please don't forget us G4+ people too quickly!

  27. The ground wires on the Link looms are 18awg, 120°C rated, so will handle about 15A each. Obviously my 60A example was stating the worst case example so that you or anyone else that reads this post in future has good information to base their decisions on. It would be very rare in real life to ever have a scenario where every output is running at 100% DC all at the same time but with power wiring it is important to consider what you have connected, the maximum DC/loads, the wire lengths, the insulation temperature rating and the amount of voltage drop that you consider is acceptable.

  28. Something I've done recently is add a knock warning to my CE Light, I used a math block to calculate knock level - threshold and put it through a gp output to get an off delay (hold time) and fed it into the CE Light Aux. So far I've only used it for playing around with setting up my thresholds (so I can see how often it happens and for a clearer picture of when it happens) but I imagine it will be very useful once I've finished setting u the knock too. It has also been very useful for reviewing Knock stuff in PCLink logs as often the knock stuff happens too fast to be caught by PCLink bu

    Cranking time

    For the subaru example the Link ECU may take up to 720deg to sync, the factory ECU may have done something more sophisticated with the extra missing teeth which would allow it to sync in wasted spark mode within 180deg. For the honda with no missing teeth the link should sync within the same amount of time as the factory ecu as there are no special tricks they can do with that basic trigger pattern. So for the honda, most likely a tune issue, for the subaru it will possibly never be as good as the factory startup.

    Cranking time

    Add pre prime fuel or increase it. Try lowering your injector timing table values, and make sure fuel rail volume does not drain back to the tank as it will take longer to build fuel pressure.

    Forget about the CanID you really need to think about Frame ID instead. Your frame ID takes up one of the bytes in the message. So in this example below, it is Frame number 13 . When this can frame is received by your teensy, you need to look a that first byte to tell you which frame it is. If the number is 13, then you know that your values in the frame are Inj timing, Ign Angle, and Inlet / LH target. So you can update those values.

  34. All flex fuel sensors do that. The signal is a PWM, the Ethanol % is the frequency and the temp is DC or pulse width. You just set the DI to "ethanol sensor" and both Ethanol % and temp will be available in the ECU.

  36. I have a couple of customers with the 1.8 VVT engine, they run great on the LinkG4+ wiring ecu. And they upgrade from the MS ECU actually, one of them because of a faulty regulator on the alternator. Without warning the alternator start to make spikes of voltage, and burn the MS ecu... We wire in the Link (without knowing about the problem), after just a few seconds of the first start, the engine shutdown. Looking at the log, we saw voltage of over 18V, the ecu cut the fuel and save everything, the ecu never burn like the MS. I have work with MS ecu, and have customers with them on, I really d

I initially thought it was something to do with my post start but didnt make complete sense as the car was out of Post Start. Then checked Warm-Up Enrichment. This was my next logical progression as the car might be looking for a little fuel adjustment? so I copied my values from th

  38. I don't have any experience with that particular motor but you should just need to connect your trigger 1 to the crank sensor (I assume the 1.8vvt motor has a crank trigger unlike the earlier 1.6 with cam sensors only) and trigger 2 to your cam sensor. Connect an aux (one of aux1-10, aux ign5-8 or aux inj5-8) and a switched power wire to the vvt solenoid. That should be all you need to do specifically for the vvt wiring. You might have to add wires to the loom for inj3&4 to run sequential fuel as they are connected to the ECU header but the earlier vehicles don't use them and so might

  43. The GM sensor uses the same calibration as the link sensor so you dont need to change anything. If you are still getting a t2 @ 5V error that means the ecu is not seeing any sensor connected (open circuit). It could be a bad connection or dead sensor. You can confirm the sensor is good with a multimeter, it should measure around 3000-3500ohms at typical room temperature.

  44. You are correct, spark duration and arc duration are the same thing. In your case this setting may only just start to come into play a high rpm. The spark duration setting usually only comes in to play when you have a distributor with single coil and more than 4 cylinders. It is used to shorten the dwell at high RPM when there is not enough time to both charge the coil and spark for the full duration. As an example think of a V8 with a distributor running at 6000RPM. At 6000RPM one engine cycle (two crank revs) takes 20ms. All 8 cylinders have to fire in that time. Lets s

  49. I had time to play with this today. It looks like you can make it work as is. In the ECU's that dont have the serial data stream settings visible In PC link, it seems that the "requested short" data stream method is enabled by default. Realdash is compatible with that. In PC Link set the baud to 57600. In Realdash set the baud the same and set it to "use short datastream". Let me know if it works for you. I tested it on a couple of my test ecu's and it seemed to work.
