  1. Hi All, The developers of RealDash have been working with us to make their app compatible with Link ECU's. It is now compatible. For those that havent seen it you can learn more here: http://www.realdash.net/ In my short play it seems to work well and has lots of cool features. Lap timing, navigation, configurable alarms, live graphs, live streaming of data, music player, etc. The app and a selection of basic "skins" are totally free, then there are some more fuller featured paid for "premium skins" that do more stuff such as data logging and may look cooler these are still r

  2. Hi, Currently with mixture map you set a threshold so that samples within say 25% of the centre of a cell vertically and horizontally. This pool of results are used to contribute towards an average value in the centre of the closest cell. However this means that you've got 25% variation of rpm and load, contributing to a static value in the centre - and you need to throw away 75% (?) of recorded values. I have another idea that can let you use all of the data instead, and improve the results. For simplicity's sake imagine a 4x4 grid, and our current load and rpm point is 25%

  3. 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.

    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

    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

  10. The continental Ethanol Content Sensors will read significant lower when low flow goes through the sensor. This means during a WOT run the ethanol content will read significantly lower at high load and rpm than at idle, because the flow in the return line is low. I attached a Log to show the problem. With more boost, I see values 20% lower at WOT than at idle. This is a well-known problem and other ECU manufacturers have an Ethanol Clamp function for a good while. The Ethanol content does with activated clamp function only update when the Injector Duty Cycle is below a certain leve

  12. Guys relax a bit. I've mapped and I'm supporting several 600-800hp 2.0 to 2.3l time attack engines/cars with a Link ECU and multimap strategy. Such an engine runs usually for 5000 race track kilometers until a rebuilt is needed. That's a similar distance to a 24h race. I like to answer your question.: All LINK ECU use the same PC-Software and the same Firmware. The main difference between all LINK G4+ ECU's is only the hardware. your tuner should tune the main Fuel and ign Maps from the lowest to the highest boost levels. There are 3 main Boost Maps in the LINK ECU. You can

    Closed Loop fuel trims

    Regarding Lambda control error correction table. I spend alot of time to tune these. The base map is adjusted the wrong way around. Because the error correction tables is a % corretion of actual error, you want big corrections like 15% on small errors (0.03 lambda error) and small correction (like 5%) at the biggest error on the table. This is because a fuel film built up first in the ports when big correction are applied. This means it needs several burn cycles to get the whole change applied and measured. This means lambda control applies big changes two or three times for big corrections w

  18. Okay so there are a few stages to setting it up. 1. Wiring Run one wire to the knock1 or knock2 wire on the link loom, and one to sensor earth, polarity unimportant. must must must must use shielded wire. The knock sensor outputs a very low voltage signal that's prone to interference. 2. Initial settings Since you are using the 'wideband' knock sensor and an engine with an ~86mm bore has a knock frequency in the ~6khz range select your Freq Channel as 4-10khz Wide Band. Set Ignition Retard limit to 0 degrees. Set the RPM high and low lockouts however you like. (500rpm likely not ideal for

  19. 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

  20. 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.

  22. 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.

  26. I just had a quick look. There is some pretty odd stuff in there. It looks like it has been tuned for flex fuel but there is only one ignition map and no other corrections for ethanol content. Usually E85 can take a heap more advance than petrol so what fuel was that ignition table tuned for? VVT looks like the offsets are set incorrectly. The RH inlet cam is showing 10deg advance when it is in the fully home position. That means it will be getting 10Deg less than what is commanded. The VVT and ignition tables both have big "holes" in them around the cruise area that is

  28. Thank for Realdash developing such a powerful app that I don't have to buy expensive AIM racing instruments. My car is Subaru GRB, ej25 with link G4 + thunder. I developed a protocol conversion module using STM32. Then can convert the Can signal of the link G4+ into a Realdash protocol, and then connect to the mobile phone through a TTL to Bluetooth module, so as to display almost all the data on the mobile phone (as long as the PClink can display).

    Nos control

    I think its much better to have all universal function like virtual aux, timers, 4D, 5D, fual fuel table etc. than a dedicated NOS function. This way you can build your own NOS function excatly how you want it. You just habe to be a bit creative with the universal functions.

    CANBUS OIL Temp from AN8

    Hi Mark, I suspect the problem is your oil temp sensor being on a AV input is not actually assigned to the "oil temp" parameter but rather a "GP Temp" parameter that is not sent in the standard generic dash stream. Attached below is a configurable version of the generic dash stream where I have replaced "oil temp" with AN 8 - Oil temp. MarkHellier.lcs For any others that want it I will also attach an un-modified configurable generic dash stream. Configurable Generic Stream.lcs

    Closed Loop fuel trims

    Hi Marc Good to hear back from you. How much does your AFR oscilate? Where is the wideband located? Depending on position, you need to adjust Lambda rate and Gain. You should do some testing. Tune your VE table with CLL off as good to your Target AFR as possible. Adjust your target AFR table to the rich side with one task by the amounts listed in the gain table 0,33 0,66 etc. And log, with a high logging rate, how long the sensor needs to get to a stable reading. Lets say it needs 0.3 seconds. This means your frequency in the lambda rate table may be max. 1/0,3 = 3.333

    Wire schematic

    Hi To speed up wiring and diagnostic I would like to have a function that outputs a list, a schematic, and a picture of the connectors with all labels of all configured (assigned) in- and outputs. On top of that many smart things could be implemented like an auto updated complete wiring schematic in an easy understandable format(e.g MS Visio style). These things can speed up install time and wiring a lot, which sets barrier lower to switch to a standalone ECU. possible examples attached.

  35. For anyone else looking to run similar setups with Racepak dashes and a link ecu. Don't purchase the Racepak display dash or logger dash that has the standard 5pin v-net connector and 8pin Deutsche connected on the back. If you purchase the Racepak STREET dash it has a can module already built into the dash that can be programmed to most new ecus and I have tested and confirmed it on my link G4+ extreme.

  38. After doing a bit of research recently into running a tablet as the primary dash for my car here's some thoughts... Hardware: For the older Windows tablets using Micro usb you should be wary of any claims of being able to charge and have a device connected, a lot of descriptions of the adapter cables are wrong as it totally depends on the tablet, so make sure you do your research first, if in doubt it likely doesn't support both at same time. However I believe the new tablets which support USB C may be better in this regard, again do your research first. Performance of PcLink on lower speced

    g4 tablet dash

    You can configure the look of PCLink however you like, but doing it on a tablet could be tricky. One solution would be to design your layout on a laptop/PC, save the layout file (Layout > Save Layout File As..) and then email it to the tablet and then open it in PCLink on the tablet. When it comes to actual design of the layout, you can add new pages by clicking Layout > New Page. You can add a gauge wherever you want one by right clicking in some available space and then selecting the gauge type you want.

    EGT Conditioner

    Hi Guys, EGT-K 2CH power consumption is ~2-3mA @ 12V. OUT ground is internally connected with IN ground. Sensors ground in your ECU is chassis ground with separate filtering for analog circuit - right? You can connect it in two ways: Using vehicle ground (chassis ground): - EGT-K OUT signal to Adc input in ECU - EGT-K OUT ground left floating - EGT-K VCC input to +IGNITION or +BAT - EGT-K GND input to -BAT or chassis ground. Using ecu sensor ground: - EGT-K OUT signal to Adc input in ECU - EGT-K OUT ground to ECU sensor ground - EGT-K VCC input to +IGNITIO

  47. Copy all the injector data from the base map "G4+ Xtreme Black Sample.pclr". This map is from one of our test cars that uses those injectors and we have tested them in-house. For an engine size of say more than about 500cc/cylinder with 1000cc injectors I would say it is not so critical as the idle pulsewidth is usually still in their linear region. It gets more important with larger injectors or smaller engine capacity from here.

  48. Another thing which I would like is a 3D Accel Cold correction table so it can be spanned with Engine running time or charge temperatur or a modelled intake manifold temp. The reason is simple. Just after cold startup, it needs much more accel enrichment, than after 1-3min running time of the engine. From a tuning perspective, you need to add a lot of accel enrichment just after the start of the engine so throttle response is good. But after 1-3min running ECT is still similar, but manifold ports have got some temp into it. Now the big Accel enrichment just flushes the cylinders and oil

    The Dash Cluster temp meter is fed direct from the ECU, it will always read cold with every aftermarket ECU apart from Kaizen Garage's ZZE/ZZT Adaptronic based plugin which has an additional circuit onboard to convert the signal to one the cluster can accept. The stock ECU outputs it's engine coolant temperature signal for the dash cluster from pin B-17, on the 22 pin ECU plug. PCB pin THWO. You can trace the signal with an oscilloscope using the stock ECU from dead cold to operating temp and then use an audrino or similar to create a module that will convert one of the vipec outputs to a s
