    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 relatively cheap ranging about $3-$10. One example below. Right now it wont work on the Atom, Monsoon, Kurofune or Black Storm as the serial stream is not enabled in those ECU's but we hope to enable that setting in the next couple of months. Right now it will work in the Blue Storm, Xtreme, Fury, Thunder, all Plug-ins & Force. It will also work on old G4/Vipec V series ECU's. Connection to your tablet/smartphone is direct using your normal Link USB tuning cable, for phones/tablets that only have a micro USB port you will need a "Micro USB OTG adapter". Instructions for setup and connection attached to bottom of this post. RealDash.pdf

    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% of the way towards the lower RPM value and 25% of the way towards the lower Load value. If we interpolate these values, as per what the ECU does. Note: I have just titled the columns and rows with percentages to show what percentage of the each cell we are interpolating from. We get a value of (25% * 25* 10) + ( 25% * 75% * 30) + (25% * 75% * 20) + (75% * 75 * 40) = 0.625 + 6.075 + 3.75 + 22.5 = 32.95 is the table value that interpolation produces. Now lets say that you wanted to add 10% to this value. If we just adjust the closest cell by 10%, as per current Mixture Map strategy. Then our bottom left cell changes to 44 so our table now looks like this: If we do the interpolation again, but with the new value to represent running the car again after the update: We get a value of (25% * 25* 10) + ( 25% * 75% * 30) + (25% * 75% * 20) + (75% * 75 * 44) = 0.625 + 6.075 + 3.75 + 24.75 = 35.2 as the new overall value. Which is only makes 6.8% difference to the interpolated value, rather than the 10% we wanted. On the other hand... If PCLink De-interpolated the 10% that it wants to add. Instead of adding 10% to the one cell, we split the 10% addition across the 4 cells based on the same percentage that the value was interpolated from initially. So: Top left cell: (10 * 1.1 * .25 * .25) = 0.6875 Bottom left cell: (30 * 1.1 * .25 * .75) = 6.1875 Top Right Cell: (20 * 1.1 * .25 * .75) = 4.125 Bottom Right Cell: (40 * 1.1 * .75 * .75) = 24.75 = 35.75 is the table value that de-interpolation produces. We were trying to add 10% and this new value produced is 10.5%. So that's pretty good! (The 0.5% error comes from rounding to 3 decimal places in my example) So it's accurate to the provided data in every instance. Which is especially relevant when it's applied 1000s of times across all of the cells. You dont need to throw away any of your recorded data, it all contributes to the cell values. Mixture map is pretty good for roughing out a map initially but because of the inaccuracies of the "nearest cell" method I don't really use it that much anymore when trying to dial in a fuel map. You always overshoot or undershoot unless you set your cell tolerances impossibly tight and have millions of samples. And, since this is all only done in PCLINK rather than the ECU, there's not really any worry about the overheads of the extra maths involved. It's worth having it chug away for a few minutes longer if you can get an awesome result on first or second iteration of Mixture map logging. So - that's my Friday night suggestion. Thanks for reading if you got this far, haha.

    'Save All' logs

    Would this be at all possible? Instead of having to save each individually?

    EFI University or HPA?

    Hi All, Ben here from EFI University. Honestly, you really can't go wrong with any of the choices out there. Ben and Andre at HPA do a really great job and we have nothing negative to say, in fact a lot of our customers tell us they've used both and learned things from both. We try really hard to focus on giving our clients a real world "experience" by letting them actually put their hands on the dyno and doing the work. It's obviously a different approach to the learning process than an online experience, and we realize that due to cost and time not everyone can take advantage of this platform so we do offer some online training as well. As we move forward we may offer more of the online stuff based on requests from customers, but it's unlikely we'll ever transition to online only as it just doesn't stack up in real value to the customer the way a true hands-on experience does. I always like to use flight training as an example...you can only play on Microsoft Flight simulator for so long and eventually you HAVE to get into the airplane. No matter what, the experience will be different in real life so while we absolutely agree there is value in online video based training, our focus will always remain on training in a real world environment. I hope that was a helpful introduction and explanation of our core philosophy and if anyone had any questions don't hesitate to call or drop an email! Thanks, Ben Strader, President, EFI University, inc

    Mixture map defined by log window

    Wondering if it is possible to have the mixture map data filtered by the window selected by the time plot range? As in, if I have a section of log I want to zero in on, and be able to run only that section through the mixture map, similar to how the XY plots work?

    Just played with this, have updated V44 output baud rate to 115200 and changed connection to match and now have practically 0 lag between input and display. Very very happy boy. Now to play with some display config screens.

    Ok, tweaked version attached. You had most of it pretty good. I added the cal for the temp sensors, changed a few settings like VVT frequency and VVT target table was a bit messed up. There seems to be some 1ZZ's with 36-2 crank and some with 36-4 on the crank. The 2NZ mode you have set in your map is for the 36-2 version. If you get erratic RPM when cranking do a triggerscope and we will confirm what yours has. 1zzbasemap Boomslang.pclr

    [UPDATE] PCLink Released

    Yes I have hidden Ray Halls post for now until management decide what to do with it. He is upset that we arent giving priority to the relatively minor issue he reported some time ago (his car accelerates too fast when he presses the resume cruise control button). I told him there was a major firmware update coming soon but there were no changes to the cruise control function in it as far as I knew so he threw his toys out of the cot and posted a rant on here.

    Easy DI Function Search.

    Hi, Just an idea... It would be great if there was a way of searching for what a DI controls. For example, you have a DI x set to activate Boost. You may want it to do other things and have it activating a less agressive traction control, alternative fuel map etc. A simple "Search" for DI x shows all the things that DI x is assigned to?

    Engine protection question

    Note you can also make your main RPM limit table 3D to add extra parameters. Fuel pressure protection for instance if you use Differential pressure it should be relatively constant under all conditions so you dont need a full 3D table - you could just put it on one axis of the RPM limit table.

    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.

    Link CAN lambda and methanol

    My 2 pence worth , 0.65 on Meths is super rich but the difference between 0.8 and 0.65 lambda is safety the power difference will be very small from what I have found. We we was running a methanol drag car we was running NTK sensors but was only using the lambda's as a reference we looked upon the EGT's to get an better idea on how the car was running. Running CLL on full throttle on the Link is something that I would like to do but we dont have the ability to change the closed loop control from low load to high load like Syvecs. I.e have a much smaller adjustment parameter when on high load parameters and it would be good to have the ability to change the CLL % to a different figure from +(add) to -(minus) again like Syvecs.

    No it sounds more like whoever is advising you hasnt got a clue. Even the later "V2-3" ECU doesnt have ign2-4 on the normal 8 pin expansion sockets.

    Rev limiter quit working

    I have given your map a brief run in an ECU here and the limiting works as expected. We havent had any reports of a limiter problem for a long time so if there were one it could only be related to something unique to your set up. With so many variables involved it will be nearly impossible to reproduce without a log showing at least some of the conditions that were present at the time to narrow it down. Unfortunately I dont have much advice to offer except to suggest you set up ECU logging to always work in the background so you can get some insight if there ever is unexpected behaviour in the future.

    Windows tablet power from USB?

    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 film down.

    That and a few other handy features are already on my list of "Things that would make PCLink much nicer to use as a tablet dash". Thanks!

    EFI University or HPA?

    Hi Grant, In case my user name didn't give it away, I'm Andre from HPA We went down the path of online training because it allows us to help more people all around the world, and we firmly believe that it offers significant advantages to in-person training. It's a cost effective option since you don't need to travel, and you also have the advantage of being able to re-watch our courses as many times as you like. This means you can brush up on concepts that you're not clear on, or revisit concepts that you've perhaps forgotten since initially taking the course. The key to our courses though is our support community which is where we bridge the gap between online and in-person training - We believe strongly in supporting our members and this is where our private online forum and our regular weekly webinars help back up the course material. The forum is the perfect place to get fast and reliable answers to your questions, while our weekly webinars are the fastest way to expand your tuning knowledge on a range of engines and platforms, as well as staying up to date with the latest technologies. I couldn't agree more with Ben's comment about the requirement at some point to transition into hands-on experience and that's exactly why we developed our 'remote practice dyno' where you can get real world hands-on experience tuning a real engine on a real engine dyno without leaving your house. The online practice dyno is currently operating a Link G4+ Fury ECU which may be helpful to you given you're on this forum. You can find out more about the online practice dyno here: We understand that buying online education can be tricky and we want our members to be able to purchase with confidence which is why we also offer a 60 day, 100% money back guarantee - If for any reason you feel our courses aren't right for you, we will refund the full purchase price. If you're interested in getting a taste of what HPA is all about then I'd suggest you start by signing up for our free six-part series of lessons. This will give you some insight into how we work and what we can offer: https://www.hpacademy.com/free-tuning-lessons In the perfect world I believe the best solution is to get as much training as possible - Both in person and online. I found that when I was operating my own performance workshop however, that unless the in-person training was local, the cost of training staff in this way was usually prohibitive. I'm happy to answer any questions you may have
