  1. Hey people, Just thought I'd post up a quick note about something I did recently that worked out well. I was wanting to optimise ignition timing for cruise, so using some switches on my dash to trigger a combination of datalogging, 4D ignition, 5D ignition and the 2nd ignition table set to overlay mode. With the idea that I could add or remove timing from the main table in varying amounts without having to stop the car, and datalog the whole lot easily. Like so: Since you can turn on more than one ignition trim table at once, using those three you can get a combinatio

  2. Iecku, I just thought I would mention a little bit of info that many people miss. These kits appear to use the Honeywell 1GT101 sensor, these sensors are much slower on the rising edge than the falling edge. The datasheet quotes a 15µs rise time Vs 1µs for fall time. So for at least trigger 1 (that controls the timing) it would be more correct to set the trigger edge to falling. Even though 15µs is only like 0.9 deg at 10000RPM, if you can get extra accuracy just by a simple setting change - then you might as well use it...

  3. 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

  4. Hi, My other car has been off the road for ages, and life has been in the way. So I thought it might be fun to just wire up my ECU into the Echo so I could have a play around with some tuning stuff again. It's a 1300cc economy engine so not going to set the world on fire. But a bit of fun. I need/want to revert it all to factory though, so I bought a spare ECU from wreckers and cut the plugs out to make a patch loom. This car has VVTI on the intake side, which means I could do my usual sweep through the vvti angles and see which delivers the most airflow into the engine.

    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

  6. 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%

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 cou

  9. 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.

    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 platf

This is just for anyone that is interested in getting a few pops and bangs on a gearchange/downshift without having fuel cut off all of the time, and, with some overlapping 4D and fuel cut ignition tables. Disclaimer: I am not a tuner, simply a novice that is taking a bit of interest. Above are my settings for this. Cutting the long story even longer: The fuel cut is on, but it takes 2 seconds to initiate because of the "activation delay" parameter. Within these 2 seconds, we want

    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

  19. 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

  21. 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

  29. 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

  30. Im not sure how relevant this is, but here is the ignition table from our V11 JDM STI test car. EJ207, quad VVT. Dead stock, 98octane RON pump gas. Most of the cells that it runs in are steady state tuned and it doesnt take much more timing than this, its a couple of degress away from knock when IAT creeps up. It runs 240kpa boost up to about 5500 then tapers away to 220kpa at the top end due to running out of injector. All of the parts that are meant to be inside the engine have managed to stay inside so far.

    Normalised knock

    I've helped with development of the new knock normalised mode and done lots of Beta testing. The Knock Normalised Mode has the big benefit that it will adapt to increased noise level, when your engine wear over time and consequently produce more background noise. In tradional mode this will lead to false knock detection. In general speaking Knock Normalised mode will adapt to changing background noise levels and should need less adjustment from engine to engine, once you have a good basemap worked out. It also allows better adjustment how much ignition retard is applied, based on knock

  32. 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

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.

  35. 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.

    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.

    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

    Glad you got it sorted out Idris. But if you would like to get better information from the members of the forum, it would help if you supplied a bit more information with your questions. Different engine combinations sometimes benefit from different settings. And with your rather vague post, there is not much to go on to give you good suggestions. I hope this helps with your further posts on this forum. Have a nice day.

  44. Hi Adam, Just to close this off i spent a lot of time trying everything to catch the stall - as i said the gain and anti stall did zip from max to min values. It really needed a dashpot style fall to idle - which when ethrottle is setup the hold table is removed. I managed to create a vitual dashpot using a virtual auxillary triggering a timer and that timer controlling a slowed return to idle using the 3D idle table. Works very well and might be something others could use if they have a similar problem. My engine has a very light flywheel and two charger bypasses and 550cc under runner injec
