    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 but the knock light status can be used to see when it occurs without needing to actually see the knock level above the threshold.

    Fury with MXS dash reverse gear

    Dave, this is an older MXS, not the 1.2 we sell. It doesnt look like they have updated the CAN stream in it. Even if I create a new MXS config from scratch in the latest RS3 the ECU stream version is still v00.00.01. In the MXS 1.2 the can version is V02.00.05

    Charge Temp Table

    Yes, but you will need a whole lot more energy than a heat gun. It not only needs to heat all the air, but the whole intake system, pipework, and anything else before the air temp sensor. You also want quite a noticable change in air temp - at least 5 deg, preferably 10. Blocking the intercooler airflow on a turbo car usually works or ducting hot air from exhaust or radiator into the airbox on a NA car is needed.

    Crank Sensor Trigger 1 output

    Testing is complete. All 6 injectors clicked. No ignition spark from any spark plugs...but i found my problem. The previous owner installed a relay to power the coils. The car has a power on and fuel pump on toggle and I found a broken wire from the fuel pump on relay going to the relay that powers the coils. The relay should have switched when I powered on the fuel pump but did not. As soon as I forced the relay I had spark....then the engine started once I reassembled the stuff I had taken apart looking for the problem. I learned a lot in this process and feel more comfortable with what I have. This started out with me trying to reduce the wire clutter. Now I know the wires I removed were not the problem so I will continue simplifying the remnants. Pictures attached of what we were working on. Should be able to make it to Watkins Glen in New York state this coming Monday. Thanks again for the support. All my work buddies (mates) have been told about then customer service you provide.

    Pulstar sparkplugs

    I would agree with Vaughan's comment, from the extra noise you have on the lambda trace it suggests you have a misfire or at least 1 cylinder with very poor combustion. It is definitely not due to an increase in torque or efficiency - probably quite the opposite.

    Suggested Settings for Mixture Map

    Yes, mixture map can be used from road logs. Set up a Transient filter Eng speed < 250rpm/sec and another with TP<5/sec will get rid of a lot of the inconsistent data. Here's a video I done for someone else earlier with some further info: https://1drv.ms/v/s!AiYbYlZQuRHPszz5hTxJ8ec0MitL?e=2JbDVh

    Combining Power Grounds?

    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. I have seen many fails in my time where the installer has assumed because the ECU works fine with a 5A fuse that they only need a ground capable of 5A. All ground pins are connected internally to the same ground plane so I cant think of any electrical theory reason to do so, I suspect this is more just a statement that was made to encourage installers not to take shortcuts on arguably the most important wires.

    Combining Power Grounds?

    Was the intent of that "DO NOT JOIN" warning mostly so that someone doesn't combine too small of a gauge wire to all the power ground wires or was it more for noise immunity? Just intrigued.

    just checked again and yeah, that seems to be right. Though I swear yesterday I checked it was showing all options for all GP outputs without assigning a pin. Thank you

    Combining Power Grounds?

    It should be ok through a single pin provided it can handle the current with a good safety margin above steady state to allow for in-rush and minimal voltage drop etc. An Xtreme for instance, 10 aux outputs capable of 2A each, 8 inj drives capable of 5A each = 60A total ground current fully loaded = unlikely to work through a single ground pin... However if you only have 4 x injectors that pull 1A each and a few auxes pulling 0.5A then a single ground pin would be fine.

    High Cam crossover Knock windowing

    Put your cam aux status on one axis of the knock target table. In my experience the 2ZZ is very prone to knock on the low cam but not really needed on the high cam.

    LINK G4x

    Freezing is generally a comms drop out, often caused by extreme electrical noise. Do you have resistor spark plugs fitted? There are some changes to comms in the next software release which is coming soon that may help it recover quicker when comms is lost. I think the engineers have got to the bottom of that now, they found some laptops would put the graphics cards into low power mode whenever not connected to AC power which made everything feel very slow. In the next release they have taken a lot of load away from the graphics card so you should see a big improvement.

    Aux port triggers

    Most of our plug-in ecu's only have low side drive aux outputs as OEM applications rarely use high side. Only the Storm, Xtreme, Fury, & Thunder wire-in ECU's have high side drives available.

    The DI's can be switched to ground or to positive, they can be set up to work either way. So you should be able to just connect it up to the stock wiring and it will work.

    I came up with a setup that; if I hold brake and clutch for 3 seconds after key on, my cruise switches become motorsport style buttons. Here's the setup for "Track Mode", Virtual Aux 1 is Clutch and Brake Switch Start Timer 1 with Ignition Switch Start Timer 2 with Virtual Aux 1 (reset it to 0 if virtual aux 1 turns off) Virtual Aux 2 says: If, after 3 seconds, Timer 1 and Timer 2 are equal, then Virtual Aux 2 is on, when you release the pedals, the virtual aux stays on because of condition 3 (that it is on) Virtual Aux 2 is now "Race Mode" you can use this to perhaps richen up a mixture, or as a switch for high boost mode. I also reprogrammed in Track Mode, so that Cruise Resume increased my traction Slip % (Though you could use this for launch RPM or boost level) Cruise Set reduced this. Cruise cancel activated launch control. Cruise On/Off activated pit lane limiter.

    G4 PCLink - Red Text when Offline

    Hi there, When I'm checking things out offline -so not connected to my ECU - when I change parameters, the text goes red -- presumably to identify to me that I've changed that value but it isn't loaded to the ECU, I don't know. However, red text on my laptop screen against the black background is impossible to read - I've tried setting different colours in the themes, but none change this particular colour. Can anyone help? Cheers!

    Fury or thunder X

    I chased engineering last night to get a feel for what the delay was. Most of the other G4X's ECU's we had quite a large stock of prior to all the covid stuff, but the Fury was just entering production at the start of it all. The long shut down of most of the major electronics manufactures (mostly China) and the consequent stockpiling that many of the large manufacturers done has caused worldwide extinction of several needed electronic components and a massive backlog for the component producers. At the moment we are waiting in the cue like everyone else with no firm ETA sorry.

    You need to bias it more towards water temp at idle as the air is moving through the port slowly it picks up more heat from the hot manifold and water jacket. Typically charge temp approximation numbers will be up around 70-90% at idle. You can see the E-throttle target is stable, but your TP is bouncing around a lot, this means your E-throttle PID needs work (not idle PID). I suspect due to the throttle bouncing around as above, the throttle stablises a little when the fan is on so MAP is much more stable and therefore PW is more stable. The unstable TP is also causing a little bit of accel enrichment to kick in.

    OBD2 hasnt been implemented in the G4X yet sorry, it is being worked on. For your dialog problem, I suspect it is the windows display scaling, it needs to be set to 100% for PC Link to function correctly.

    Ford TFI to trigger atom x

    Correct. Another option to look at is VW 0986221015. These are a 6 cyl wasted spark coil with ignitor built in, so no need for an external ignitor. You can often get the whole coil for less than the cost of an ignitor.

    Ford TFI to trigger atom x

    Most igniters will current limit at about 7A. So if they don’t happen to fry themselves straight away then you will only have about 3.5A available to charge each coil, it’s going to be a very weak spark.

    kind of common for people to damage the teeth on JZ crank sprockets when they remove them but dont remove the tab on the intake side of block first, usually ends up ripping the trigger wheel off the back of the sprocket

    As far as I know the tacho gets its signal from the ignitor in these cars. Have you changed any of the ignition system? I suspect AC maynot work until the control units sees RPM.

    same setup seems to be working for me here, do you want to attach a copy of your basemap? Also just to clarify did you setup that math block before making that log? The math blocks only work in real time and can't be backdated through logs.

    The settings overflow/underflow will be solved with a firmware update - basically it is just a scary warning that there is a setting out of bounds, it wont effect the way it runs. The re-lock thing sounds more worrisome, like some serious interference or something. Does it have resistor sparkplugs fitted?

    Engine died while running

    With the ECU unplugged, can you confirm there is +12V on pin 85 when the key is on. Then with the ecu plugged back in, with ign on, can you check there is +12V on pin 59.

    Engine died while running

    I suspect it is a wiring problem in your car rather than a laptop/software issue. Thats why it would have been good to test with your laptop while it was powered up on the bench.

    Engine died while running

    I think it is possibly fault code 30 that the green led is flashing. A bit weird as that is AN Volt 7 is on the ethrottle connector which looks like you have nothing connected. The blue LED on the bottom board is just the dash comms so that is irrelevant. I suggest to eliminate the possibility of a wiring issue is to pull the ecu out of the car and power it up on the bench. See if the laptop connects then. See this thread for an easy way to power it up:

    Engine died while running

    Lights should stay on a short while after turning the key off as the JZX100 has ECU Hold Power (For the idle stepper motor). Does the ECU stay on indefinitely or does it turn off after about 10 seconds? if indefinitely try unplugging it and plugging it back in to power cycle it.

    RPM Activating Early

    Ok, I can see why it is not happy, one of the cam teeth edges is sitting right on top of the crank edge that the ecu uses to sync. Something a bit weird with the position of your cam teeth compared to our internal records and all pics I can find online. Has this engine been apart? What do they have for teeth on the cam - are the teeth part of the camshaft or are they on a disk that can be moved? Here's a pic from the FSM, notice the cam teeth are nicely sitting in an un-toothed area on the crank: Compare to yours, the raising edge on the cam is very close to a rising edge on the crank: One thing I would like you to try - switch back to the "OBD2" trigger mode, but change trigger 2 to rising instead of falling.

    Idle Issues

    I'd start with fixing your knock. Seems like its pulling timing left and right. (even when you just rev it) Your DBW is in setup mode.. so not sure if you aware of that. Your IAT might be interfering as its adding fuel pretty much all the time. Raise your Overrun De-activation RPM in the range of oprating temp.. from 1500 say to 1800 see if that help with the dips. Last but not least.. I'd enable Idle ignition. That should help with rpms dropping as well. Hope this helps.

    Use the X-Series template that is included in the software. You will not be able to use the status or error data as AEM enumerations for status and errors are different to ours. You could input them as CAN AN Volt channels as a diagnostic if you really want to but it is unlikely useful. Link use a resolution 0.001 for lambda so there is already a native divider of 1000 built in to the software. AEM use 0.0001 resolution, hence divide the input by 10. You can use the test calculator to see how it works. ID should be 384 as per the help file article for the X-series. AEM use Hex, Link ID's are in decimal. 180 hex is 384 decimal.

    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
