    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 C. In my case You can see that pump is working very slowly till 50 C. It's because I need to warm the coolant up as fast as I can. If You change Aux PWM table values, You could get more linear interpolation. Last chart shows how output current is ramping up as coolant temp warming up. p.s: I have wired coolant pressure sensor. On full power pump is making 0.7 bar of water pressure in the system. These settings are good starting point. Thank You.

    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

    Here you go. Freshly out of my car. The calibration process is very easy the new way. Hats off for that. Not sure how the 4 offsets/teeth came for you.

    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.

    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.

    Running a KA24DE on the S15Link

    Yes, it should be no drama running it in a KA24DE car provided it has the 64pin connector and similar pinout to the SR's. The ecu has jumpers onboard to take care of the pin differences between distributor and COP engines as well as a few of the other pin differences. I know it works in almost all other Nissans that take the 64pin ecu, GTiR's, N14, N15, P10, P11 primeras etc.

    Yeah I think this is a decent idea, it could potentially also cover the drift guys that swap diff ratios regularly.

    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.

    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!

    No, with charge temp approximation biased more towards air temp the ecu thinks the charge temp is varying more than it really is so it applies more compensation. ECT is more stable so you need to bias more towards that so it gets less variation in the compensation applied. You have to retune the VE table everytime you change the charge temp approximation.

    G4 PCLink - Red Text when Offline

    I thought in the G4 they turned blue by default? In anycase I think the theme item "value changed" is what you are after? If you have a G4+ then the relevant theme item is called "value changed offline" G4: G4+:

    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.

    G4 Expansion Loom CAN PORT?

    Proper CAN bus structure is easiest to describe as a "daisy chain". So you start at one device, go to the next, then from the 2nd device to the next, etc. The first and the last device have to have terminating resistors. The ECU has a permanent terminating resistor built-in and the dash has a terminating resistor built-in that can be turned on/off in the software, so it is easiest to have one of these at each end of the bus and the Lambda in the middle. So two wires from ECU down to the lambda, then another two wires from the lambda back to the dash. If you use small wires you can just crimp two wires into a single pin at the lambda connector to save having to do a splice or whatever. Sorry for the rough drawing but hopefully gives you the idea:

    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?

    there you have it, like Adamw said, it just need more tuning. Usually you need to take quite a lot of fuel at higher rpm because like Adamw said, the efficiency of the engine drop (maybe no so much in a high na revving engine)

    Attach you latest tune after the firmware update and I will fix some of the idle stuff. It looks like the tune needs a lot of work though.

    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.

    Anti static wrist strap. https://www.antistat.co.uk/product/disposable-esd-wrist-band/ You're suppose to stay grounded while handling the ecu during the installation process.

    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.

    That's exactly what I mean. Thanks again. Initially (I mean with the G4+ yet) I had it at 15 degrees, but the engine wasn't happy, it didn't sounds good at all. Will give it an other try with the G4X. Thanks for the recommendation, will try and see.

    Couple of things on WRX107X

    A few notes: In G4X set your ethrottle target table to 0% at 0% accel pedal and set the idle base positions to the appropriate tps targets for idle. (G4X uses a clever bit of code to combine ethrottle and idle targets to ensure on exit of idle that the position doesn't dip). Closed loop idle only uses Integral control, Ignition idle uses Proportional and Derivative control Torque management help hasn't been done yet and that code isn't officially finished yet, I plan to test it more (has already had a decent amount of testing) and write the help for it either this week or next week. Accel sens was initially a single value but it was requested that it be made into a table to reduce it's effect "at the top end". I would recommend turning on asynchronous injection (under fuel main) and then seeing if you actually need accel enrichment, I found with my car that asynchronous injection is faster and more precise than a more traditional accel fuel. I'll make sure this help is corrected if I haven't already done so. Have a play with that accel fuel axis to see what suits your car the best, any feedback on this is much appreciated. I've attached a copy of the basemap from my 2GR-FE, It should be a half decent example of an ethrottle idle setup although I am not using closed loop idle, just open loop and ignition. vaughans_mr2.pclx

    Also I noticed you dont have accel enrichment enabled. You typically need plenty of this with ITB's. Looking through some of my files they seem to vary greatly, but below will be an average starting point. I have some files with 3x this amount of enrichment...

    advice setting Closed Loop Lambda

    Correct, the update rate should be more closely related to mass flow rather than RPM, in the next firmware update you have the ability to enable user configurable 3D table for update rate and gain. However, my policy with tuning is usually to only add complication where necessary, in my car even though I have the ability for a 3D table and I have tried it, I find just the 2D table referencing RPM is all I need. I suspect just a 2D table with something like "Air per Cyl estimated" on the axis would be a good easy option but I havent personally tried any alternatives like that yet. Edited the first line of this post as the 3D table comment should have only applied to the update rate, I was mistaken about the gain table.

    Trigger 2 noise

    Many thanks Adam, the 5l engine has a 347 stroker kit, the firing order is 351 as per custom cam grind specs, traction control noted. FP noted. yes ITB's, 48mm, home made when I had a bit of spare time a few years ago, will set the arming threshold in the morning and see what happens

    Trigger 2 noise

    Ok, no signs of trigger error in your log but it wouldnt hurt to bump that trig 2 arming threshold up to something more relevant. No other obvious signs of an issue in your log. A couple of comments after looking at your tune: Are you 100% sure your engine is using the "351/HO" firing order? I know from a previous case that some 5.0's use the older 289/302 firing order. Turn traction control off for now. It is not interfering in the log but with the slip aim at zero, it is going to start cutting as soon as the wheels start to turn. Set fuel system type to FP sensor since you have one, it will mean your tune is going to change but it will make your VE more realistic, make tuning easier and give you an extra layer of safety if fuel pressure ever drops. Looking at your Avatar - does this engine have ITB's?

    Trigger 2 noise

    You would want to set the trig 2 arming threshold so that it is above that noise level, but otherwise it looks quite usable, provided it doesnt get exponentially worse at higher RPM etc. In that scope capture your trig 2 waveform is about 6V high and the noise is about 0.5V. So if you set the arming threshold for that specific RPM to say 3V, then the ECU will ignore everything below 3V. Are you getting trigger errors reported or any other trigger error symptoms such as RPM jumping around? What coils does it have? Do you have ignitors? If you want to attach a short log of it running and the tune file I will take a look.

    Base timing

    The best option is to get your timing light out and check it. A good trick on distributor application is to set up the ECU as direct spark so the coil only fires once in a 720 cycle and then just move offset to correct position. This will ensure that you injection timing is correct even on a distributor application.
