  1. In the documentation for the MiniX PNP g4X ECU on the expansion connector pin 2 is not given a description/listed in the pinouts. In the g4+ PNP manual this pin is +5v.

    Is this an error in the manual? Is it still +5V (I was kind of surprised a +5v pin wasn't listed)?

    I hate that.  Many LSx engines are the same way.  Then you get the engines that have the timing marks on the flywheel in the bellhousing. 

    And with my hatred of timing lights, the engines that only have a TDC marks, make for utilization of "dialback" timing lights which require a extra electronics in the timing light.  My preference is the cheapest timing light possible.

    When I put the ECU in originally I was kinda stuck with just trusting and hoping the base map timing was pretty close (it has been on my subaru).... but I'm going to be going in and doing a bunch of work so time to make it right.

    Pull number 1 spark plug and rotate engine to find TDC.

    Make a pointer from a piece of welding wire and attach via a bolt on front cover.  Adjust to perfection.

     

    I was thinking along those lines... once I get the aftermarket crank damper on. Unfortunate that the stock engine has no capability to verify timing while running at all.

  4. I've got a g4x mini pnp on my R53 mini and I was wondering if there's a generally recommended way to verify ignition timing on an engine that has no crankshaft timing marks.

    I'll up adding an ATI damper which at least has marks on the damper but I'd have to add some kind of pointer to the engine side to actually make it usable.

    I'd think this would have come up at some point but I haven't seen any recommendations on how to do it. Or to do it right just a TDC type timing marker need to be added to the engine. Googling around doesn't show any examples of it being done.

  5. Are there mapping files for the g4x to aim dashes somewhere available as a base point for customizing?

    I know these were shared for the G4+ and made adding/deleting some signals much easier on both sides.

  6. I'm sure the mini Canbus was predefined to protect the work to decode all of it but I was hoping it's aged enough at this point that I could potentially get a breakdown of it so I can build a custom stream.

    1 reason is to allow me to use the Chrono Dash in the car, the other reason is to allow me to replace the stock column cluster with an AIM dash but saving me a ton of wiring by being able to use the factory CAN2 factory wiring.

    Any help would be appreciated.

  7. It is a stock ignition system. I thought it may be worse having the coil pack with the spark plug wire in between for checking timing but it didn't seem to make a difference.

    I guess if there's a hardware upgrade I'd rather just get it done now and be done with it. (does this require going back to the mother land?)

    I'll check that fuel temp.

     

    Yes I thought I was doing slow and digging around I saw that slow setting in the config. I'll try that change too.

  8. Unless I'm reading the software wrong it looks like there were some changes between the G4+ CAN parameters and the G4x.

    Example: IAT

    G4+ : Min -50, Max 150, Display Offset 50 (all degF)

    If I put 75 in the test calculator for a PClink Display data I get CANbus Data of 125

    G4X : Min -50, Max 500, No Display Offset listed

    My dash was displaying an incorrect IAT which is what led me to look at this so I'm assuming there really is a change and that there isn't a default offset...

    Is there a list of CANbus parameters that have changed? or am I missing something? Basically I import all my g4+ streams into my g4X and I'm seeing incorrect values.

  9. I need to work through some comm issues before i'm able to actually try getting this working again but I wanted to see if someone could look through my maps and see where I'm way off.

    The cam timing offset numbers are not correct at all... can I test these on the g4+ and use all 3 values in the g4x? It doesn't look like the help file has any starting values. With my current comm issues I can't stay connected long enough to test and set them.

    The car is running, driving, tracking, idling, etc etc and has been for over a year on the g4+. I, as best I can tell, have transfered every parameter over to the g4x program. However with the g4x installed the car will barely idle. I did the MAP cal, APS, Ethrottle cals and was able to force enough idle throttle percentage to be able to check the base timing which was close, only needed 0.4 adjustment.

    I don't have any logs as I was getting frustrated restarting my laptop over and over again as it kept losing comms and locking up.

    I'm either missing something stupid or my ECU has an issue.

    Oh, these are both WRX104 PnP units. Zero wiring changes between them. Just swapping the ECU board inside the case.

    Can you try moving you axis setup window across to one side of the screen before clicking the change parameter button? I suspect the parameter selection window might be coming up behind the axis setup window for you.

    Yep, that's what it was. I tried doing this after hitting the change parameter button but not before. It's also now popping up in front when i'm not connected. Not sure if this is just a random windows type issue or what. I'll make sure to try it again connected to the ecu when I get back to swapping.

  11. Have there been any real solutions or resolutions to the comm issues?

    I tried to upgrade from g4+ to g4x yesterday and basically wasted 2 hours trying to get it going before swapping back to the G4+. I can't stay connected long enough to even do anything with the engine running. I'm also seeing other odd stuff that's off topic for this discussion thread.

  12. When I'm in the axis setup area for a table I have an issue that I can't select or change an axis parameter.

    If I hit the button to select a new a parameter for an axis it acts like the window is open (dings if I try to do anything else). I have to hit esc to "close it" but I see no window and cannot select a parameter.

  13. Replace the subaru controller with a Jag XJ controller.

    That's what I ran on my subaru before I went brushless. I also ran it with and without a cheap amazon voltage booster/regulator up to 16V for more flow.

    They're easy to get under $100 and I can get you connectors if you're in the US.

    You can use the TVS diode as per your other post.

    Thanks Adam... Wasn't sure if that would get buried over in that section.

    I ended up using I think B6 and D3 on the header and that worked just fine as well.

  15. Doing a search it looks like the older ECUs had a convenient spot on the board to power up the PnP ECUs. I've got a WRX104 g4x coming that i want to power up on the bench so I can get that software dll issue resolved so that I can get my tune all transferred over from g4+.

    Is there a convenient spot on the g4x board to do this? or should I just power all the appropriate pins at the header?

    Error 16 on the lambda is generally power supply wiring related.  Either the wires are not capable of the required current, or there is excessive noise on the power supply circuit.  If it is not connected to its own relay, but instead shares an existing power supply with other devices then try fitting the 22uF capacitor as per the "Alternative" diagram in the quick start guide. 

    The backfire we have found is due to a hardware issue that seems to mostly effect subaru's.  The ecu will have to be returned to your closest regional office for a hardware fix.

    If I just purchased a wrx104x ecu will it have the hardware fix done?

    The attached map will be closer.  I have made quite a few changes based on our latest V10 map, but the main problems with your E-throttle set up was the PWM freq was 100Hz instead of 1000Hz and your E-throttle target table was just zeros.

    I'm assuming the g4X PnP have configurable Ethrottle frequency then compared to the fixed frequency in the G4+? That would be super nice as my big throttle body doesn't like the lower fixed frequency in the +
