  3. PCLINK crashes regularly still

    If you're running multiple instances of the software it could be crashing from a contention issue if they're both trying to access the USB/serial ports at the same time?

    We have issues with PCLink here if I have things like the Arduino IDE open that polls the USB ports continuously like how PCLink does.

    Could be worth a try, start up multiple copies of PCLink, turn off auto-connect and see if it stabilises?

    Thanks!  It seemed to help a lot yesterday, but today the program is crashing, while simply offline, reviewing log files.  Not sure what is going on???

     

  5. What are the two ports on the Link Thunder?

    in G4+

    Posted

    I'm still trying to solve PCLink software crashes and the ECU falling offline constantly.  I'd like to find some documentation that talks about the connection speed and baud rates.  I've been auto, manual, low speed, and after 5 days, finally decided to try a full speed connection.  It seems to be more stable.  I know there are two little ports on the Thunder case.  I have the USB cord in one.  What is the other?  Is there a third port somewhere?  RS232?  Can I connect to this device via bluetooth?  Can I connect a small tablet to it somehow?  Where will I find answers to these questions?

    Thanks!

  6. Link Thunder Documentation

    Is there any documentation provided for the ports on the Thunder?  Is it in the PCLink help file?  If so, is there a way to get it in PDF?  I do most of my homework on my Mac and I'd like access to it from there. :)

  9. Wideband O2 sensor compatibility issue with built-in lambda controller

    in G4+

    Posted

    I'm getting all kinds of funky errors with the internal lambda controller, using my AEM Bosch LSU 4.9 wideband O2 sensor.  I know there are a variety of sensors from Bosch (different LSU 4.9's even).  Mine has 5 wires.  The green wire is actually missing, but the connector still has 6 active pins.  The 6th pin (green) appears to be activated by a resistor inside the connector?  Does the Link require a specific sensor?

    No we are all on latest Win 10 here and PC Link is generally pretty stable.  Is there any specific event that you've noticed causing the crash?  I vaugley remember it could crash when some monitors go to sleep or wakeup but generally it is not something i see.  

    I continue to watch it and remember what I'm doing when it crashes.  Sometimes it's when I unplug from the USB cable, or maybe the external monitor.  It does it quite a bit if I try to run more than one session of the software at the same time (to compare previous files).

    I'll keep an eye on it.

    I thought I solved this issue when I changed the program installation location on the hard drive, but I'm still experiencing many random crashes of the software.  I'm running on Windows 10 with a mostly up-to-date OS.  I find that the software program crashes whether or not I'm online with the ECU or not.  Are there some known issues about OS updates that might be causing this?

  15. No spark on the Thunder

    The gen2 3sgte has 3 trigger sensors in the distributer, a 24 tooth, a 2 tooth and a 1 tooth. The sensor is on the cam and so needs to be called cam, when it is set to crank the ECU is looking for 48 teeth per engine cycle (crank rotates twice as fast as the cams).

    When doing a trigger scope don't click capture until after you've already started cranking the engine.

    When changing values in the Trigger Calibration window make sure you press the enter key, the box should turn blue when you have done this.

    Crazy.  That worked!  Thanks for the tip on cranking first!

    Dang!  Not yet!  I must not have the triggers correct.  I used the settings from the ST185 base map, but I'm a bit confused by then.  Shouldn't Trigger 1 be a "crank" input for Multi-Tooth Posn and Tooth Count be 24 (for a 24 tooth trigger wheel in the distributor)?  I get trigger errors that way.  I don't get trigger errors when I set it to "Cam" instead, but I still don't get anything on the Trigger Scope.  Timing light is working though, so I know there is spark.  I can't set the timing either.  No matter what I change the field "Lock Ignition Timing to" to, nothing happens with the mark on the harmonic balancer.  If I change the setting for the Trigger angle, nothing happens either.  What could be happening here?

    Ah, yes.  Spoke too soon!  It still won't let me. :)  I confused the software getting the Ign2 as the only active ignition channel, but it won't let me test that channel.  Good call on the wires!  I'll try that.  I wondered if it was that easy went I build Looms C, and D! :)

    NOW SHES FIRING ON THE TEST!!!  Check the timing and see it she starts!!

  19. What's the difference between AC Clutch and AC Request?

    you can but there is also a dedicated AC idle up solenoid also controlled by the AC amplifier which lets more air bypass the throttle body and so you might not even need to, it might already be covered.

    I think you are right.  I don't think I need to do anything.  I'll see what happens when I get this pig running!! :)

    I just realized I wired the IGT signal from the igniter into the Ign2 input on the Thunder, instead of Ign1.  I'm still battling these locked out fields in the software.  Where in the software can I assign this IGT input from the igniter to Ign2 instead?

    Nevermind.  Figured it out.  I have to switch my Ignition settings for "Distributor" to OFF, before it will let me change the settings to Ign2 for my IGT input. 

  21. Can I convert (mathematically) my old Haltech fuel map in pulse width (ms) to VE?

    Not worth the time, it will unlikely work out any closer than a generic table which will get it running no worries.  What engine?  Are you planning on using modelled fuel equation or traditional?

    Yeah, I just decided to start throwing out VE numbers and see what it does.  :)  I think I have a different problem though.  It's a 3SGTE.  I'm using the modelled fuel equation.  I don't have any spark, so that's likely the bigger issue.  I'll post a different question about that issue. :)

    I was thinking I would try to convert my old Haltech fuel map in pulse width (ms) to a VE value in the Link that might get me close enough to start the car.  I keep reading that VE is just a ratio of opening time to base opening time, but I'm not sure that helps me.  My Haltech software didn't use a base (master) fuel opening value.  It simply used an actual opening time.  Is it possible to do what I'm trying to do with some math?

    Request is incoming signal from the switch on the dash - it tells the ecu you want the AC clucth turned on.  AC Clutch is the output to the relay from the ecu that engages the clutch on the compressor.  

    There is usually a delay between these to events to allow the idle speed to be increased before the clutch engages and loads the engine as well as in some models there are other safety sensors connected to the ecu that influence whether the clutch is turned on or not - pressure switch and evap temp are common.  In the MR2's the safety logic is done by a sepearte "AC Amp".

    I remember there is an "AC amplifier".  I wasn't sure how this played a role.  Thanks!

    The MR2 ECU doesn't actually control the AC Clutch at all from memory. It just gets told when the Clutch AC amplifier has turned the clutch on.

     

    Ah, so would I just use the AC Request function from the button on the dash to signal the Link to raise the idle?
