MickeySteffo Posted June 3, 2017 Report Share Posted June 3, 2017 I'm reading through the manual and I'm unsure if i need to power the +14 on the b connector.As the ecu was given to me I don't know what firmware its got to select the correct pc link software [ Board Rev 1.2 Serial #15929 ]Also when i connect it to the computer its unrecognised by the computer and doesn't try to install drives like the manual says.Can not update firmware as the program can't find the ecuI don't know any history on it and don't even know if its workingAny help would be great, i just want to see if its workingCheers Quote Link to comment Share on other sites More sharing options...
Simon Posted June 6, 2017 Report Share Posted June 6, 2017 HiCan you see the ECU in Windows Device manager at all?It is a G4 unit so you will need 4.10.2 to connect to the unit.To check for PC coms you will only need one ground and the 14V on the A plug connected.

MickeySteffo Posted June 8, 2017 Author Report Share Posted June 8, 2017 Hi, thanks for the replyIt shows up in device manager as 'unrecognised device'Cheers Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 8, 2017 Report Share Posted June 8, 2017 Hi Mickey,That would normally indicate a driver issue. Attached is some more recent drivers than what comes with the old G4 software. Can you save this zip folder somewhere easy like on your desktop, un-zip it then double click double click on the correct .exe file inside that folder to install. If you have 64bit version of windows then the correct .exe to click is : Link USB Driver Install_x64.exeIf you have 32bit windows then the correct .exe is: Link USB Driver Install_x86.exe Link USB Drivers.zip Quote Link to comment Share on other sites More sharing options...
MickeySteffo Posted June 9, 2017 Author Report Share Posted June 9, 2017 Hi Adam, Ive tried the drivers you suggested and the ecu now isnt even coming up in device manager.The usb cable I have isnt the oringnal one, possibly pinned out wrong? Could this cause damage to the ECU?To confirm the pinout of the connector on the ECUPin 1 Not UsedPin 2 Not UsedPin 3 Data +Pin 4 Data - Pin 5 VCC +5V Pin 6 GroundAs stated in the figure, looking into the connector on the ECU.Thank you for your help Quote Link to comment Share on other sites More sharing options...
MickeySteffo Posted June 21, 2017 Author Report Share Posted June 21, 2017 Any help would be great, need to get this ecu working to do some data logging on university projectCheers Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 21, 2017 Report Share Posted June 21, 2017 (edited) Hi Mickey,Where abouts are you in the world? Is there somewhere local you can take it to try with a genuine USB cable? Edited June 21, 2017 by Adamw Quote Link to comment Share on other sites More sharing options...
MickeySteffo Posted June 22, 2017 Author Report Share Posted June 22, 2017 (edited) Im in Adelaide, Australia, none of the dealers near me sell this cable and im trying to get this sorted quickly.Im capable of re wiring the connector, just need the pinout Edited June 22, 2017 by MickeySteffo Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 22, 2017 Report Share Posted June 22, 2017 Ok, I just probed my tuning cable, that pinout above is wrong. Here's what I get:Pin 1 = USB GNDPin 2 = N/CPin 3 = D+Pin 4 = D-Pin 5 = VCCPin 6 = Shield (the metal case on the USB plug) Also be careful where you get your pinout from as I noticed when looking up the USB pinout on google many images have the D-/D+ swapped over. My numbering above is based on the pinout below that I have marked "correct". Quote Link to comment Share on other sites More sharing options...
MickeySteffo Posted June 22, 2017 Author Report Share Posted June 22, 2017 Thank you very much, hopefully I can get this ecu regonised by my computer and get this project moving along Quote Link to comment Share on other sites More sharing options...

Any chance you have the pinout of the usb port on the ECU? I want to make my own cable cause i need a very long cable. By the way the ecu is a link g4+ plug in Quote Link to comment Share on other sites More sharing options...

Adamw Posted February 12, 2021 Report Share Posted February 12, 2021 Brown = Gnd Green = D- White = D+ Grey = NC Yellow = VCC Shield is only connected at the laptop end. Note You can order these parts from any Link dealer. The internal cable is #CANPAN (short for wire-in ecu) or #CANPCB (longer for plug-in ecu). The external tuning cable is #CUSB.
