Mohsin Posted February 16, 2016 Report Share Posted February 16, 2016 hello to all Link management membersi am just new to link so i am going to bother you little i recently bought link G4 plugin for my 3sgte st205 with extension loom installed the ecu and started the vehicle just need to ask where can i connect extension loom wires ?1st i have aem uego wideband iam trying to connect it with my link ecu i connected it on volt 7 pin is that fine ? but i m unable to activate it in link software..2nd i want to activate antilag for that purpose i would need a switch in clutch for flat shifting ? if yes then which wire will connect to the switch as there should be two wires...i would love to know about the other wires too and where can i use all of them when i needed it ? thank you in advance Quote Link to comment Share on other sites More sharing options...
Scott Posted February 17, 2016 Report Share Posted February 17, 2016 (edited) Hi Mohsin,Here is an image showing the ST205 expansion connector.Volt 7, 5, or 6 are suitable for a 0 to 5v signal from a wideband O2 sensor amplifier/controller. DI 4, 5,or 6 are suitable for switches.To activate the functions you need to go to the ECU settings section of PCLink and set the AN Volt or Digital Input channel to match the function you have assigned to it.For information on wiring up switches and sensors have a look at the PCLink Help > Wiring Information section. Generally a sensor that outputs a voltage requires +5v, Sensor GND, and an An Volt channel. A switch requires Sensor GND and a Digital Input channel.

Mohsin Posted February 17, 2016 Author Report Share Posted February 17, 2016 Wired up my wideband to analog input 5 and yes that was yellow wired activated it from pc link it is asking for values it is aem uego Quote Link to comment Share on other sites More sharing options...
Mohsin Posted February 17, 2016 Author Report Share Posted February 17, 2016 I am still unable to connect my aem wideband with my link g4+ please help me to configure it properly .... Quote Link to comment Share on other sites More sharing options...
Simon Posted February 17, 2016 Report Share Posted February 17, 2016 For the AEM you will need to select a custom cal, CAL 4 5 or 6 will do the trick.You then need to enter the voltage and Lambda values for point a and point b.Is this the AEM O2 unit you are using?http://aemelectronics.com/files/instructions/30-4110 Digital Wideband UEGO Gauge.pdfAccording to that the calibration should be0.00v = 0.683 Lambda (10.00 AFR Petrol)4.99v = 1.365 Lambda (19.98 AFR Petrol) Mohsin 1 Quote Link to comment Share on other sites More sharing options...

Just attached a refrence pic what and where i did .... Quote Link to comment Share on other sites More sharing options...
Simon Posted February 17, 2016 Report Share Posted February 17, 2016 (edited) The error values are for detecting a sensor error. In this case you will need to set the error low to 0.0V and the error high to 5.0VThen you need to go to the CAL 4 menu and set the points.

Simon Posted February 17, 2016 Report Share Posted February 17, 2016 That would indicate that the CAL figures are not correct or there is a earth difference between the ECU and the gauge.I'm not sure if the AEM unit is adjustable in with it outputs.To get the cal correct you may need to measure the actual voltage at 2 different AFR points and enter these into the CAL.

Mohsin Posted February 17, 2016 Author Report Share Posted February 17, 2016 For example?How do i measure the actual voltage ? Quote Link to comment Share on other sites More sharing options...
Simon Posted February 18, 2016 Report Share Posted February 18, 2016 If you set the AN volt input to a GP 0-5V input. You will then be able to see the raw voltage the ECU is seeing. (note you wont be able to display Lambda while doing this) Quote Link to comment Share on other sites More sharing options...

Scott Posted February 18, 2016 Report Share Posted February 18, 2016 Hi Moshin,The calibration for the 30-4110 and the 30-4100 look to be exactly the same:http://aemelectronics.com/files/instructions/30-4100 Digital Wideband UEGO Gauge.pdf Quote Link to comment Share on other sites More sharing options...
Simon Posted February 18, 2016 Report Share Posted February 18, 2016 Given the information Scott has dug up you will need to check the voltages from the unit for a given AFRAlso check that the ground for the AEM unit is to the same place as the ECU is grounded (Engine Block) Quote Link to comment Share on other sites More sharing options...
Mohsin Posted February 18, 2016 Author Report Share Posted February 18, 2016 how do i check the voltage for afr ?the wideband unit is grounded to chasis ..should i ground it from engine block as the ecu ?is that u meant? Quote Link to comment Share on other sites More sharing options...
Simon Posted February 18, 2016 Report Share Posted February 18, 2016 Yes if its just ground to the Body then it would be worth changing that and grounding to the block.To check the voltage you can check it with a volt meter or using the ECU with the input set to a GP voltage.

Simon Posted February 18, 2016 Report Share Posted February 18, 2016 Go for the Voltage 0-5 option. Quote Link to comment Share on other sites More sharing options...

Pointz Posted September 5, 2019 Report Share Posted September 5, 2019 Sorry to bring up an old thread but I am trying to get my aem wideband to show afr in pclink, I have set it up as above in Simon's post and all it shows is 0.684 as a value on digital gauge display! I have connected the white wire from aem to blue wire of my expansion loom (an volt2) as lambda 1 is this correct? Quote Link to comment Share on other sites More sharing options...

What voltage is present on the blue wire when the ECU reads 0.684? Please attach your map also. Quote Link to comment Share on other sites More sharing options...

Make sure to connect the AEM brown wire (Analog -) to a Sensor Ground (GND Out) on the Link. Without this connected your signal will not read correctly.

On my expansion loom the sensor ground is currently used for iat sensor can I splice into the same wire? Quote Link to comment Share on other sites More sharing options...
