Subiwgn96 Posted May 30, 2020 Report Share Posted May 30, 2020 I have a link g4x for v1-2 subaru and I’m having an issue on getting the lambada 1 to actually read from the aem gauge/ sensor. I’m sure it has something to do with the calibration tables. I’m selecting cal 4 but don’t understand how to set a min/max output and what the values should be. I have it wired the white wire to volt 5off the gauge harness, so it should be connected right just having a hard time to get it to actually read on the ecu for lambda 1 Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 30, 2020 Report Share Posted May 30, 2020 In the lambda 1 settings you set the control to whichever analog input you have the wideband connected to. Set the calibration to linear cal 1,2 or 3. Then in the Linear cal set up the calibration values from the manufacturers datasheet. The numbers in the cal below are what most of the older AEM's use but you need to confirm yourself as there are a few different ones.

Subiwgn96 Posted May 30, 2020 Author Report Share Posted May 30, 2020 Would that calibration work for the 30-4110 gauge? Quote Link to comment Share on other sites More sharing options...
Subiwgn96 Posted May 30, 2020 Author Report Share Posted May 30, 2020 I read the calibration tables in the manual and they are slightly different. I ran the gauge with my expansion loom to analog volt 5 and set up linear cal 1 as you explained and I’m having the same result, it just stays pegged out on the link software Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 30, 2020 Report Share Posted May 30, 2020 What does the runtime how as the voltage on AN Volt 5? It looks like it is reading correct if your white wire is outputting 5V. With the sensor unplugged does it show 1.00Lambda or 2.35V? Quote Link to comment Share on other sites More sharing options...
Subiwgn96 Posted June 1, 2020 Author Report Share Posted June 1, 2020 This was with the car off. I’ll run the tests and see what it does This is with car not running and Wide and sensor unplugged no change This is with car not running and Wideband sensor unplugged no change Quote Link to comment Share on other sites More sharing options...

Need to know what the voltage of the analog input is showing, a copy of your basemap and short log might help with this Quote Link to comment Share on other sites More sharing options...
Subiwgn96 Posted June 2, 2020 Author Report Share Posted June 2, 2020 It’s the stock v1-2 base map on your preloaded maps and it’s outputting 9volts with key on engine off Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 2, 2020 Report Share Posted June 2, 2020 We want to know what voltage AN Volt 5 is reporting. It should be 2.5V with the sensor unplugged. If it is not then you either have wired it wrong or your AEM device is faulty. Vaughan 1 Quote Link to comment Share on other sites More sharing options...
Vaughan Posted June 2, 2020 Report Share Posted June 2, 2020 if the gauge is outputting 9V to the ECU then that gauge output isn't compatible (signal to ECU has to be with 0-5V). 9V into the analog will read as 5V and so will 1.365 Lambda meaning the calibration and analog input are working correctly but the signal you are feeding into the ECU is not correct. Adam and I were both looking for the voltage value that can be found in the runtime menu (F12) Analog tab next to Analog 5 as that is the voltage that the ECU is reading and passing through the calibration.

Subiwgn96 Posted June 2, 2020 Author Report Share Posted June 2, 2020 I didn’t realize that I could read it that way with the ecu I was using the multimeter I know in the instructions it says that wire is for the 5v output on the 30-4110 is that gauge compatable with the link software? What would be my best option as far as a gauge goes? I’ll reconnect it to the ecu I unhooked it cause I was scared to leave it hooked up and outputting voltage to high for that plug on the ecu Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 2, 2020 Report Share Posted June 2, 2020 If your gauge is outputting 9V on the white wire then either the gauge is faulty or your wiring is faulty. It should only output either a 0-1V, 1-2V or 0-5V signal depending on the position of the dial switch on the back. It should not be capable of outputting anymore than 5V.

Rossobianconero Posted June 3, 2020 Report Share Posted June 3, 2020 that is the old EUGO gauge, right? Quote Link to comment Share on other sites More sharing options...
Subiwgn96 Posted June 5, 2020 Author Report Share Posted June 5, 2020 I’m gonna hook it up tomorrow and see what it says on the computer but it is the 30-4110 gauge On 6/2/2020 at 7:58 PM, Adamw said: If your gauge is outputting 9V on the white wire then either the gauge is faulty or your wiring is faulty.

What should the dial switch be set at one the back of the gauge?

Subiwgn96 Posted June 5, 2020 Author Report Share Posted June 5, 2020 I bought a new gauge off amazon 30-3000 xseries gauge hopefully I have better results with that gauge than this one Quote Link to comment Share on other sites More sharing options...
Subiwgn96 Posted June 9, 2020 Author Report Share Posted June 9, 2020 I got the Aem x series and selected x series calibration it works now just waiting on the tune to make sure it’s showing the same values on the gauge and the ecu, I at least wanted it working on the ecu to properly tune the car Vaughan 1 Quote Link to comment Share on other sites More sharing options...
