Hi guys,

I currently have the UGEO wideband linked directly to the AEM AFR guage with the stock Comptech setup.

I've just bought the 1052U and will be tuning shortly.. What exactly do I do now?

Does the UGEO plug straight into the ECU?

Or do i unplug the stock o2 sensor and use that loom for the wideband?

If that's the case will I be able to t-tap the stock loom so i can still use my AFR guage on the dash?

Id there anything out there so i can use the serial output of the AEM to output to my tablet or phone? I saw something using bluetooth - I may just order the RS232 to bluetooth connector and scrap the guages!

Any help appreciated.

 

you remove your stock o2 sensor and replace it with the aem wideband one and you T tap the white wire to Oxygen sensor ecu wire

 

Is it not plug and play then? I'll have to get under the car tomorrow and find this white wire.. Cheers.

 

Did the 1052u include a wideband? If so then it has a different harness and will plug straight into the ecu

You can also cut the stock wiring harness and wire the wideband in. That's what people usually do on the 1052 and series2 because those don't have the seperate connector like the 1052u does

Note: the 1052u wideband is slightly different that the widebands they sell separately

 

Hi,

No the 1052u didn't include the wideband.

I was under the impression though that the AEM UGEO plugged directly into the EMS though using the same connector as my guage.. That's all good though.

So the way forward for me is to:

- remove stock o2 sensor
- connect the harness to the AEM wideband
- tap the appropriate wire
- put a bung in the stock o2 sensor hole
- remove wiring to my guage?

 

it states this in the UEGO instructions;

Analog Output
(Skip this section if you are not connecting the product to an AEM EMS.)
If the AEM UEGO gauge is to be connected to an AEM EMS, the UEGO gauge’s
WHITE Analog Output wire shall be connected to an EMS Lambda input. Locating a
suitable Lambda input channel can be done using the Application Notes provided with
the EMS. If the Application Notes are not readily accessible, a current list of AEM
Engine Management Systems is illustrated below. (Table 1)

Looks like i use the white wire as an output from the guage wiring? So I can keep the guage working too.
