Hi,
I have noticed that the AEM EMS system has UEGO with it.
What is the difference that between with UEGO and without it?

 

The UEGO is a wideband O2 system that is built into the EMS. The 1052U has it and the 1052 does not. To run a WBO2 on the 1052, you would need to add on an external controller and splice in the input. The internal would much easier to wire up and probably cheaper as well.
