Are there any models of the plug and play AEM EMS that do not come with the UEGO Controller opotion?

I am seeing a very wide range in price on these units and am wondering if the less expensive ones do not have the UEGO and censor...

I know that if the model number ends with a U, then the UEGO is supposed to be in there.

 

Without UEGO 30-1012

With UEGO 30-1052U

 

Sweet thread! I wish they could all be like this lol
Good info though!
