AEM O2 question
I have a 99 si boosted with an AEM EMS and AEM wideband. My question is do I need the stock O2s. I am assuming yes, but am not sure. Do I possibly only need the front O2 and can use a emulator for the rear (I have no cat). Or can I just tell the AEM to ignore the rear O2 and just read the front. The wideband is not feeding the AEM either...all it feeds is the air/fuel meter. The car is obd2 and the AEM is the obd2 EMS.
Pretty basic stuff but I don't have any experience with this EMS and turbo setup. Thanks for the help.

Re: AEM O2 question (BlownBlackSi)
aem ems DOES NOT use the factory o2's at all, might as well remove them and plug them. it DOES need a wideband o2 though, which is where your uego gauge comes in, put that BEFORE any cats, and that wires into the ems. i recommend you read the manual!
