AEM EMS UEGO controller tuning - 3000GT/Stealth International Message Center

sugarbear7979 · 07-07-2008, 01:29 PM

Im using a single aem uego controller to do internal wideband tuning in the AEM EMS. What is everyone running on the AEM wideband controller when you run the o2 wizard? There is 4 different AEM sensors, so first i want to make sure its set up correctly #1 o2, and the gain is set so it reads correctly, because so far it shows 17:1 lean and its way rich out the exhaust. Now rather than having 2 o2 sensors for a single turbo im just running 1, but in the parameters view in AEMPro, im getting a #2 o2 readout of about 3.77 volts, but it doesnt seem to show an error or anything other than volts. Curious if this volt reading is affecting anything. I have taken the #2 o2 sensor out of the car, so i was wondering if this is what it is reading. Should the AEM EMS read anything in o2 #2?

Ive set the injectors to only read off lambda 1 in the options of the injectors, but it still may be affecting it. I want to enable automap, but all this ive noticed with about 2 hours or so of messing with AEM.

Also, what are most everyone using ignition timing/advance for say anything below 101 kpa? Im having trouble with getting it to idle below 1500rpm and unusual startup characteristics, and i think im just missing a small detail.

all these people running internal uegos and no thoughts?

Some AEM EMS boxes actually have a built in (internal) WB. The 3S box does not have this option.
If you are using an AEM WB Uego then you will choose AEM (External Controller), unless you are using the all in one AEM WB gauge then you would choose AEM (gauge).

nice nice, now what about the voltage read outs on o2 #2 if i took off the stock o2's and replaced it with a single AEM UEGO controller? Im getting roughly 3.77 volts out of o2 #2 and shows it in the parameters. Could this affect tuning or readouts? I have the injectors to only read off o2 #1 so as to not read off a sensor thats not there.

As long as all injectors are set to look at O2 #1 is does not matter what O2 #2 is doing.
