I'm in the process of getting an AEM EMS, and I'm not sure what model to get. I already have the AEM UEGO (Older style) WB. Is the 1313U a completely different unit than the 1313, or does it just come with the WB snesor? Can my current UEGO be used with the 1313 or does it not have the plug in on the EMS like the 1313U?

I already tried to do some research, including going to AEM's site. I figured I would ask here before making a call to a vendor or AEM themselves.

Basicly do I even need the 1313U? Any insight would be helpful. THanks!

 

Stay with the 1313 and an external wideband such as the LM1 XD16.
Very accurate and very smooth operation for closed loop on the EMS.

 

Thanks for the input!! So the LM1 is a better unit that the UEGO?

 

Yup, much better..

 

AEM's UEGO has always given me problems. I'd go with PLX/LM1.

 

I run the UEGO with my AEM EMS and have had absolutely no problems with it.

 

Lex - What type of problems have you seen?

I can say that it does swing quite a bit, esp on my rotary. But it appears to be somewhat consistent. I've never ventured outside the UEGO so I dont know what I'm missing.

 

You can use your AEM UEGO gauge with a non UEGO ECU. Simply locate pin #76 (Lambda #1) and cut that wire about 4-5 inches away from the harness and spice it with the white wire (four plug harness) on the back of the UEGO gauge. This wire is a 5 volt output reference. Next setup your ECU for the external gauge type under the O2 sensor#1 wizard under the setup menu. Last step would be to cal the 02 sensor under the 02 sensor options menu. Set the gain to 1.000

Let me know if you have any more questions.

 

Awesome, thanks DynoDude55!! Answered all of my questions in one post. Time to spend some $

 

No prob. I think it is kind of pointless to buy a UEGO ECU when you can buy the gauge also. It is nice to know what you A/F's are while crusing around by looking at the UEGO gauge and know thats what the ECU is reading also.

I would recommend that you install the Bosch Sensor within 6" downstream of the turbo and you can unplug the factory lambda sensor under the coil-pack cover. If you are running race gas the bosch sensor won't last very long (10-15 tankfulls). You will know quickly when your sensor goes bad because the gauge will read 13.4 all the time. If your running 91-93 octane than you should have no problems.

 

Thanks for the info, although I wish I would have read it two days ago. I just had a shop weld a bung on my new BR exhuast for my WB sensor, and they surggested a location that's further back than on my exhuast. It's now on the top of my TP. The guy said I would get the same reading as if it were on the downpipe, but now there's less chance of moisture getting on the sensor, which he said will cause it to fail due to it effecting the heating element.


Hopefully this won't effect to much. I do notice that my A/Fs look the same as they did when I had my other exhuast on, where the bung was welded about 6 - 8 in from where the DP meets the O2 housing.

 

aem ems and aem wideband combo work very good for me, ried lc-1 before was such pita
