i plan on getting the AEM UEGO for my 96 eclipse gsx and i saw that there are different models. (ex. 30-4100 or the 30-4011). also, are all of them universal? will it hook up correctly to my car? also, i plan on getting my car dyno tuned so my fuel management will be perfected. should i do this before or after i install the UEGO?

 

It doesnt really matter... But I would get it before you tune it.. Then you can make sure its working right when you get it tuned..

 

Yeah, just as long as you go with the UEGO set you'll be good to go.

 

agreed. They are all universal. Everyone uses the same basic setup. You will need a bung welded in your exhuast however, to install it for the O2 sensor
