ok so AEM offers 2 types

1. Gauge-Type Wideband UEGO Controller

2. Wideband UEGO Display Gauge

i think the difference other than price is that the second one listed doesnt come with the o2 sensor. but if thats the case, then how is it hooked up?

also i was told that in order to instal one of these a/f gages that all u have to do is, weld the bung into the exhaust and instal the o2 sensor into the bung, then supply power and u are good to go. is this correct? also where on the exhaust does this bung have to be welded? pre-cat, post-cat, test pipe, where?

 

anyone?

 

Mount before Cat if you have one. If not then anywhere in the exhaust stream will work.

The second one is assuming you already have a wideband O2 sensor from some other kit like an LM-1.

 

ok so mount pre-test pipe in case i decide to put my HFC back on, and get the first one. ok now what about install?

 

Should be pretty straight forward. I'm sure it comes with instructions. The hardest part will be routing the wiring to the sensor. You'll have to have someone weld a bung for the O2 into your DP then.
