Anyone know the model number or name for this unit? I bought it new about 15 years ago for 200-something. This is an old unit from before they all came with gauges.

It's a little aluminum box about the size of a deck of cards with two cables- one goes to a bosch wideband sensor, the other has various outputs (narrow/wide) for the ECU, gauges, etc.

The AEM site doesn't have any references to it. I still have the manual to it somewhere, I just can't find the damn thing. Which probably means I don't actually have it anymore.

 

Talked to the guy at AEM and he said it was the 30-2301.

Said it was long since discontinued, sent me the manual. Hmm won't let me upload it.

Ordered a new UEGO off Amazon for 150.
