Air/Fuel meter recommendations??

Every one of my cars has an air/fuel gauge. Their indispensible. Back in the day, the Innovate LM-1 was the sweet way to go. But Innovate dropped it and replaced it with the LM-2, which is awful. The AEM is fantastic. I'll be buying one myself for my newest project.

As others have said, don't waste your time with a narrow band unless you're using a secondary O2 sensor for EFI.
