pretty sure all autometer gauages are narrow band.

narrow bands are just a half-assed BS idea of what it actually is. Buy a wideband kit.

And yes spike, Autometer makes wideband gauges with digital numeral output.

does it come with the sensor and controller or just the guage?

In any case, you can use a standard autometer narrowband guage and the Innovate Motorsports LC-1 kit. You won't have the numeric readout but the LED's are easy enough to read if you program the controller properly (easy as hell). Innovate also sells a small digital numeric guage (about the size of a key fob) that you can mount either in conjunction with or instead of the autometer guage. I have this exact setup and I like it quite a lot.

The LM-1 kit is nicer but more expensive. It's probably too much for your application or you'd know already. In any case, wideband is the only useful choice. Narrowband sensors only detect if it's richer or leaner 14.6, not exactly how much richer or leaner so they're not terribly accurate.

so narrow band is a waste of time and money?I'm saying wide band kits are a huge increase in price.

narrowband is a disco ball for your dash and not a damn thing else.

wideband is the only useful method. You should also try to decide if you "need" it or just want it. Guages you don't need are just more things to break and wideband sensors start near 75 bucks. You'll have to replace it, infrequently but nonetheless they're expensive.

I needed one so I could do my own tuning. Teal_beast needed on cuz he's running big boost. You probably don't need one but if you do you really do and should definitely not cheap out.
