Ok may be a stupid question but whats the difference between a wideband and narrow band a/f meter? Do I have to have a wideband to monitor or is a narrow sufficient?

To keep it simple:
Wideband:
Shows actual air to fuel ratio.
Precise, but costs more.
Required for FI vehicles and heavily modded vehicle, actually any vehicle if you want to maximize performance.
Narrowband:
Basically it only indicates a lean or rich ratio, it doesn't show actual a/f content. Cheap cost.
To be more specific, the wideband measures the mass of air to fuel. The lower the number the less air which means the richer you are, and vice versa. Definitly get a wideband
OK. Thats the answer I was looking for. Allen do your Interceptors monitor A/F? And what do they cost?
The Interceptors aren't that accurate at measuring AFR. However, Allen does sell individual widebands such as PLX that do a pretty good job. Innovate also makes a good wideband. I use my Interceptor to monitor KR, IAT's, and a bunch of other stuff.Quote:

The PLX stuff just dropped in price from $10 to $20.
Decide what you're going to monitor and how many gauges you want to clutter up the inside. Because, plx has a multi function gauge that monitors OBD2 data, and allows you to attach modules for boost, pressure and wideband readings, all in one gauge, with thresholds that can be set, and viewable in digital, analog or graph, also allows you to choose which parameters you want displayed.
Or, you can just get the three pod setup, a/f ratio, boost, interceptor setup.

multi gauge.
Then add modules as you need them.
They finally came out with a fuel pressure gauge as well!
I'm pulling all my crap out of the avalanche if you're interested.
Here's what's in it:
AEM wideband
Interceptor
Autometer:
Boost
Fuel Pressure
Pm Sent Allen!
