AIR/Fuel Ratio Gauge

[silverfbimmer]

I am going to install a AF ratio gauge in my car and I was wondering if anyone had any advice on what company I should get the gauge from and how should I install. I think the M20 has a narrowband O2 sensor but I wanted to make sure I get the facts straight before I do anything! THanks!

it's worthless with a narrowband sensor..

I'm with nando on this one. A narrowband a/f guage is nothing more than a light show. Useful only for VERY basic tuning.

go wideband or go home

innovative and techedge are popular for those running aftermarket engine management. i think k&n might make one but i am not familiar with their product. some support monitoring via laptop or you can add on a gauge

if you're interested in this for monitoring, you can go one of two ways:

1) install the WB02 sensor in the existing bung and have the innovative, techedge, etc provide a simulated narrowband (NB) to the ecu. not all units support the simulated NB

2) have another bung installed and put the WB02 sensor there.
