This is specific to JUST the Defi D series A/F gauge...
Does anyone here use this gauge? It is based off of the 1 volt O2 sensor, but, it's output is based upon the ratio output.
If I am idling, the gauge tends to sit at 14.5:1 -- but on WOT, the output doesn't do much else.
Letting off of the throtle will drop the ratio to 17:1, which seems right to me.
I understand the output will not be accurate, but, I am just looking at trends... (And the gauge was free)
Any experiences with this gauge?
I tapped off of the ECU based off of the 2004 WRX (pin numbering was from ravens _blade website - my first funny issue was I was looking at the pin numbers and looking at the actual wire plug -- not the pins on the ECU itself... geez...)
