As far as I know, this still hasn't happened. I'd be interested too.
The question is, using an external sensor (IE. o2), and plugging it into the back...how would you set that up in the gauge.
Quote:
The two analog inputs can be configured through menu choices. A linear conversion can be entered so that an analog signal
connected to the gauge can be read in appropriate units. These inputs are handy for pressure signals such as those from MAP
and oil pressure sensors, analog outputs from Air/Fuel ratio kits, etc. These signal can then be read and recorded along side the
other parameters obtained on the vehicle's bus.
I can only assume they're referring to their upcoming A/F ratio kit. There has to be some other way to do it without the kit.
